Upper Group Dissent

Many of you love the 6.5 300BLK DISSENT so we decided to take it and crank it up to 11!... or how about 10.5? 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.

Its 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 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 youre 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. Never too much and never too little.

Lifetime Quality Guarantee

Every CMMG product is backed by a Lifetime Quality Guarantee against material and workmanship defects.

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.
