The AR-15 CompMag.  

Price is for 1 unit. 

CA. Compliant.  

N.Y. Compliant with the simple addition of epoxy over the locking screw.

Lifetime Warranty. If something ever breaks, we will replace it.

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.



Patent Pending Innovation. (CompMag has 6 patents pending 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.



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; such as the SCAR16, Bushmaster ACR, SIG MCX, CZ Bren, SIG 556, 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.



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.

    COMP MAG AR-15

    Works exactly as described. Only wish it came in a S&W .22 LR AR PISTOL MAG and other .22LR PISTOL MAG variations.
