CMMG 22D7C6C Replacement Barrel Kit with Bolt Carrier Group, 22 LR 16.10″ Threaded, Black Nitride Chromoly Steel, Fits AR-15/Mk4

Description

The CMMG 22D7C6C provides you with all the necessary elements to convert your current upper into a dedicated .22LR. All that’s missing is a magazine, and then you’ll be completely set. To obtain optimal performance, it is recommended to use a round style hammer as the notched hammers may lead to functional issues. Furthermore, our testing has shown that 36 grain plated nose bullets are the top choice for this conversion due to their consistent performance.
