AR-15 CompMag Gen.3 - 5.56/.223/.300 BLK

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.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 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.Compatible with other firearms that accept a STANAG (AR-15) magazine and have a removable upper receiver; including the SCAR16, CZ Bren 2 (5.56), Bushmaster ACR, SIG MCX, SIG 556, Galil ACE, BRN180M, Springfield Saint Edge ATC, HK MR556 A4, and Daewoo DR200.NOT compatible with lowers that have a custom or extended magazine well (such as Seekins SP225, Sharps Bros, HK MR556 A1, and Spike's Jack). Not compatible with the AKB-23 receiver.Not compatible with some bullpup firearms such as the Tavor and Steyer AUG as you cannot separate the receiver to remove the CompMag without destroying the magazine.Compatible with the A3 Tactical Triad bullpup chassis. You will need to trim the top of the CompMag loading door to get it fully latch, but it's an easy fix.NOT compatible with top loaders such as the MA loader or the Bear Flag Defense loader.
