CMMG DISSENT MK4 300BLK 10.5 in
About this product
The CMMG DISSENT MK4 is a compact AR-style pistol built around a bufferless DISSENT system and a 10.5 inch barrel to deliver a shortened, highly portable platform chambered for .300 AAC Blackout. Its design eliminates the traditional AR-15 buffer tube, making it suitable for users seeking a compact option for short-range or suppressed shooting applications. The adjustable gas block allows tuning for supersonic or subsonic loads while the 1913 Picatinny rail end plate accepts a folding pistol brace or stock to suit different carry and storage preferences. The TriggerTech AR-D trigger, developed with CMMG for this platform, offers a light, repeatable break with a listed pull weight of 4 lb.
