The KRISS Vector SBR (brand part no. KV45-SAP30) brings KRISS TDI’s Super V delayed-blowback system to a .45 ACP short-barrel rifle, giving suppressor hosts and NFA collectors a low-recoil pistol-caliber platform in a 6.5-inch-barrel package. The folding stock and low bore axis keep the big-bore .45 ACP flat-shooting for close-range work, home defense, and range use. Because the barrel is under 16 inches on a stocked rifle, this configuration is a regulated short-barrel rifle.
