The CMMG Banshee Mk4 chambered in 5.7x28mm is designed to deliver carbine-level ballistic performance within a highly maneuverable, compact AR pistol platform. Built on the established Mk4 system, this configuration integrates a robust component set to optimize both utility and operational reliability.
Key Features
Caliber & Performance
Chambered in 5.7x28mm, this Banshee Mk4 variant provides a flat-shooting trajectory and terminal performance suitable for a compact system, effectively balancing the advantages of a pistol with an extended ballistic envelope. The 32+1 round capacity supports sustained engagement capabilities.
Receiver & Handguard System
The Mk4 platform receiver is constructed from aluminum with a Black Armor Cerakote finish, providing resistance to abrasion and corrosion. It features an integrated Picatinny rail for direct optics mounting. The CMMG EML 11″ M-LOK handguard offers extensive accessory attachment points, with full-length M-LOK slots on the sides and bottom, and additional M-LOK segments positioned between the integrated top Picatinny rail sections.
Barrel Configuration
The medium taper barrel is finished with Black Nitride, enhancing its wear resistance and inherent lubricity. Its threaded muzzle is ready for direct attachment of appropriate muzzle devices or suppressors.
CMMG ZEROED Components
This Banshee Mk4 is equipped with a comprehensive suite of CMMG ZEROED components, engineered for enhanced ergonomics and control. These include a ZEROED pistol grip for positive weapon retention, a precise drop-in trigger for consistent pull characteristics, a 60/90 degree ambidextrous safety selector for adaptable manipulation, and an ambidextrous AR15 charging handle for expedient operation from either side. A ZEROED linear compensator is installed to redirect blast forward, mitigating felt recoil and muzzle rise. Further ZEROED enhancements include an ambidextrous magazine catch, an extended magazine release button, a robust bolt catch, and a polymer dust cover for receiver protection.
