The CMMG Dissent Mk3 Rifle (CMMG part no. 38A730CAB) is built around the .308 Winchester cartridge on CMMG’s larger-frame Mk3 platform, finished in Armor Black. The 16.1-inch barrel is machined from 4140 chromoly with a nitride finish for durability and corrosion resistance without sacrificing performance, running a direct-impingement operating system through a rifle-length, adjustable 0.750 gas block. A 7075-T6 aluminum upper and billet lower receiver anchor the build, while a side-folding DISSENT stock and a reversible Dissent side charging handle make this one of the more compact, travel-friendly .308 platforms available. A CMMG ZEROED single-stage trigger, ZEROED pistol grip, and a 60/90-degree ZEROED safety selector round out a rifle that ships with two 20-round Magpul PMAGs.
