CMMG Banshee MK4 Pistol | .300 AAC Blackout | 12.5 in | 30AB20FAB

The CMMG Banshee Mk4 in .300 AAC Blackout is a compact AR-pattern pistol configured for short-barrel and suppressed applications. It features a 12.5-inch threaded 4140CM barrel fitted with a CMMG ZEROED linear compensator and ships with a RipBrace pistol brace and a 30-round Magpul PMAG. Controls and components use CMMG ZEROED parts, including an ambidextrous charging handle, 60/90-degree ambi safety, and a drop-in trigger.
