CMMG 99D517A Replacement Barrel Kit With Bolt Carrier Group, 9mm Luger 8" Threaded, Black, Radial Delayed Blowback, Fits AR-Platform
CMMG's 9mm Barrel And BCG Kit Allow You To Build a Pistol Caliber Carbine using CMMG's Patent Pending Radial Delayed Blowback System. Unlike Typical Direct Blowback Systems, RDB uses a Bolt That Is Forced To Rotate And unlock, slowing The BCG. This results In a Lighter BCG For a Lighter Rifle, And Less Felt Recoil Than a Straight Blowback System. Their Barrel And Bolt Kits Are Designed To Work exclusively With Mil-Spec AR-15 Upper receivers With a Modified Ejection Port, Like Their MkG/MkGs Upper, And Most Mil-Spec AR15 lowers When Used With 9 AR Conversion Mags as Well as Their MkGs Mk17 And Mk9* lowers. Other manufacturers receivers May Work, But We Cannot Guarantee Function Or Reliability.*Older Mk9 lowers Will Require One Of Their Retrofit kits To Convert It To a Radial Delayed Blowback Compatible Lower, Instead Of Traditional Blowback.
