Product Overview
The CMMG Banshee MK4 AR Pistol chambered in .300 Blackout delivers a compact, high-performance solution for the AR-15 platform. Engineered to leverage the capabilities of the .300 BLK cartridge, this firearm is configured for reliable operation and enhanced maneuverability across various applications. Its design integrates proven CMMG ZEROED components to ensure consistent function and user-centric ergonomics.
Key Features
Caliber and Platform Integration
The .300 Blackout cartridge is purpose-built for AR-15 pattern firearms, offering versatility for suppressed and unsuppressed applications. The Banshee MK4 platform is optimized to cycle this cartridge reliably, providing consistent performance whether deploying subsonic or supersonic loads.
Barrel Configuration
This Banshee MK4 features a 12.50-inch medium taper barrel with a black nitride finish. The barrel is threaded, allowing for the direct attachment of suppressors or alternative muzzle devices. A CMMG ZEROED Linear Compensator (optimized for .308 Win) is factory installed to mitigate muzzle blast directed toward the shooter, enhancing operational comfort.
Handguard System
The EML 7-inch M-LOK handguards provide extensive accessory mounting capability. Full-length M-LOK slots are integrated on both sides and the bottom, with additional M-LOK attachment points positioned between the top Picatinny rail sections. This design maximizes modularity while maintaining a streamlined profile.
Integrated ZEROED Components
KFF Defense notes the inclusion of a comprehensive suite of CMMG ZEROED components designed to optimize the user interface. These include a ZEROED pistol grip for enhanced ergonomics, a ZEROED drop-in trigger for a consistent pull, and a 60/90-degree ambidextrous safety selector for rapid and secure manipulation. An ambidextrous Mk47 charging handle facilitates efficient operation from either side, complemented by an AR-15 polymer dust cover.
Receiver and Finish
The receiver assembly is constructed from aluminum with a durable Coyote Tan Cerakote finish, providing robust corrosion resistance and a low-glare matte appearance. A full-length Picatinny rail on the upper receiver allows for precise optics and sight integration.
Magazine Inclusion
The system ships with a 30-round Magpul magazine, providing immediate operational readiness.
