CMMG 8" Barrel and BCG Kit 9mm

CMMG 8" Barrel and BCG Kit 9mmThe CMMG 8" Barrel and BCG Kit in 9mm is a high-quality kit that allows you to build a Pistol Caliber Carbine using CMMG's Patent Pending Radial Delayed Blowback System. This system reduces felt recoil and produces a lighter BCG for a more lightweight rifle than straight blowback systems. The kit is designed to work with mil-spec AR-15 upper receivers with a modified ejection port, and most mil-spec AR-15 lowers when used with 9 AR Conversion mags or CMMG MkGs Mk17 and Mk9* lowers. The kit features precise manufacturing, long-term reliability, and durable construction for a top-performing Pistol Caliber Carbine.*Older Mk9 lowers will require a CMMG retrofit kit to convert it to a Radial Delayed Blowback compatible lower, instead of Traditional Blowback.Features Precise Manufacturing Long Term Reliability Durable ConstructionAll NFA/ATF Rules ApplyYou may use this AR-15 barrel with a lower receiver that is a Registered SBR, Machine Gun, or Pistol. Possession of this barrel, along with a non-NFA lower receiver, is prohibited, except when installed on a Pistol configuration firearm. Check your local laws and jurisdictions.
