CMMG Banshee Mk4 Pistol, .300 Blackout, 12.5-Inch, Coyote Tan

The CMMG Banshee Mk4 pistol in .300 AAC Blackout with a Coyote Tan Cerakote finish (brand part no. 30AB20FCT) was designed to be right at home in AR15-pattern platforms, running the full range of subsonic and supersonic .300 Blackout loads. CMMG cuts the 12.5-inch barrel to a medium-taper profile with a Black Nitride finish and threads the muzzle for a compensator or suppressor, and the EML 7-inch M-LOK handguard carries full-length slots on both sides and the bottom, plus M-LOK sections between the top Picatinny rail. The pistol comes equipped with a full set of CMMG ZEROED parts, including a drop-in trigger and a 60/90-degree ambidextrous safety selector. Among AR pistols tuned for .300 Blackout’s versatility, this Banshee Mk4 configuration favors shooters who run both subsonic and supersonic loads through the same platform.
