About CMMG Barrel and BCG Kit 4140CM SBN Drop in Barrel 5.7 x 28mm 5" Barrel Black
The CMMG Barrel and BCG Kit 4140CM SBN Drop in Barrel 5.7 x 28mm 5" Barrel Black is engineered for durability and reliable performance in AR builds chambered in 5.7x28mm. It features CMMG's patented Radial Delayed Blowback operating system, which reduces bolt carrier group weight and recoil compared to traditional direct blowback systems.
This kit is compatible with mil-spec AR15 uppers and can be used with either a CMMG Mk57 lower receiver or a standard Mk4/AR-15 lower receiver when paired with CMMG 5.7 AR Conversion Magazines. The barrel length is 5 inches and finished in black for corrosion resistance.
