CMMG Banshee MK57 5.7x28mm Features
The Banshee MK57 utilizes the radial delayed blowback operating system, which effectively reduces felt recoil and enhances the firearm’s reliability. The 8″ barrel, constructed from 4140CM steel with a Salt Bath Nitride (SBN) finish, ensures durability and longevity, while the 1:9 barrel twist is ideal for stabilizing the 5.7x28mm rounds. The CMMG ZEROED Linear Compensator attached to the muzzle aids in reducing muzzle rise and enhancing control during rapid fire.
In terms of build quality, the Banshee MK57 boasts a billet 6061 T6 aluminum upper receiver and a forged 7075 T6 aluminum lower receiver, providing a robust yet manageable frame. The CMMG EML7 M-LOK handguard allows for easy attachment of various accessories. A Cerakote finish on the entire firearm enhances its resistance to wear and corrosion. The ambidextrous features, including the CMMG ZEROED charging handle and safety selector, make this firearm adaptable for both right and left-handed users. The integrated trigger guard and CMMG ZEROED pistol grip offer a comfortable and secure grip.
