Description

Product Overview

The CMMG Banshee Mk4 is an AR-style pistol chambered in 5.7x28mm FN and built around CMMG’s radial delayed blowback operating system. Its eight-inch salt bath nitride-treated 4140 chrome-moly steel barrel uses a 1:9 twist and is paired with a ZEROED linear compensator threaded 1/2x28. The billet aluminum upper, forged Mk4 lower, EML7 M-LOK handguard, ambidextrous charging handle, and ZEROED drop-in trigger create a compact, adaptable platform. A continuous top rail supports the addition of an optic, while the ambidextrous 60/90-degree safety selector and ZEROED pistol grip provide ergonomic controls. The package includes one 32-round magazine.
