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.
It’s no secret that pistol stabilizing braces have been a target for scrutiny over the years, and those that enjoy building their own AR pistols have wondered what will come out of all the uncertainty. DISSENT is our answer. Utilizing our patent pending Compact Action and Radial Delayed Blowback technology with fixed ejector, .45 ACP DISSENT upper group houses the entire action and recoil assembly in the upper receiver, resulting in less bulk and length than traditional AR pistols. The forward non-reciprocating side charger allows for quick bolt operation without coming off target.
DISSENT Upper groups include a 1913 Picatinny rail end plate to use in place of the lower receiver buffer tube.
