CMMG BNSHE MK4 300BLK 8″ PB 30RD MB

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.
