CompMag AR-10 for Large Frame Platforms(.308/7.62)

The CompMag is fixed magazine device for shooters in states with "Assault Weapon" restrictions such as California. This device is a 10-round, fixed, loadable magazine that locks into the firearm. This solution creates an ammunition feeding device that is attached to the firearm that cannot be removed without disassembly of the firearm action.

The Gen 3 CompMag automatically locks into place once inserted into the firearm. Using the CompMag allows you to keep features such as the pistol grip, telescoping stock, forward grip and flash hider.

The CompMag features easy installation, round count indicator, last round bolt hold open, and allows for easy type 3 malfunctions.

Compliance Note: For New York state, the release hole cover must be epoxied over for a permanent installation.

COMPATIBILITY:
DPMS/SR25 compatible.
Compatible ammunition: 7.62X51 / .308 / 6.5 Creedmoor
Compatible with standard AR-10 type lowers.
MCX Spear compatible.
For receivers with Cerakoted magwells we recommend roughing up or 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. Cerakote is a slick, hard surface and will prevent the locking wheel from engaging so it must be removed for the mag to lock in properly.
NOT compatible with lowers that have a custom or extended magazine well. It will work with the Ruger 5610 even though the magwell is not a standard shape.
NOT compatible with H&K MR 7.62 due to the flat magwell shape.
There are reports of mixed reviews when using the CompMag on the LMT MWS 6.5 Creedmoor and the LMT MWS Mars-H. Lately the reviews have been positive. If it does not work, please contact CompMag directly.
NOT compatible in bullpup firearms such as the Tavor as you cannot separate the upper to release the CompMag.
NOT compatible with top loaders such as the MA loader or the Bear Flag Defense loader.
NOT compatible with Armalite AR-10B rifles that accept Armailite magazines.
