UPPER GROUP, DISSENT, Mk4, 6MM ARC, 16.1"

Building a medium-long range DMR doesn't have to mean totting a large unwieldy rifle around. Combing the flat shooting characteristics of 6mm ARC with the revolutionary DISSENT Compact Action, this upper group gives you the ability to build with a new AR15 lower or upgrade your existing DISSENT lower to an instrument with long-range proficiency.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.All DISSENT Upper groups include a 1913 Picatinny rail end plate to use in place of the lower receiver buffer tube. Upper groups are available in your choice from seven Cerakote finish options.Adjustable Gas BlockIf 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. Never too much and never too little.Lifetime Quality GuaranteeWe aim to please, that's why every CMMG product is backed by our Lifetime Quality Guarantee against material and workmanship defects.
