Compact and capable, .300 BLK was designed to be right at home in AR15-pattern firearms like the CMMG Mk4 platform. Originally created for optimum performance in subsonic, suppressed, and short-barrel applications, .300 BLK, in supersonic ammo loadings, has evolved into a popular competitor to other intermediate cartridges like 7.62x39. No matter what the application is, this BANSHEE is built to fit the bill. The BANSHEE series represents the most innovative AR pistols and SBRs available today. From the quick deploying RIPBRACE to the stylized receivers and EML handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. 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, youll always have enough space for those must-have accessories.
