The KRISS Vector’s Super V Recoil Mitigation System is a delayed blowback operating system with a small bolt carrier group connected to a low mass slider guided by channels in the frame that run perpendicular to the barrel. As a result, the KRISS Super V System redirects blowback energy downward, becoming a counterweight to the barrel’s natural tendency to rise when fired.

The KRISS Vector also features thelowest bore axis of any firearm in the world. The barrel is situated below the fire control group, in line with the second knuckle of the dominant hand, giving the operator mechanical advantage over recoil forces. This aids the operator in controlling the KRISS Vector for fast and accurate follow up shots
