10 Round capacity. 

Newest Version.   (updated January 31, 2020)

Locks into your magazine well with an expandable insert built right into the side of the CompMag.

Our unique fixed magazine design creates an ammunition feeding device designed to be contained in or permanently attached to a firearm in such a manner that it cannot be removed without disassembly of the firearm action.

Allows you to keep the AR-15 features you love on your rifle. (pistol grip, forward grip, retractable stock, and flash hider).

No need to "break your action" or deviate from the normal operation of your firearm to reload.  

Loads easier than a standard magazine. No heavy spring to push each round against.

Will fully load on a closed or open bolt.

One screw installation.  No holes to drill. No need to modify your firearm.

Two minutes to install. Two minutes to remove, should you decide to shoot outside of California.

Ultra durable and heavy duty, built to last. 150% to 300% thicker side walls than most polymer magazines.

17-7 Stainless steel magazine spring.

CNC turned steel charging handle with glossy black oxide finish.

Round counter indicates exactly how many rounds are left in your firearm, including what's in your chamber.

Holds the bolt open after the last round is fired.

Allows for easy clearing of type 3 malfunctions (such as double feeds).

Can be used in California and other restrictive firearm states. Check your local and state laws before ordering.



Patented Innovation. (CompMag has 6 patents at this time.)

Designed and Made In the U.S.A.   Right here in California.



It does not, by itself, make your firearm New York Compliant. For N.Y. compliance you must either epoxy over the screw once the CompMag is installed or use another N.Y. locking device. For information on New York Compliance please read "Is the CompMag N.Y. Safe act compliant" at AR-15 CompMag Information.

In New York, often times a mag lock is installed on the firearm, which disables the mag release. The mag can be squeezed by the mag lock device if it is installed too tightly, and will result in the rounds or the follower not moving through the mag properly causing misfeeds. Always check the mag function before using epoxy on the maglock.



Compatible with .223, 5.56, .300ACC Blackout, and .277 Wolverine Ammunition.

Compatible with standard AR-15 type lowers. (M4, M16, AR15).

Compatible with other firearms that accept a STANAG (AR-15) magazine and have a removable upper receiver; including the SCAR16, Bushmaster ACR, SIG MCX, CZ Bren, SIG 556, Galil ACE, BRN180M, and Daewoo DR200.

NOT compatible with lowers that have a custom or extended magazine well (such as Seekins SP225, Sharps Bros, HKMR, and Spike's Jack). Not compatible in bullpup firearms such as the Tavor.

NOT recommended for polymer lowers.

NOT compatible with top loaders such as the MA loader or the Bear Flag Defense loader.



When tightening your AR-15 CompMag into the magazine well, be careful not to over tighten it. If it is tightened too much this will cause the rounds to rub inside the magazine and can cause misfeeds. If this happens, simply loosen the screw a bit, relieving the pressure. 

Before using, please read the instructions and watch the videos found in the recent posts section on our home page, entitled "Loading and Unloading your CompMag. Clearing Double Feeds.". This will help you better understand how the CompMag operates.   

Thank you.


 As we, and our Attorneys, understand it, this product falls within the laws as written. At this point it has not been endorsed or approved by any law enforcement agency or regulatory body within the United States, due to their reluctance to endorse any compliance products. Once contacted, the D.O.J. told us that they would not endorse any compliance products and that we should seek the advice of a qualified firearms attorney.

We then had our firearms attorneys research the topic of California compliance thoroughly and their professional opinion is that the CompMag would be deemed a fixed magazine in accordance with California Law. Letters from them can be found on our home page under "Recent Posts".

Even though we have had our Firearms Attorneys approve this product as a fixed magazine according to California law, your situation may be different. For example, putting a CompMag on a banned AR-15 or a short barreled rifle (SBR) will not make it compliant. Know your local/state laws and regulations prior to purchasing this product. If you are unsure whether or not you have an assault weapon, please contact a firearms attorney.

I found this product to be everything as advertised. I appreciated the awesome customer service from Nicole Maga and was able to easily explain the use and benefits of this magazine. As a firearms instructor in California, it’s good to know this product protects our 2nd amendment rights, and allows firearm owners / enthusiasts to maintain the originality of that firearm. Thank you for great magazine!

Written by STEVEN MATTHEW FORMAN on Sep 8th 2021

Well this worked out fantastic! Now using the AR15 COMPMAG to make compliant ARs in NY. Buyers are thrilled! No jamming, easy instructions and build! Shipping was quick and customer service is great to work with.

Great magazine

Written by Joe R. on Aug 22nd 2021

This is a great product, looks nice, it solidly built and makes it much easier to load rather than cracking open the upper and wearing out the pins. I live in Mew York, and I don’t like the idea of putting epoxy on the screw because when I go to PA I remove it to use regular magazines. Just put some blue loctite on the screw just to say you glued it and call it a day, what are they gonna do, open up your gun on the side of the road to check it? Doubtful. However; this can be used in conjunction with a mag latch which is also reversible and disables the mag release button until you take the shimmy out. So if you use both these then you are NY compliant. . But if not, the comp mag by itself is a safeguard because technically the mag is fixed and cannot be removed when installed properly.

Nice solution to a stupid problem, definitely prefer the compmag over speed loading here in New York. Works great, thank you

Compmag AR15. Ok, but not perfect.

Written by Chris VanZandt on Jun 8th 2021

Works ok, and cycles normal ammo as expected. Will not cycle blanks properly like a PMag. They consistently jam against the feed ramp of the barrel. Also does not work with ejection port speed loaders like the one from MEAN arms. Still trying to decide if it will be staying on my rifle or not.

Giving a 3 star because on some 300 blackout ammo doesn't work with mag, it gets stuck but it does work with the more expensive ammo

A couple minor changes would go a long way.

Written by Joel on Mar 22nd 2021

I love my two compmags. Install takes no time. After some minor dremel work, they are far easier and faster to load than a normal mag. That being said, one little change and a little better QC could have save me the dremel work and saved my upper receiver. The opening where you put the rounds into the side had some rough edges and it was almost impossible to load rounds straight. 5 minutes to fix. More importantly, the pin that locks the screw in place sticks out a little due to it not having a groove to make it flush with the side of the compmag. This results in it gouging the inside of the upper receiver when you close it. Again, 5 minute fix. Would be nice to not have to modify it out of the box. Small minor changes though and I love the thing!

I absolutely love mine great solution to fixed mag low capacity’s lowers it works great!

Brilliant design

Written by Brian C.Thomas on Jan 31st 2021

I was tired of trying different fixed magazine products. I tried AR Maglock, and Juggernaut Tactical. Both of those felt poorly designed. With AR Maglock I didn’t like how difficult it was to clear a malfunction. And with Juggernaut Tactical I didn’t like not having a bolt catch/release. The Compmag however is GENIUS. Your AR is not permanently modified in anyway and if you travel to a free state it is SUPER easy to remove. I highly recommend this product for anyone that uses a fixed mag setup over a featureless setup. Great construction. Great price. And great customer service!

Fantastic Product & Even better customer service

Written by Steven on Jan 11th 2021

I purchased the AR-15 magazine, and it's exactly what I was looking for. The product was easy to install and came with clear directions. It's obvious that this company takes pride in their product and its shipping and handling. After a bit of practice, I can load this magazine faster than a normal magazine. I purchased a second one for a friend who liked mine so much, but I messed up the shipping details. Nicole @ CompMag helped me out and went above and beyond to get me my second magazine. Thank you very much Team CompMag! I'll be recommending this product to all of my friends who are looking for the perfect Cal-compliant fixed magazine solution.

Ar/ak Comp mah

Written by Richard Bernal on Dec 7th 2020

Before I purchased I thought it was an amazing idea but after using it on my AR & AK I found that if you don’t have the magazine angled correctly the cartridges would move around and get stuck inside the mag. Then you would have to fiddle with it to get the bullets out. It’s more of a pain but if you get it in correctly then it’s a good addition. I will be trying out a different product.

Written by Barton on Nov 22nd 2020

Living in NY, this seemed like a viable option. Purchased the compmag, received it in a timely manner, all the way from CA......very impressed with it so far, very durable construction, and operates flawlessly, even with the full 10 rounds in it, for anyone that wants to keep their rifle the way it should be in a commie. state, yet fall within the parameters of the law this, in my opinion is one of the best, if not the best option out there.

Ar15 comp mag

Written by Marc rItter on Nov 1st 2020

Well, it makes a rifle NY Compliant. It’s a little awkward loading without it jamming, but it makes a rifle compliant if you’re in NYS. I wish I didn’t have to use it, but there are few options. When I load less than 10 rounds it seems to work better, when I load 10 it seems more likely for the rounds to shift around and jam. If you live in NY and need a fixed magazine, it’s a solid option.


Written by Christopher HiCks on Oct 20th 2020

Hate that I had to do it but was delighted there was a product that made a ridiculous law easy to manage without permanently altering my rifle. Easy to install and works as described. Would have given the product five stars if it came In different colors and the outside design wasn’t so ornate. Like my magazines simple. The bottom line, it’s the only product I’ve found that resolved a problem without too much problems.

Awesome product

Written by Jeremy Knight on Oct 19th 2020

I love my CompMag. Unfortunately I have to use this to begin with, however I'm very grateful for this product. No issues cycling, kind of a pain to load though. I found It best to have the mag at a 45° angle while loading. Otherwise the rounds like to go vertical creating an issue. I simulated a failure to eject/double feed, this mag made it very easy to clear. Overall a great product, would recommend to anyone that needs it to keep their scary "assault" features.

warning: COMPMAGs do not work with MA loaders or BF-10

Written by ROB on Sep 24th 2020

I just want to warn others that the comp mags do NOT work with either the MA loader or Bear Flag Defense loaders. This was a deal breaker for me. I really wish I had known this before purchasing. I was so confident I would love these, I made the poor choice to epoxy these before I had a chance to try them at the range... I had to hammer them out and am now back to PMAGS. For anyone working at compmag reading this, you might want to add this somewhere on the website - considering so many of us in restricted states rely on speed loaders.

Comp mag Review

Written by Jeff McDaniel on Sep 19th 2020

The thing works great and looks great. It’s a well made product and it takes 20 seconds to install/remove which I love. The only question I have and the only reason I gave 4 stars rather than 5 is what holds on that little L clip that goes over the screw? Is it really necessary? I lost one the first 10 minutes cause nothing is holding it in. I didn’t really want it falling into the inner workings of my rifle. It needs a clip or something to hold it in.

Compmag for 300 blk

Written by Thomas Schwallie on Sep 15th 2020

Written by michael on Sep 1st 2020

This product works great, if you live in a commie state like me. Reliable, affordable and fast shipping, what else could you ask for other than for your rights not to be infringed upon?


Written by William Caughell on Aug 24th 2020

I'm going to be honest, I hate that this product exists. But if you live in the State of California and own an AR-15, this is a great option. I was not excited about getting rid of my “EVIL” pistol grip, collapsible stock, or flash suppressor. That’s a lot of responsibility. Where would I put these items after they were removed from the rifle? Would they still be EVIL at that point? Would I need to put them in a separate safe or could I trust them to be stored in my safe with the rifle. And if I threw them away, what if they managed to make their way onto another rifle where they could be evil once again? It was too much stress to think about what these evil items could do if I allowed them to stay evil. Then I found the CompMag. This item is like having a prison guard on your rifle. It tames those evil features and reforms your rifle back into a law abiding rifle. It only takes a minute to install, and it is very well made. Loading took a little getting used to, but it beats some of the other options out there. And if the laws in California ever change back or I flee the state, it can be removed with a screwdriver. Best of all, it looks like a 30 round magazine, so my rifle does not feel neutered.

The CompMag is a good system to use to ensure your modern-sporting rifle is California-compliant with minimal divergence from what makes an AR-15 an AR-15. I recommend this system over all others.


Written by John on Jul 12th 2020

Excellent product, kudos for the design that allows us to be legal in the people’s republic of NY. Hell of an idea! No more having to break open the action every time you have to reload and wear out the receiver holes with the steel pin making it sloppy. Faster reload time and sooner back on target. Works well and appears sturdy so far. Recommend it to those stuck in the DemoRAT controlled anti 2A states!

works fine

Written by Miklos on Jun 28th 2020

I like it. Installation is easy and the device itself works well. I also like how the actual size of the CompMag closely resembles a 30 round mag so the gun doesn't end up looking too neutered. Believe it or not, I think this also makes the gun a bit more "range friendly" so-to-speak when shooting with friends and family because there is no compulsion now to go through the whole 30 round mag. Just pop in what you want and shoot them off.

Perfect for us behind enemy lines

Written by Paul on Jun 18th 2020

Compmag is great if you're in a restrictive state. Makes it so you don't have to split your receivers to reload your magazine. The only downside is that you have to be careful when loading the compmag. Sometimes rounds go up and get stuck and it's a real pain to get out.

Great product for fixed mag kits

I spent a lot of time doing research on the best option for a fixed magazine build. This product is exactly what I was looking for. It is a bit costly, but it is worth the price. It is built strong, sturdy and has a solid and firm feel in the receiver. It pays for itself with the money you save on buying speed loaders for other fixed magazine builds. loading is simple, and can even be fast depending on how you train. I recommend this product to anyone looking for a fixed mag kit. Skip the other conversion kits and spend the money on this.

Written by Peter on Sep 27th 2019

I've had the compmag for over a year now and today was the first time I've taken my ar out to test this setup. The mag is of high quality, very solid. When I first got it, just manually cycling rounds at home, it had feeding issues and with rounds getting turned all over the place in the mag. I was worried but since trying it out at the range actually firing from it, it performed flawless!! I actually couldn't believe how good it was, fed every round, not a single malfunction from the get go! It was also very easy to load, easier than loading a regular magazine actually cause there is no spring tensing when loading. For the range, this is almost just as good as regular 10 round mag cause of how easy it is to reload. Only thing negative is it does not hold the bolt open on the last round. other than that, it's a great solution to our restrictions here in CA. Oh, I also love the fact it's easily removable, just one screw/plat holding the mag in place, no modification to the gun at all.

Not bad, could use some revision.

Written by Chris on Sep 24th 2019

This one of my favorite solutions for CA compliance on range only rifles/pistols or for distance/accuracy focused rifles that don't require fast reloads but need to maintain semi-auto function. Solid concept but I would like to see better plastic or even a steel bodied version. Lastly, although minor, the mag itself has a poor aesthetic and could definitely be made to look better. Fake screw heads? No Thanks. Overall I'm very pleased and am excited to see what Compmag does in the future. A five-round hunting model is something I would definitely buy.

Doesn’t feed - customer service unresponsive

Written by Michael lembo on Aug 20th 2019

I purchased the AR-15 version and the AK-47 version. The AK version was installed by a licensed gunsmith/FFL. I installed the AR version myself, meticulously following instructions. Both versions only accept 6 rounds (supposed to accept 10), and neither of them feed any rounds. Huge waste of money. If customer service were accessible/responsive, this negative review could have been avoided.

Do not oven cure!!!

Written by DAN on Aug 7th 2019

I truly LOVE the concept! After a little filing it functioned well with 300 Blackout. HOWEVER ... Despite claiming to be made out of a pretty heavy duty polymer/fiberglass, it seems you can not oven cure these mags after cerakoting, as ive done with many other magazines. After doing so the mag appears to have shrunk!!! Upon trying to reinstall the internals I found the mag tolerances to be so tight that it will not feed rounds. The follower can barely make it back to the top of the magazine without assistance.

Ca 556/223 compmag

Written by Erich Walker on Jul 18th 2019

Great product, best solution so far for range use AR in restricted states. Compatible with other fixed-mag solutions, so if you have already modified your mag release to current standards (like I did) you can still use Compmag to gain jam/double feed/make-safe capability. I still can’t drop the mag in a malfunction, but I can drop the spring tension, which is the next best option. And the side loading gate makes reloading or de-loading simple & safe. And no permanent alterations to the rifle. Take it all out with a screwdriver. 10/10. Mag itself is easy to disassemble. Built like a tank. Very pleased.

Written by Mark on Apr 20th 2019

Installation is relatively easy (the micro retaining pin can be tricky). It will require some “force” to fully seat the replacement magazine. Loading is an art that takes practice.

Great product to meet the CA laws

Written by Myles on Mar 27th 2019

I purchased the CA CompMag-AR15. I waited a couple months for the new CA version to be released and it did not disappoint. It was easy to install and worked exactly as advertised. The magazine is really snug to fit in and you have to pull it a bit harder than I expected to eject it when loosened, but once in and tightened it is in there firm with no chance of unexpected ejection if you hit the mag release. It is well built and I had no issues loading, unloading or firing using it. Just make sure to follow the loading video. Great product overall and would buy again.

Compmag review

Written by Dan on Mar 11th 2019

So i ordered the compmag because I didn’t want to alter my weapon. Good ol Comifornia doesn’t make it easy for us gun owners and this was the perfect thing that would bring me into compliance. The installation was easy and straight forward and it’s made really well and is very solid feeling. The only complaint I have is with the mag installed the rifle won’t fit into its case for transporting it to the range and it doesn’t fit into my safe very well (my safe is kinda small). Other than that I would recommend this MAGAzine to anyone who doesn’t want to mess with altering your firearm. A+ Comifornia compliance product

Amazing product

Written by Kevin on Oct 31st 2018

The CompMag is a game changer in my opinion. I kept trying different compliance solutions (both featureless and fixed mag) and nothing felt right. It always felt like a compromise. The along came the CompMag and everything was right in the world! I was able to keep any features I wanted on my rifle and I didn't have to worry about increased wear from excessive use of the takedown pin. Although it wouldn't be the best solution on a home defense rifle, it is absolutely perfect for use on the range. Thank you for making such a great product!

Great Concept!

Written by Cory C on Sep 5th 2018

I bought a Compmag to use in conjunction with a Cross Armory Maglock because the standard screw and plate system isnt NY compliant. I could have gone with just the Maglock but after researching the Compmag and seeing that it was so much easier to reload and also to be able to clear double feeds. I bought it simply for ease of use and safety. It is extremely well designed and well built, it far surpassed my expectations and will be a part of any NY compliant build Im a part of.

Awesome alternative. Flawless. Used full 10 rds or 2 rds at a time. Easy install and reliable. Would definitely buy again. Used it on a target rifle.


Written by Jason A on Aug 11th 2018

Recently got a CompMAG and very happy with it. I was using another device that required me to open the AR-15 action, which totally sucked. But I wanted to keep the AR-15 look. This CompMAG really fit the bill... took 20 seconds to install, and actually looks very nice on my AR. Its slightly bigger than a 30 rd mag. The slide-open door is great, just drop in 10 rounds and you are good to go. The price is reasonable as well. But i especially like that its a 'locked' mag so I get to keep my AR-15 look, but easy enough to take off when I visit NV, AZ, UT or other gun friendlier States.Just an idea for the owners of CompMAG, but like with chamber flags (many colored orange) it would be nice for the bottom of the CompMAG (the plate that holds in the spring) to maybe be orange (as an option) so that it can easily be identified as a CompMAG locked mag instead of a 30 round mag....just so the Range Officer will know its a locked CompMAG and they're not going to go to your shooting station to inspect your rifle and check that its not a 30 rounder.

compmag for the ar15

Written by Rick Holton on Jul 25th 2018

With the never ending BS gun laws in California this is a great fix. Very easy to install, I like the fact that I didn't have to change out anything and the Compmag looks better then the normal 10 round mag. Showed it to my buddy, he got one also.

fixed mag compliance

Written by Marty Ray on Jul 24th 2018

If you are a CA owner of an AR the nicely made CompMag device lets you easily turn your AR into a CA legal (for now!!) fixed mag weapon with only 10 rounds, that avoids you having to remove any other "evil" features that are on your AR. It's easy to install, and easy to remove when you finally achieve that dream of moving to a red state that takes freedom seriously. It is easier to load than a regular P mag or other mag. What's more, the end result of installation looks even more "evil" to leftist wimps than your old short 10 round mag, yet it only holds 10 rounds. Looks like a banana mag holding 30-40 rounds, ha ha. Course, this look might lead you to have to explain yourself, but I think that having any AR these days in this state may place you in that position. To defend against this, I chose to laminate and put into my AR case, the CRPA flow chart that shows what is legal and what is not. You could do all sorts of other things to legalize your AR, such as removing all "evil" features, having a weird looking stock, turning it to rimfire, or even registration if you think that's a great plan, but the CompMag is quick, easy, reasonably priced, easily reversible, and it sure seemed like a great plan to me. It's well made and parts are available.

Your product is Awesome!!!


Written by Robert C. on Jul 17th 2018

Okay, so I’m a bit of a procrastinator, on the Wednesday before the July 31st Assault Weapon registration deadline here in California I was looking for an answer as to how to ensure that my AR-15’s were California Compliant so that I would not have to register them as Assault Weapons. The answer, CompMag. I ordered three magazines and they arrived two days later. On Saturday morning I installed the fixed magazines on my LWRC, COLT and S&W rifles. It took more effort to get the rifles out of the safe then it did to install the magazines. Simple and easy and a great fit. Operation so far has been perfect. Get a Compmag, be compliant, obey the law.


Written by Ron Koss on Jul 17th 2018

California stinks. I tried featureless with a Megafin but hated it. Juggernaut Tactical is interesting but I didn't like the position of the button since it interfered with the safety lever. Plus there are other issues. The Compmag turns your rifle into a range-gun, and you have to be careful loading the cartridges since they may turn 90 degrees in the mag (before you release the follower) and then it's a little pain to clear. But, (1) it's a simple yet ingenious device that's easy to install, (2) I'm confident it's legal, (3) I can keep all my evil features, (4) if I go to a sane state, like Arizona, I can easily remove the CompMag and quickly have a real rifle again. - I'll give the CompMag five stars because it did what I expected it to do.

It's a shame that I need to use a device like this to keep my "evil features" in the loony state of CA. That being said, this is an ingenious creation.

Written by Riley Pippen on Jul 12th 2018

In the beginning of using the comp-map, I was laying rifle down bolt release side up; and while loading the mag I noticed a round or two woyld fall into a verticle crease and could only be removed by seperating the upper and lower receivers. After some trial and error I just started holding the rifle with my dominant hand at a 45° angle and load rounds that way. Haven't had any issues since. BS California laws but this is a good product to get around liberal craziness.

The Compmag works well. It's very easy to install It shoots ten rounds every time. The only downside is that it usually doesn't lock back after firing the last round. I've talked to others that have the same problem. It's a problem without a solution but I've decided to live with it.

Written by victor on Jul 8th 2018

First these are very well made, I also like the fact that i can load my rifle without opening the rifle. Next in the state of California if you don't have the mag in you must take everything off and add after market items to your rifle, can you imagine go in public with a rifle looking like that or even combat ya right California. But i will be ordering more for my other rifles next month. So all that being said I must thank Compmag for coming up with a great ideal.

Compmag review

Written by Mike on Jul 1st 2018

The compmag is a great option for California’s fixed or featureless rule. It allows you to still have all the “evil features” that these democratic snowflakes hate (please vote and get these a$$holes out of California and make Cali Great again, haha). For me, the looks of a firearm is very important and the compmag allows me to keep the looks of my firearm. The only thing you really can’t do with it is a speedy reload but if you are not planning to use it in competition or three gun or anything that makes it mandatory to reload quickly then I would use highyly recommend it. I only shoot for target practice and I can take my time so I really don’t need a different option. Just my two cents. :)

Ever since California pass the new laws regarding our rilfes. I have looked into every ways to comply. ......registration is not an option. I tried the AR mag lock. It was cool but ran into problems with double feeds . Which was a pain in the butt to fix, not to mentiontime consuming . I went Featureless on one of my rifles . But I saw a review on you tube "AR-15 CompMag" . I had very positive feedback. This was very easy to install and use is very reliable. I have yet to experience a double feed or a jam that did not require disassembly . Very reliable , easy to install, and easy to load (with some practice /retraining ).I would recommend this method of going the magazine lock route .

I just installed the CompMag on my two ARs. What an ingenious solution to the restrictive California assault weapon registration laws. It gives the State what it wants, and allows most recreational and sport shooters to use and enjoy their ARs while still keeping the adjustable stock, pistol grip, muzzle break, forward grip, etc. It's easy to load and unload the magazine, and you don't have to wear out your rifle by constantly opening and closing the action. It takes less than a minute to install, and everything you need to do it is included. A 5-Star product! I would love to see a second optional version of the CompMag with the cartridge loading port on the opposite side.

This fixed mag will also save a lot of excessive wear on my AR-15 since I do not have to constantly open the breach to load. This is by far the best solution to having your AR-15 California compliant.

Excellent product to have when you want your AR-15 to look like a AR-15. Easy installation and loading / unloading. And yes, I have purchased the other type loaders, and feel this product is the best. Price of AR-15 CompMag is reasonable, being you have to buy a loaders and pin , which is hard to uninstall, if you wish to go shoot your AR-15 in another state. With other loading devices, you have you cycle the rifle to unload your gun or drop the bottom of the pinned clip. Very awkward. I have purchased several for friends and family and they all are pleased with the product too. Finally, it looks great in my AR-15 too.

Trying to comply with California's gun laws can be a challenge so when a high quality innovative product comes out to help us keep in compliance it is something to have. The Compmag 10 round capacity magazine is very innovative in that you do not have to break the gun apart to reload it. The side door and magazine latch with a counter on the magazine is user friendly and safe. I am looking forward to seeing more great products from Compmag

Compmag/Customer service

Written by Tom C. on Apr 11th 2018

In CA, the CompMag is a great alternative for a fixed mag solution. The magazine is solid and should provide prolong use. Besides developing a great product, their customer support is top notch. I had some function issues with my first order of CompMags. Contacted David and he provided excellent support in resolving the issue. Once he understood the problem, he immediately took care of the situation. CompMag takes their products seriously and believes in providing positive customers service. I would definitely recommend the CompMag to anyone trying to avoid registration and/or not big on the idea of having to separate the upper from the lower to release their magazines.

AR-15 COMPmag review

Written by Jonathan H on Apr 7th 2018

Chose to go the Compmag route for a fixed-magazine, mainly because of the problems when clearing a jam with the other fixed-magazine solutions. With the Compmag you just lock down the follower, which takes pressure off the rounds, and you can clear the jam as you would on a "normal" rifle. Also have some concern over the wear around the pivot pin if I had to open the action every time I had to reload. Product appears to be very well made. The plastic magazine body is thicker than I expected, and very stiff, so I expect it will be very durable. The sliding cover, spring, follower, and handle to lock down the follower are all similarly well-built. It's hard to imagine you could improve much on this for a fixed-magazine conversion.

I found it is easy to use and install, It Works for all .223 & 5.56 based Cases, it is a bit shorter than some magazines in respect to overall Cartridge length, but a person could open the face of the magazine with a simple dremel tool to gain more length for some wildcat cartridges based on the .223 case, I will not work with 7.62x39 or 6.8spc and a host or other cartridge wildcats based on the .shortened .308/7.62x51 cases or the .458 or .375 socom. If I could get the magazine open it could easily be modified for those wildcat ar15 cartridges. The compmag does what it says it will do and allows a person to have an attached 10 round magazine that can be locktighted into place with one siple allen head cap screw.

Compmag ar15 Review

Written by Jim Clark on Mar 31st 2018

CompMag is a nice piece of engineering, as well-conceived and well-implemented as your AR itself. Our CompMag installed quickly and well. Cycled through over 100 rounds without fail or need for adjustment (Stag Arms). The loading port and counter are handy. The installed look and feel are familiar and comfortable --- and provide a satisfying sense of putting a thumb in the eye of the pandering morons in our government.

The mag functions perfectly. Easy to load and unload. Sure would like to see a five round mag that is shorter and more compact for those of us who use our AR's for hunting.

Easiest fix I found out there to make an AR CA compliant. I give it 5 stars overall.

So I just did a review about this and gave it a 3 star because I was having trouble with my weapon jamming when my mag had 5 or less rounds left. Well comp mag has got back to me and I’d like to report that they are sending me out another one. The customer service is excellent and honestly that’s everything when it comes to sales. They helped me out without dealing with any B.S. I recommend this product to everyone here in Buffalo NY. Thank you again Comp Mag

I am impressed with the magazine. Good design and construction, performs as expected of any quality magazine. Installs very easily and with no modification to the lower. Yes, it's pricey but as said about the design, quality and performance standards are there so for me it was/is a good purchase.

AR15 Mag

Written by Chris Patrick on Mar 19th 2018

I really like the idea of this product. I prefer to run all the features on my Ar and this appears to be the way to do so. It installs easily and actually looks better than the 10 round mag us unfortunate california residents have to use. I would and have recomended this mag.

A very easy process to install. Great fit a a good spring to feed rounds. Loading the rounds was easier and not as clumsy as I thought it would be.

Hands down the best way to make your rifle CA legal, super easy to install and use.

Worked as advertised, loads easy, no feeding problems, bolt stayed back after last shot. I would recommend to anyone who wants to keep their pistol grip, flash hider or adjustable stock. Big thumbs up on a fantastic product. . .

WOW do not have to remove my evil features!!!! Ordered one for each of my ARs. Works flawlessly!

Your mag kicks ass!

Your mag kicks ass! I installed one on my dads ar15, it’s easy to install and worked very well. We ran 300 rounds through yesterday without any issues. You’ve made ar15’s great again for us folks in California. You’ve also made another several customers since there were a bunch of people checking it out at the range. We will be ordering more for our other rifles. I am very much looking forward to the AK version. I will want to get one as soon as they are released. Thanks for making such a great product!

Just put 500 rounds through your mag and it's the best CA compliant solution .. so far it's also the only compliant device that makes feeding issues a breeze to clear. I would like to carry a couple of your mags in stock in my shop for my customers. Again I appreciate a good product that actually functions .. thanks
