CMMG DISSENT MK4 300BLK 10.5″ | 30AC278AB

The CMMG DISSENT MK4 is a compact .300 AAC Blackout pistol built around a 10.5″ threaded barrel and a host of features intended for short-barrel AR-style use. It removes the conventional buffer system for a more compact, portable platform and is fitted with a Picatinny end plate for a folding brace or stock solution. This configuration includes an adjustable gas block and a TriggerTech AR-D trigger calibrated to CMMG’s upper groups for a consistent, light break.

For optics, a durable red-dot such as the Vortex SPARC AR (well under $1,000) pairs appropriately with the DISSENT for close-quarters and suppressed work while keeping the profile compact. Typical applications include suppressed range use and short-range practical or training scenarios where a compact AR-style pistol is preferred.
