CMMG Dissent 16.10" Upper .22 ARC with 1:7 Twist Rate and M-LOK Rail - Rifle-Length with Charging Handle - Armor Black - 28B940CAB

Upgrade your DISSENT MK4 with our .22 ARC (Advanced Rifle Cartridge) upper group, whether you're starting from scratch or expanding your caliber options. Pair it effortlessly with any Mil-Spec compatible lower receiver and utilize the included 1913 picatinny rear end plate to customize with accessories like slings for a pistol build or a folding stock for a compact carbine setup. Our patent-pending direct impingement Compact Action design ensures that DISSENT upper groups house the entire action and recoil assembly within the upper receiver, resulting in reduced bulk and length compared to traditional AR pistols. The forward non-reciprocating side charger facilitates quick bolt operation without losing target acquisition and left side chargers are standard on direct impingement DISSENT models, with right side options available here. Every DISSENT upper group includes a 1913 picatinny rail end plate for versatile configuration without the need for a lower receiver buffer tube. Fine-tune your DISSENT for suppressed shooting or optimize it for your preferred ammunition with the adjustable gas block, providing precise control over the gas system for optimal performance every time.
