When tightening your AR-15 CompMag into the magazine well, it should only take about 2-3 complete turns of the screw to lock it in. If it is tightened too much this will cause the rounds to rub inside the magazine. If this happens, simply loosen the screw a bit, relieving the pressure.

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
Often the best ideas are the simplest. Easy to install and worked like a charm!
Super Product,un-matched design,love this Mag!!.
It is fantastic, simplest solution to Calif. Problem, at least one of them
Best solution to being complient. Can install in less then two minutes.
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!
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.
Great product can't wait to buy one for my AK
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.
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.
Well built using durable materials. No feeding or ejection issues. Easy to load with just a little practice. Very easy to install and remove and is a brilliant solution to the oppressive laws in California. I would not hesitate to recommend the AR-15 CompMag.
A simple yet elegant solution for California compliance. Easy to install, works flawlessly! Full disclosure: The only drawback is my AR's with optics and this magazine no longer fit into my soft cases. No big deal, I'm over it!
Very well made product, easy to install and works flawlessly.........
Simple and effective way to legalize your AR-15, doesn’t require making major changes and lost or misplaced parts.
I’ve used the Compmag once since received it a couple weeks bit worked great. Think I might get another one.
Haven't had the chance to take to the range yet. Functioned without problems in my shed with live ammo. Would like to see an AR-10 version and one for 300 blackout. I've shared the web site with a bunch of online buddies, they all seem interested too.
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.
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.
Works flawlessly. Every function of your AR is retained. A little pricey. But it beats modifying your rifle. I have recommended these to my other shooting buddies. They love them. Definitely a good and simplistic way to deal with our idiotic laws.
I’m gonna be brutally honest I don’t like having to have this product at all. With that said out of all the high price cali-compliance products out there this is the best and the price is great too. Thank you guys for your innovation to keep me shooting and defending myself.
The AR15 Compmag is one of the best idea's to date for making your AR California compliant, I am just waiting to see if there will be a Compmag for AR10's.
Ordered a pair of the CompMags and had an issue with the USPS and non delivery... Sent an email to CompMag explaining the situation and inquiring about alternate shipping options if I needed to reorder the mags. Within 10 minutes I had a response with a possible explanation for the situation as well as a guaranteed fix if the situation did not correct itself. Thanks David! You and your company Rock! P.S. Your product is Awesome!!!
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.
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.
I have tried many products to be California compliant and rhis has been hands down the best product i have used. I will be buying again. Cant wait for the Ak mag to be released.
Very nice , no modifications needed to my AR . Just insert and lockdown with a screw .
Fast delivery. Easy installation. Roughly about 10 Minutes or less. Works great on the range.
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. My only complaint is that the rounds in the mag are a little loose, and they rattle around a bit. Easy installation, easy removal for when I go to another state with "normal" laws.
The mag worked great way better then I was expecting !
Good quality mag. I would like to see, if there will be an option for loading mag on right side. But that is only preference thing. Is only thing i gave 4 stars. Ether way im waiting for AK mag to come out.
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.
Great magazine for us in California and any other states that have added laws limiting our guns and ammunition. Easy to install, simple to use, well made and designed. Put it in a few minutes with tools and materials that were supplied by the manufacturer. Great customer service and a good company to do business with.
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.
installed 2 comp mags on my AR 15 guns. installation was quick, with no fitting or problems. I would recommend them. Can't wait for the AR10 mag to come out.
I bought this motherfucker because I live in a commie state . And they don’t know how to respect people’s rights . So thanks to this amazing company my Ar is now not a “assault weapon “ anyways it’s a cool magazine. Easy to install and use . Looks good and feels durable and honestly I like it a lot !
I was told about the compmag by a friend and needed to make my AR legal. It took only 15 seconds to install and if you go out of state you can take it out If you live in Comyfornia and need a Awesome easy way to be legal go with compmag. You will not be disappointed.
The compmag serves its purpose and does it well. Kudos to American innovation and made right here in California. Simple, effective and very well made. Thanks for a great product that accomplishes the needs of those California shooters. Will definitely be using this setup for the range.
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.
This is a great product. Made my AR California legal. Very easy to install. Can hardly wait until there is a CompMag for my AK.
This magazine is a great solution for CA AR-15 owners. It is extremely easy to install and very easy to load and reload when shooting. This was my favorite of all the CA AR-15 compliant kits that I purchased. I can’t wait for the AK-47 version to be released.
So far looks and functions great. Loads easier than regular magazine. Great alternative to the other systems. Albeit a little pricey. It does save some money over other alternatives. Would recommend to others looking to comply with our ridiculous laws here in the people's republic of Cali.
magazine arrived on time and in great shape.i have no complaints, your product is solid and works just like it should. There is one thing i would like to leave as feed back. i wish the magazine was backwards, i wish the loading window was on the right side and the spring handle on the left. i am primarily right handed and i like to load with my right hand so i would find it easier and more convenient to tilt the rifle left and load with the right hand. just a thought.
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. :)
Best option for the new California laws. I do not agree with the new laws, but being a father of 3 young kids, this is the best option to comply with these silly rules.
Excellent quality and easy to install and hopefully when it's legally allowed uninstall. Easier to load than a typical P-mag too.
They work great
Nice compliance device. Wrth the investment. Easy and quick to install. Highly recommend. Looking forward to the AK Mag.
I cant be more pleased with this product, very easy to install, build quality feels fantastic, easy to load and keep your rifle CA Compliant. Customer service was outstanding 1st unit i recieved had a defective spring, i messaged them same day, the sent me a brand new mag got it within 2 days i believe. Great Product!
Buying this product totally changed my life. Thank you
I genuinely recommend the Compmag! It's the best California compliment attachment you can purchase for your AR in my honest opinion! Practicality- 5/5 Aesthetics - 5/5 Innovation- 5/5
Great idea, and the magazine is sturdy and works very reliably. Very simple, yet very innovative. Thank you compmag designers. I hope that in the future you make magazines for additional firearms (AK, SCAR, CZ scorpion, Sig MPX, etc). I’ll definitely be buying a bunch if you do.
This magazine is amazing! It’s simple to load, rounds cycle great, and most of all I don’t have to crack my gun open to make it CA legal! Easier to load than a regular magazine, and simple to install! I reccomend this for all these rediculous CA restrictions! I’ll be buying more!
This is an outstanding product. I fits and functions flawlessly in all my AR platforms from my Colt 6920, Bush Master and all my Frankin ARs I have built through the years. In addition it also is being used in my SCAR 16. I look forward to the soon to be released COMPMAG for my AK platforms.
Makes the rifle CA compliant. Let's you clear malfunctions without disassembly of the receivers. Quick minimally intrusive install. No modifications required. Set it and forget it. Happy with it. Would recommend to anyone not wanting to uglify their rifles by going featureless.
Happy with the product, feels solid and works well. Support responded to my questions quickly. Glad to be keeping my features (for now anyway :-)!
Pure genius! This is the answer to the California fixed magazine mania. Easy to load and, more importantly to me, render the rifle safe in all conditions. I'll buy another. Definitely worth the price!
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 .
Definitely the best option I have seen to make an AR a fixed mag platform. So far I have put around 500 rounds through it and it has worked as advertised.
Haven’t taken it to the range yet so no review of function. The idea is genius, the construction is solid, the installation is easy and shipping was very fast. So far I'm very impressed by this product! I’ve recommended it to my friends and family, and plan to buy more.
The best option for fixed magazine for the AR platform. Easy to install the comp mag and no problems when shooting. 5 Star product
If you are forced to live in California and still want an AR15 you need this magazine. Simple to install, well built and works brilliantly. The ability to clear a double feed puts this soltion ahead of pack in my opinion. I highly recomend this product.
This is my favorite Magazine! Wish they made more calibers
The comp mag works perfectly! Easy to install and easy to load. I'd definitely recommend this magazine!
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.
I have 8 of these----Need i say more
After a friend told me about this mag. After installing on my AR-15, makes it California compliant without having to remove all my nasty features. The easy of reloading is now much better. 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. IF I decide to take my AR-15 out of Ca for a shoot, I just simply remove the mag with a hex wrench and slap in my regular mags. Great product, excellent quality materials
well worth the money! it's CA compliant, super easy to install and remove. Will buy again for my other ARs
works great easy to instal and to use and easy to dismount as well one of the only mags u will need in order to stay Comufornia Compliant
Excellent product! Quality is Excellent and cust Service second to none. I intend on buying at least 10 more for all my guns. IMO it’s the best and least obtrusive way to comply with the ridiculous new California laws. Can’t wait for other gun options. Eric
Fast shipment and the packaging was neat. The product was good quality and it was super easy to install.....I was satisfied on all levels...Thanks guys.....I highly recommend this product guys....I never write reviews but on this product I had to
Bought this for my first AR build and to be as NY compliant as I can, I know that it hasn’t been confirmed NY compliant but between the epoxy and an added set screw for my mag release (which is also epoxied), it’s not coming out of the lower anytime soon. Super easy to load, works like a charm, and looks good too! If you live in a restricted state and want an easy loading system, this is it.
Best route to take if you live in Cali. Very well made, shot a good amount to say it’s reliable meaning I haven’t gotten a jam yet which is good. I would recommend it. Easy to load and unload
This product did what it says it does! It was beyond simple to fix the magazine with a simply removable bolt! Why modify your receivers when this does the job without! Worth every penny! Considering another one for my other AR!
Purchased this mag awhile back to make my AR-15 California complaint it was a perfect way to do it . Installation was a breeze, loading is also a breeze know I won't have to register my AR as an alsult rifle now I would recommend this product to anyone who wants to keep all the bells and whistles on their AR....
This device rocks I've tried all three of the other ones and this one is the easiest simplest safest product you can use to make your AR California compliant
Product works just as described, and looks amazing on my rifle. The loading is not too complicated, but definitely takes some practice to load quicker. The best part is it makes my rifle CA compliant.
I have tried various ways to make my AR compliant with the ever changing CA laws. But this one seems to work just perfectly. I have used features on some of my build but I also want to keep my pistol grip and UBR on one of them without having to break down the action. This invention is a genius work. Easy to load ammo with the sliding side door on the mag. With this, I can keep the so called evil features while keeping my AR look like a normal AR.
I WOULD LIKE TO CHANGE MY REVEIW FROM ONE STAR TO FIVE STAR. I WROTE A POOR REVEIW ON THE PRODUCT BECAUSE IT WOULDNT WORK WELL IN MY GUN. THE COMPANY SENT ME A NEW ONE WITHOUT ME EVEN ASKING FOR A RETURN. THE NEW ONE FUNCTIONS FLAWLESSLY, EVEDENTALLY THE FIRST ONE HAD A FLAW. THATS WHAT I CALL CUSTOMER SERVICE. I WOULD RECOMEND THIS PRODUCTTO MY FREINDS. THANKS COMPMAG FOR AWSOME CUSTOMER SERVICE. AR15 SFI TACTICAL.
Great product , great quality. Best alternative to Ca compliance. Almost no alterations but adding a single screw and lip. Only downside is that It won't fit lowers that aren't full mil-spec. Like the Sharp bros lowers. Five star rating for sure.
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
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.
Magazine is great, fits perfectly on my wife's Anderson Manufacturing Lower, but it will not fit in my Seekins Preceision SP223 Lower, so beware if you have a Seekins lower or a longer magazine well as this magazine will not fit.
Wonderful product works like a charm and can’t wait to see the ak model mag
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.
The quality of the mag is excellent easy installation. Easy to load and unload. I really like it. Messed up in California to know have to have a fixed mag,but honestly using this mag is way better than having to open your ar-15 every time to take the mag out using the mag button locks. This mag makes it easy to load from the side. Best way to go to be California compliant with your ar-15.
Comp mag worked great in my WIndham Weaponary (Formerly Bushmaster) but for some reason would not work in my PSA kit. My brother and I came to the conclusion that it was my feed ramps on the PSA kit. Customer service (David Maga) was awesome, very helpful a great asset to your team.
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.
PERFECTION... can’t explain how amazing this is and how easy it is to use install and ZERO malfunctions.
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.
Great product! Easy to install. Great customer service and I had questions.
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.
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! 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
