CMMG BANSHEE 300 MKG 5.7X28 AR PISTOL
CMMG Banshee 300 MK57 Five Seven AR Pistol
Shaped like a rifle cartridge with a bottleneck yet short like a pistol round, the 5.7×28 boasts high velocity out of the 5” barrel and very little recoil making this a blast to shoot. The barrel is made from 4140 steel and salt bath Nitride finished for extreme durability. This is a radial delayed blowback rifle, so there is no need for a gas block or gas tube making for an extremely simple and reliable system. The 4” RML handguard features M-LOK slots for attaching accessories and features a top Picatinny rail that sits flush with the flat top upper receiver. The CMMG Mk57 Banshee 300 AR-15 pistol is a compact package that shoots a unique and cutting-edge cartridge.
