Upper Group, DISSENT, .45 ACP, 6.5"
Launching some big lead doesn’t have to come from a bulky platform. Whether you’re building a new .45 ACP PDW or are looking to breathe some new life into a classic MkG, this 6.5” upper group comes with the essentials needed for bufferless range time.
.45 ACP DISSENT uppers are only designed for use with CMMG MkG lowers, other manufacturers’ lowers may work but CMMG cannot guarantee function.
