The Kriss Vector Gen II CRB .45 ACP semi-auto rifle is a modern, compact platform built on the company's legendary delayed-blowback operating system. Chambered in .45 ACP—the classic cartridge favored for target shooting, home defense, and specialized applications—the Vector Gen II delivers reliable, straight-shooting performance in a chassis that adapts to how you shoot. Its collapsible design and intelligent ergonomics make it equally at home on the range, in a defensive role, or as a dedicated .45 ACP rifle for shooters seeking something genuinely different from the AR platform.
The heart of the Vector is Kriss's patented KSV System, a closed-bolt delayed-blowback design engineered to manage recoil impulse and enhance controllability. Combined with the rifle's 16-inch barrel and relatively lightweight profile at 7.8 pounds, the Gen II CRB delivers a handling experience that rewards precision shooting. The adjustable stock collapses from 38.5 inches to 35.25 inches, giving you flexibility for different shooting positions, vehicle stowage, or storage space. Overall height stays compact at 6.8 inches, keeping the optics rail and controls in an intuitive, natural position.
Built on an advanced metal and polymer frame, the Vector Gen II is designed for hard use. The 30-round magazine capacity means extended shooting sessions without frequent reloads—practical for tactical practice, competition, or high-volume range days. If you're looking for a .45 ACP rifle that stands apart from conventional designs, the Vector Gen II CRB brings proven reliability and distinctive ergonomics to the table.
