CMMG Banshee MK4 9mm Features

The Banshee MK4 utilizes the radial delayed blowback operating system, renowned for its ability to reduce felt recoil and improve overall handling. The 5″ barrel, crafted from 4140CM steel with a Salt Bath Nitride (SBN) finish, ensures durability and consistent performance. A 1:10 barrel twist rate is ideal for stabilizing a wide range of 9mm bullet weights, contributing to the firearm’s versatility. Equipped with the CMMG ZEROED Linear Compensator, the Banshee MK4 effectively mitigates muzzle rise, allowing for better control and accuracy.

The firearm’s construction features a billet 6061 T6 aluminum upper receiver and a forged 7075 T6 aluminum lower receiver, offering a robust yet lightweight frame. The CMMG EML4 M-LOK handguard provides flexibility for accessory attachments. A standard Cerakote finish enhances the Banshee MK4’s resistance to wear and corrosion. The CMMG ZEROED ambidextrous charging handle and safety selector cater to both right and left-handed shooters, while the CMMG RIPBRACE ensures stability and comfort during shooting.
