CMMG Mk4 HT 22LR Upper Group BLACK
We have 5 of these coming on our next shipment and can be Pre-ordered.
The Mk4 HT Upper Group features CMMG’s RKM11 KeyMod free float hand guard. Either a 416 stainless or nitrided 4140 CrMo steel barrels in a heavy taper profile are offered in 5.56mm and 300 BLK. The 22LR model is only available in the nitrided 4140 CrMo type barrel. For best performance use a round style hammer as notched hammers can cause function issues and 36 grain plated nose bullets have proven to be the best choice for function.
