CMMG Banshee 300 Mk57 AR-style Pistol, 5.7x28mm, 5″ BBL, Graph., 20+1 Rds., Uses FN Five-SeveN Mags

CMMG® BansheeTM 300 Mk57 5.7x28mm Semi-automatic AR-style Pistol

The Banshee is CMMG’s lightest and most compact AR Pistol, delivering 20+1 rounds of 5.7x28mm firepower in a scant 19.2″-long package. Its short overall length and low weight make it ideal for the narrow corridors of home defense and close-quarters applications. The magwell is patterned for FN Five-SeveN mags, so the Banshee is an excellent companion piece to your existing Five-SeveN.

Even better, this handly little Pistol comes loaded with premium features. At the top of the list is the Radial Delayed Blowback operating system, which guarantees less felt recoil while functioning reliably with a wide range of bullet weights.

The Banshee comes equipped with CMMG’s own RipBrace stabilizing brace, which features FastBack technology for rapid deployment: just pull it straight back to deploy it. There are no locking tabs to bind, and an indexing screw lets you pre-set your desired length.

The 300 also features the CMMG Single stage mil-spec and CMMG 4″ handguard with M-LOK slots for accessories. In fact, every component in every CMMG rifle is 100% made in America for quality you can trust.

Pair the Banshee with your existing Five-SeveN pistol, and you’ve got the convenience of magazine interchangeability and the versatility for any scenario.
