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.

Reversible 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.

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.)

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

HOW DOES COMPMAG WORK?

(By David Maga)

What we have done at CompMag is found a way to help Californians comply with the stricter California laws. SB 880 and AB1135 passed in 2016 outlawing the bullet button that has allowed us to keep our firearms compliant. We needed a good solution to this problem. With the threat of having to having to register our firearms as "assault weapons" on the horizion, and after many long months of designing and testing, we finally we found a way. The CompMag.

The CompMag is the ultimate fixed magazine solution for your firearm. Even though the magazine is fixed into the lower receiver, it still allows your firearm to be very easy to use. The CompMag can be loaded through a door in the side while still in your firearm. Loading is easier than with a standard magazine and there is no need to modify your firearm. The CompMag has an internal locking mechanism that locks into your firearm with just one screw. Super easy installation. No holes to drill.  It can also be easily removed by opening the action and removing the screw from the inside. This allows you to have your fully functional firearm back. This is useful if you are going out of state to shoot or you live in a state other than California. While in California, keep it screwed in at all times to be compliant.

Having a fixed magazine allows you you to retain all the other features that we love: a pistol grip, a retractable stock, a forward stock, a thumb hole stock, and a flash suppressor. The AR-15 CompMag can also be used in other restrictive states. Check your local and state laws to see if the CompMag is right for you.

Loading the CompMag couldn't be easier. 1. Retract the spring and lock it. 2. Slide the loading door down. 3. Load the cartridges in. 4. Shut the door. 5. Release the spring. You are ready to fire.
