CMMG

CMMG's MkG Guard is an AR15-style pistol chambered in 45 ACP. The Guard is fed from factory Glock 21 magazines and uses CMMG's patent pending Radial Delayed Blowback operating system that tames the 45 ACP cartridge while simultaneously reducing the weight and felt recoil of the rifle. It also features a patent pending dual-pinned, fully machined bolt catch linkage, making operation of the rifle both easy and intuitive. The Guard is threaded (.578"-28 tpi) to accept most common 45 ACP suppressors, and is the perfect carbine for defending your home or enjoying a day at the range. The barrel is 4140 steel with a medium taper, 1:16" twist, and a black SBN (Salt Bath Nitride) finish capped with CMMG's SV muzzle brake. It has a forged 7075-T6 aluminum upper receiver with a billet 7075-T6 aluminum lower receiver, and CMMG's single stage mil-spec style trigger. This model has a black KAK Shockwave Blade stabilizer and tube, Magpul MOE pistol grip, 8" barrel, and CMMG's free-floating 7" keymod handguard.
