Description
Product Overview
The CMMG MkG45 Guard is an AR-style pistol chambered in .45 ACP and built around CMMG’s radial delayed blowback operating system. This design helps manage recoil while maintaining a compact, lightweight platform. The pistol uses Glock 21 magazines and features an 8-inch 4140 steel barrel with a 1:16-inch twist, Salt Bath Nitride finish, and .578-28 threaded muzzle capped by a CMMG SV muzzle brake. A forged 7075-T6 aluminum upper receiver pairs with a billet 7075-T6 aluminum lower receiver, while the 7-inch free-floating KeyMod handguard provides mounting space for accessories. The package includes a KAK Shockwave Blade stabilizer, Magpul MOE pistol grip, and single-stage mil-spec style trigger. It is optic ready and supplied without conventional sights.

Best firearm I've...
Best firearm I've bought in the last few years! Bought (2) of these from Bud's. Took one out today to the range to try it out. Not disappointed! Firearm is light, easy to transition from one target to another. Performed flawlessly. Put a Sig red dot on top and never missed a shot. Rang all the metal targets every time. If you want a home defense firearm w/o having to worry about the over penetration / legal liability of a 5.56 this is the one to choose.

Amazing pistol caliber...
Amazing pistol caliber carbine pistol. I've put over 500 rounds through my with a suppressor and have had zero malfunctions. Fit and finish are impressive. This trigger is the smoothest trigger I've ever felt out of a stock AR-15. The trigger is smoother than my Colt LE6920. Glad I bought some 26rd mags, because it is a lot of fun to shoot. My EOTech from my 300 blackout has the same POI when placed on this. Would buy again.
