Upper Group, DISSENT, .45 ACP, 16.1"
Adding some variety to your arsenal. Equipped with our Radial Delayed Blowback Compact Action there’s no other .45 ACP PCC upper that compares. Kick off a new build or ditch the buffer system on an existing MkG lower.
.45 ACP DISSENT uppers are only designed for use with CMMG MkG lowers, other manufacturers’ lowers may work but CMMG cannot guarantee function.
