CMMG DISSENT MK4 Pistol .300 AAC Blackout 10.5″ 30+1

The CMMG DISSENT MK4 is a compact semi‑automatic pistol chambered in .300 AAC Blackout designed for users who need a short-barrel, versatile platform. Its 10.50″ threaded barrel and adjustable gas block allow reliable function across supersonic and subsonic loadings.
