UPPER GROUP, DISSENT, 9MM, 10.5"
What can we say? Some of you just want to be like Dirty Harry. You want your favorite handgun caliber, but you want that nice longer barrel. Well wait no longer! The all-new DISSENT 9mm Upper is available in with a 10.5” barrel! So go ahead… make your day… by completing your 9mm DISSENT build in a way that Dirty Harry would be proud.
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, 9mm 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.
