CMMG has introduced several new AR-15s for 2014. The CMMG Mk4 T-Series of AR carbines is value priced but feature heavy. Chamberings in this versatile line include 9mm, 5.56mm NATO, 300 Blackout or .22 LR, and the rifles have 16-inch barrels in either 416 stainless or 4140 nitrided chrome-moly steel, full-length flattop upper receivers, single-stage triggers and collapsible stocks.
The Mk4 T includes an RKM11 KeyMod free-floating hand guard with a 1913 Picatinny rail on top. The KeyMod slots are found at the 3, 6 and 9 o’clock positions and offer shooters a low-profile mounting alternative to the M1913 Picatinny rail. For accessories that are not yet KeyMod compatible, users can purchase a separate CMMG 5-slot Picatinny adapter rail that can be easily attached to any of the KeyMod slots for optimal placement of the accessories.
