CMMG Zeroed Banshee Mk4 Features The CMMG Zeroed Banshee Mk4 runs on a radial delayed blowback operating system with a fixed ejector 6061-T6 aluminum upper a combination tuned specifically for suppressed 9mm shooting. The 6.5 inch chrome moly barrel wears a black nitride finish and a 1:10 twist threaded 1/2x28 to accept the included Zeroed 36 suppressor without any additional parts. That suppressor tucks inside the oversized 11 inch M-LOK handguard which keeps the system compact enough to handle like a standard AR pistol. A forged 7075-T6 lower with a standard AR15 magwell feeds from CMMG s 33 or 10 round 9mm magazines for reliable cycling shot after shot. Every Zeroed Banshee ships with CMMG s premium Zeroed control package: an ambi charging handle single-stage drop-in trigger 60/90 degree ambi safety selector and a Zeroed ambi pistol grip all finished to work together as one system rather than a parts bin assembly. The Midnight Bronze Cerakote receiver carries a Picatinny rail on top for optics mounting while the included CMMG RipBrace rides on a FASTBACK 6-position receiver extension for adjustable fit. Silicone SD-style handguard covers snap into the M-LOK slots for a comfortable grip surface and a 33 round magazine is included in the box. At 6.1 lbs and 27 to 29.5 inches overall the CMMG Zeroed Banshee Mk4 is available for sale at GrabAGun for shooters building a dedicated suppressed 9mm pistol.
