The CMMG Dissent MK4 pistol in .338 ARC with a 10.5-inch black nitride threaded barrel (brand part no. 34A840F-AB) combines the AR15 platform’s manual of arms with the reach and stopping power of a large-bore cartridge built to run subsonic or supersonic loads. CMMG pairs the barrel with a 9.6-inch M-LOK handguard, a black Armor Cerakote aluminum Picatinny-rail receiver, and a rear Picatinny rail for optics or accessories. The pistol runs CMMG’s Zeroed 60/90-degree safety and is fitted with a CMMG Zeroed grip, feeding from a 10-round magazine. Among AR pistols, the Dissent MK4 favors shooters who want big-bore versatility in a compact package.
