CMMG DISSENT MK3 | .308 WIN | 16.1in

The CMMG DISSENT Mk3 is a .308 WIN rifle built on CMMG’s Mk3 platform and fitted with a 16.1-inch barrel and a side-folding DISSENT stock. It uses a compact direct-impingement operating system and includes an adjustable gas block, CMMG ZEROED muzzle brake, and two 20-round Magpul PMAG LR/SR magazines. For an optic under $1,000 that pairs well with this configuration, consider a Vortex Viper PST Gen II 1-6×24 for versatile low- to mid-power precision.

Typical real-world applications include precision target shooting and medium-game hunting, where the .308 cartridge and a compact 16.1-inch platform offer a balance of power and maneuverability.
