Product Info for CMMG Dissent, Mk3, 8.6 Blackout, 12.5 inch Upper Receiver
Are you wanting to build a DISSENT Mk3 with the highly anticipated 8.6 caliber? The cartridge is unique for its radical 1:3 twist rate which produces extreme rotational energy. The design allows for shorter barrels and subsonic ammunition to be used.![]()
Pair with a compatible lower receiver and the included 1913 Picatinny rear end plate you can add accessories like slings if you're going for a pistol build or a folding stock if a compact carbine is more your style.
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 ARs. 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.
