The CMMG Dissent MK4 .338 ARC is a high-performance direct impingement tactical pistol engineered for precision, maneuverability, and durability. It features a 10.5-inch threaded barrel, 9.6-inch M-LOK handguard, and a side-folding polymer stock designed for compact handling and superior performance. The Black Armor Cerakote finish provides exceptional durability, while the CMMG Zeroed Linear Compensator enhances muzzle control for reduced recoil.
The 10.5″ barrel with a 1:8 twist rate accommodates traditional .338 projectiles, making it ideal for reloaders, and it shares bolt compatibility with 6.5 Grendel AR-15s for enhanced versatility. This pistol delivers exceptional energy on target, mirroring the 300 Blackout’s subsonic and supersonic adaptability while requiring minimal gas system adjustments for suppressed or unsuppressed use. The adjustable gas block supports reliable cycling across different configurations.
A monolithic Picatinny rail enables easy optic and accessory mounting, while the M-LOK handguard provides ample space for additional attachments. The CMMG Zeroed 60/90-degree safety selector provides a user-friendly interface. The direct impingement operating system ensures reliability, and the side-folding stock enhances compactness for transport and storage. Weighing 4.9 lbs and measuring 18.7″ in length, the Dissent MK4 ships with one 10-round capacity CMMG .338 ARC magazine.
