The CMMG Banshee Mk4 .300 Blackout AR Pistol is engineered for compact performance, integrating the .300 BLK cartridge into a highly effective AR15-pattern firearm. This platform is specifically configured to optimize performance in suppressed, subsonic, and short-barrel applications, making it a robust solution for diverse operational requirements.
Key Features
Optimized .300 Blackout Performance
The Mk4 platform is purpose-built for the .300 Blackout cartridge, ensuring optimal ballistic performance across its design parameters. This configuration prioritizes versatility in suppressed operations and maintains terminal effectiveness within a compact footprint.
Robust Receiver Construction
Constructed from durable aluminum, the receiver features a Coyote Tan Cerakote finish, providing enhanced corrosion resistance and a non-reflective surface. An integrated Picatinny rail allows for direct optics and accessory mounting, ensuring precise alignment.
Integrated Handguard System
The EML M-LOK handguard provides full-length M-LOK attachment slots along the sides and bottom. Additional M-LOK sections are present between the top Picatinny rail segments, offering extensive modularity for lights, lasers, and other mission-critical accessories without excessive bulk.
Ergonomic Control Interface
Equipped with a CMMG RipBrace, this pistol facilitates rapid deployment and provides a stable shooting platform. The CMMG Zeroed Grip enhances weapon manipulation and user comfort, contributing to improved control and reduced fatigue during extended engagements.
Barrel Precision and Durability
An 8-inch barrel, finished with Black Nitride for superior wear and corrosion resistance, is threaded for direct attachment of muzzle devices or suppressors. This barrel length is specifically chosen to leverage the .300 Blackout’s ballistic properties in compact configurations.
Standardized Magazine Integration
The system includes a 30-round Magpul PMAG, ensuring reliable feeding and broad compatibility with existing AR15-pattern magazines.
