The KRISS Vector CRB Gen 2 is a 16″ barrel semi-auto version of the KRISS Vector SMG. The KRISS Vector CRB shares the same milspec frame, Super V operating system, materials and rugged housing as the KRISS Vector SMG. Same light weight. Same maneuverability. Same simple and easy to maintain Super V mechanism that reduces felt recoil by more than 60% and reduces barrel elevation by more than 95%. If your goal is put more rounds on-target, more of the time, then the CRB will exceed your every expectation and demand.
