The AR-15 CompMag. 10 Round Ca. Version. (price is for one unit)

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.

Fixed installation methods are provided to let the end user determine how they wish to modify their magazine.

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.   

No pins to pull out. No fumbling with extra parts.

Eliminates the need to carry around a loader.

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

Will fully load on a closed or open bolt.

No holes to drill. No need to modify your firearm. One screw installation. The screw threads into a metal insert that is molded into the magazine.

Two minutes to install. Less than one minute to remove should you decide to shoot out of California.

Constructed of impact and crush resistant, G.F. Nylon 6.

150% to 300% thicker side walls than most polymer magazines.

Ultra durable and heavy duty, built to last.

17-7 Stainless steel magazine spring.

CNC turned steel charging handle with glossy black oxide finish.

Compatible with standard AR-15 lowers. (M4, M16, AR15). NOT compatible with lowers that have a custom or extended magazine well. (such as Seekins SP225, Sharps Bros, and Spike's Jack.)

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. (Bolt catches and their machined positions in the lower vary. This feature is compatible with most combinations.) Even if this feature is not compatible with your set up, the AR-15 CompMag is designed so that the bolt carrier group will not contact the follower when the magazine is empty.

Allows for easy clearing of type 3 malfunctions (such as double feeds), due to the fact that you can easily remove spring pressure from the magazine and simply slide the round back into the magazine.

Will accept both .223 and 5.56 ammunition.

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

Patent Pending Innovation. (CompMag has 4 patents pending at this time.)

INCLUDES EVERYTHING YOU NEED:  One complete AR-15 CompMag, mounting screw (plus an extra one), stainless steel mounting plate, Bondhus allen wrench, and Vibra-tite thread locking compound.

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

 

READ ALL INSTRUCTIONS:

Before using, please read the instructions and watch the videos found in the recent posts section on our home page, entitled "Loading and Unloading the AR-15 CompMag. Clearing Double Feeds.". This will help you better understand how the CompMag operates.   

Thank you.

COMP-mag

Written by Steve McDonell on Jul 12th 2018

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.

Fucking amazing

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.

Fantastic device

Written by Jeff on Jul 8th 2018

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.

review of compmag

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.

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.

AR15 CompMag

Written by Jesse Valladares on Jul 2nd 2018

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.

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. :)

Best Fixed magazine on the market

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!

Written by Luis Morales on Jun 11th 2018

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.

Great product, responsive support

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!

AR-15 CompMag

Written by Norman Lew on Jun 5th 2018

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.

CompMag review

Written by Doug ODwyer on Jun 5th 2018

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.

The comp mag works perfectly! Easy to install and easy to load. I'd definitely recommend this magazine!

best solution

Written by Kenneth MacLeod on May 30th 2018

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.

AR-15 Comp Mag

Written by Patrick Sullivan on May 29th 2018

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

great product

Easy to install, smooth as butter

Written by Ryan on May 7th 2018

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

Purchased this mag awhile back to make my AR-15 California complaint it was a perfect way to do it .

CA compliance mag that WOrks

Written by Ronald J Mulligan on Apr 29th 2018

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.

very happy

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.

AR-15 CompMag reveiw

Written by Tim Gee on Apr 18th 2018

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.

Comp Mag review

Written by Russ Clifton on Apr 11th 2018

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.

Written by Paul West on Apr 6th 2018

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.

Compmag review

Written by Daniel Degraffenreid on Apr 3rd 2018

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.

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

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
