Overview

The CMMG Dissent Mk4 is a compact, semi-auto rifle chambered in .338 ARC. It features a patent-pending Compact Action, which houses the entire recoil system within the upper receiver, eliminating the need for a traditional buffer tube. This design facilitates a 10.5-inch threaded barrel and a 9.60-inch M-LOK free-float handguard, making it highly maneuverable for tactical operations. The rifle is built with aircraft-grade aluminum receivers finished in Black Armor Cerakote and includes a non-reciprocating side charger. Additional features include an accessory-ready rear Picatinny rail, CMMG Zeroed grip, and a linear compensator. The platform uses 1:8" twist rifling and is designed to provide rifle-class ballistics in a compact footprint. It ships with a 10-round magazine.
