Upper Group Dissent 45 ACP 6.5 inch upper designed to house the entire action and recoil assembly in the upper receiver for bufferless operation. Built around the Dissent Compact Action and Radial Delayed Blowback technology with fixed ejector, it is intended for pistol configurations. Features a forward non-reciprocating side charger for bolt operation without leaving the target. Includes a 1913 Picatinny rail end plate to use in place of the lower receiver buffer tube. Lifetime Quality Guarantee. 6.5 inch upper groups are designed for use with CMMG MkG lowers; other lowers may work but CMMG cannot guarantee function. NFA rules may apply when used with a stock or brace on a pistol lower.
