Many of you love the 6.5" 300BLK Dissent, so Cmmg decided to take it and crank it up to 11! ... or how about 10.5? Cmmg Dissent Mk4 300BLK 10.5" Upper Group (30BC239) - Giving you improved ballistics and an even more suppressor friendly length, this all new length 300BLK upper is just the ticket to finish your 300BLK AR pistol build.

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 Cmmg's answer. Utilizing our patent pending direct impingement Compact Action, Dissent Upper Groups house 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.

*NFA Rules May Apply. 6.5" Dissent Upper Groups are made to be used in a pistol configuration, using a pistol upper in conjunction with a stock or stabilizing brace on the lower receiver may make your Dissent and SBR and subject to NFA rules.
