Product Info for CMMG Dissent Mk4 .350 Legend 16.1in Upper Group

Don't leave your DISSENT at home during deer season, this 350 Legend upper group is just what you need to compliment an existing DISSENT lower or a new AR15 lower build.image

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. Direct impingement DISSENTS come equipped with a left side charger standard. Right side charging handles for DI models are available here.

All DISSENT Upper groups include a 1913 Picatinny rail end plate to use in place of the lower receiver buffer tube.
