CMMG makes a number of complete AR-15 patterned rifles as well as Pistol Caliber Carbines, not to mention Conversions. Today I take a look at the CMMG Mk57 8″ Conversion. A complete upper receiver, bolt carrier group and magazine that converts any Mil-Spec lower receiver into a 5.7x28mm firearm.
I’ve used this Mk57 conversion quite a bit, to include using it in a Runenation Level 2 Carbine Course. It is great in that it offers you all of the familiarity of a AR-15 with significantly less recoil and suppresses much nicer when compared to a 5.56. Not to mention it is a ton of fun to shoot…
You can find the CMMG 5.7 Conversion here.
