CMMG Banshee MK4 | .300 BLK | 8″ Barrel | 30rd

The CMMG Banshee Mk4 is an AR-pattern pistol chambered in .300 AAC Blackout with an 8″ threaded barrel, purpose-built for short-barrel and suppressed use while retaining standard AR ergonomics. It ships with CMMG ZEROED components, a 7″ EML M-LOK handguard and a Rip Brace pistol brace for compact handling. For optics, a compact low-power variable such as the Vortex Strike Eagle 1-6×24 pairs well with this platform for fast target acquisition and close-range precision without exceeding typical $1,000 budgets.
