Compact and capable, the CMMG Banshee MK4 is designed for optimized performance with short barrels and suppressed or subsonic loads. Chambered in .300 AAC Blackout with a 12.50″ threaded medium-taper barrel, it packages AR functionality into a compact pistol platform. The build includes EML 7″ M-LOK handguards, a tungsten Cerakote aluminum Picatinny rail receiver, and CMMG ZEROED controls for ambidextrous operation. For an optic that pairs well with this platform, consider the Vortex Sparc AR, a small red-dot style sight commonly priced well under $1000 and suited for quick target engagement on AR pistols.
