CMMG Dissent MK4 30AC50F-AB | .300 AAC Blackout | 10.50″

The CMMG Dissent MK4 is a compact AR-style pistol built for portability and modularity. Chambered in .300 AAC Blackout with a 30+1 capacity and a 10.50″ threaded black nitride barrel, it uses CMMG’s Compact Action to house the recoil system in the upper receiver and eliminate the buffer tube. Controls are ambidextrous with a forward non-reciprocating side charger that can be configured for left- or right-handed operation. For a durable, low-profile optic that pairs well with this platform, consider an Aimpoint PRO for its proven reliability and fast target acquisition under $1000.
