Overview
The CMMG BANSHEE MK4 represents a purpose-built AR pistol engineered for maneuverability and rapid deployment in diverse operational environments. Designed on the robust AR-15 MK4 platform, this system integrates durable construction with critical performance features, making it a reliable asset for serious users requiring a compact yet potent firearm.
Key Features
Compact Form Factor
The BANSHEE MK4’s defining characteristic is its compact profile, facilitated by a 10.5-inch barrel. This length optimizes the platform for close-quarters engagements, vehicle operations, and confined space applications, providing a reduced overall length without severely compromising ballistic performance of the 5.56mm NATO cartridge. The integrated pistol brace enhances stability and control during firing, allowing for consistent shot placement under dynamic conditions.
Robust Construction
Constructed with a forged 7075-T6 aluminum upper and lower receiver, the BANSHEE MK4 delivers the durability and impact resistance expected from a professional-grade AR-pattern firearm. The 10.5-inch barrel is precision machined from 4140 or 4150 CrMoV steel, ensuring long-term accuracy and service life even under sustained firing schedules. All components are subjected to stringent quality control to ensure operational reliability and consistency.
Gas System and Muzzle Management
Utilizing a direct impingement gas system, the BANSHEE MK4 provides a reliable cycle of operation, critical for consistent function in varied conditions. The integral muzzle brake mitigates recoil and muzzle rise, facilitating faster follow-up shots and maintaining target acquisition efficiency. This combination ensures consistent performance and enhanced user control.
Versatile Caliber
Chambered in 5.56mm NATO, the BANSHEE MK4 offers compatibility with both 5.56x45mm NATO and .223 Remington ammunition, providing operational flexibility and widely available ammunition options.
