CMMG Banshee MK4 Features
The CMMG Banshee MK4 operates on a direct impingement system, providing smooth and reliable cycling. The 10.5″ barrel, featuring a 1:7 twist rate, is constructed from 4140CM steel with a Salt Bath Nitride (SBN) finish, offering enhanced durability and resistance to wear and corrosion. The barrel is equipped with a CMMG ZEROED Linear Comp and threaded with a 1/2×28 pattern, providing effective recoil reduction and compatibility with various muzzle devices.
This firearm’s upper receiver is machined from billet 6061 T6 aluminum, while the lower receiver is forged from 7075 T6 aluminum, both finished in Cerakote for superior protection against the elements. The CMMG EML9 M-LOK Hand Guard offers ample space for mounting accessories, and the CMMG ZEROED Ambi Charging Handle ensures smooth and reliable operation. The CMMG ZEROED Pistol Grip and ZEROED Trigger Guard enhance the ergonomic design, offering comfort and control during extended shooting sessions.
The CMMG RipBrace with CMMG 6 Position Fastback Extension allows for quick and easy adjustments, providing flexibility for different shooting scenarios. The ZEROED Drop-In Single Stage Trigger delivers a crisp and consistent trigger pull, while the ZEROED 60/90 Degree Safety Selector offers ambidextrous operation, catering to both right- and left-handed users. This model comes with a 30-round Magpul PMAG, ensuring you are well-prepared for any situation.
