CMMG Dissent MK4 300 Blackout 6.5" Pistol 30rd Midnight Bronze

The CMMG Dissent MK4 transforms 300 Blackout performance in a compact platform that delivers rifle-caliber power without traditional rifle constraints. This pistol configuration maximizes subsonic ammunition effectiveness while maintaining portability for close-quarters applications.

What Makes This Different

Built on CMMG's proven MK4 platform, the Dissent incorporates a unique operating system that cycles both supersonic and subsonic 300 Blackout loads reliably. The 6.5-inch barrel length optimizes powder burn for this cartridge while the Midnight Bronze Cerakote finish provides superior corrosion resistance compared to standard phosphate coatings. The integrated Picatinny buffer adapter allows for brace or stock attachment without additional components.

Key Features

• Zeroed Drop-In single-stage trigger with crisp 4.5-6 lb pull weight
• 6.5-inch barrel optimized for 300 Blackout ballistics and suppressor compatibility
• Midnight Bronze Cerakote finish rated for 2,400+ hours salt spray resistance
• 30-round magazine capacity with STANAG compatibility
• Picatinny buffer adapter for direct brace/stock mounting
• Standard AR-15 controls and manual of arms

Field performance demonstrates consistent cycling with bullet weights from 110 to 220 grains, making this platform suitable for both hunting applications and tactical use. The barrel's 1:7 twist rate stabilizes heavy subsonic projectiles effectively, while the gas system handles rapid-fire strings without reliability issues. Weather sealing at critical junctions maintains function in adverse conditions.
