Let's face it, the 6.5" Dissent 5.56 is a ton of fun, and it's rowdy! Now that we got that out of Cmmg's system, our ears quit ringing, and Cmmg aren't seeing fireballs anymore, Cmmg are able to bring the same patent pending compact action to even more people with the arrival of the Cmmg Dissent Mk4 5.56mm 10.5" Upper Group (55B8D86). A longer barrel will give improved ballistics, while the Dissent's compact platform still keeps this as a small, but powerful pistol to fill your needs.

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 Cmmg's 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.

Adjustable Gas Block. If you're looking to shoot suppressed or just fine tune your Dissent to your preferred ammo, the adjustable gas block gives you the freedom to dial in the gas system exactly to your liking.
