CA. Compliant.

N.Y. Compliant with the simple addition of epoxy over the lock cover.

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

10 Round capacity.

Newest Version. GEN.3 (updated February 15, 2021)

Instantly locks into your firearm. The CompMag can be easily removed by breaking your action, removing the lock cover on the magazine, and pushing out the mag with the release tool. The release tool is included with your CompMag.

The GEN.3 CompMag automatically locks into your firearm once it is inserted.

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.

Instant installation. No holes to drill. No need to modify your firearm.

Very easy 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 7 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 the release hole cover once the CompMag is installed, or use another N.Y. locking device. 

In New York, often times a MAG-LOCK is installed on the firearm, which disables the mag release. The CompMag 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 CompMag properly causing misfeeds. Always check the mag function before using epoxy on the mag-lock.


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

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

For receivers with Cerakoted magwells we recommend using the GEN 2 or simply roughing up/ removing the Cerakote inside the magwell where the locking wheel sits when the CompMag is inserted. You can easily do this with a bit of sandpaper.

Compatible with other firearms that accept a STANAG (AR-15) magazine and have a removable upper receiver; including the SCAR16, Bushmaster ACR, SIG MCX, 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 as you cannot separate the receiver to remove the CompMag.

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