The CMMG Banshee FR MkG in the caliber that won two World Wars and inspired the creation of the Radial Delayed Blowback system. Like all of our .45 ACP pistols and rifles, this BANSHEE is built on the MkG platform and is designed to use Glock-pattern .45 ACP magazines. Featuring quick deploying RIPBRACE; EML handguards with full length M-LOK slots on both sides and the bottom of the handguard as well as M-LOK between the top Picatinny rail sections, you'll always have enough space for those must have accessories. Includes 13rd Glock magazine.
