UPPER GROUP, RESOLUTE, Mk3, .308WIN, 16.1"
Build the ultimate .308 Win carbine with the RESOLUTE® Mk3 upper group. Combining heavy hitting performance with styling in a league of its own, there is no doubt that this upper will set your rifle apart from the crowd. There can be a lot of confusion with .308 AR platforms and compatibility, CMMG has kept it simple by basing our Mk3 platform off the popular Gen 1 DPMS High-Pattern LR308 design, which means greater parts availability and more customization potential. Available in seven different Cerakote finishes, all CMMG® Upper Groups come complete with bolt carrier group and ZEROED™ accessories including:
ZEROED .308 Ambi Charging Handle
