CompMag AR-10 Fixed Magazine

Installs and operates the same as our AR-15 CompMag.

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

8 Round capacity.

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-10 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.

NEW YORK COMPLIANCE:

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.

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

COMPATIBILITY:

DPMS/SR25 compatible.

Compatible ammunition:  7.62X51 / .308 / 6.5 Creedmoor

Compatible with standard AR-10 type lowers.

NOT compatible with lowers that have a custom or extended magazine well.

NOT compatible with LMT MWS or H&K MR 7.62.

READ ALL INSTRUCTIONS:

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.
