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 7.62×39. No matter what the application is, this BANSHEE is built to fit the bill.

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, you’ll always have enough space for those must-have accessories.
