The CMMG Dissent Mk3 8.6 Blackout AR Pistol provides a capable platform for modern sporting and defensive applications. The 8.6 Blackout cartridge is engineered for enhanced terminal performance and consistent cycling, particularly from shorter barrel configurations.
Key Features
Caliber Optimization
The 8.6 Blackout cartridge is paired with a rapid 1:3 barrel twist rate. This specification ensures precise stabilization of heavier .338 caliber projectiles, contributing to consistent ballistic performance and efficient sound signature reduction when integrated with a suppressor. This design mirrors the operational characteristics observed in optimized .300 Blackout platforms.
Construction and Durability
The Dissent Mk3 utilizes a black nitride finished 7075-T6 aluminum receiver, providing structural integrity and advanced corrosion resistance under demanding operational conditions. Its 12.5-inch barrel, also treated with black nitride, ensures durability and wear resistance critical for sustained use.
Ergonomics and Adaptability
An 11-inch proprietary handguard offers extensive attachment points for various firearm accessories, facilitating customization. The integrated CMMG Zeroed Grip enhances weapon control and handling. The pistol features a rear 1913 Picatinny rail, permitting the secure attachment of braces or slings, thereby allowing adaptation to diverse user preferences and mission requirements.
