The Kriss USA Vector CRB G3 in 45 ACP is a modern, compact carbine built for shooters who want rifle-like controls and ergonomics in a pistol-caliber platform. This 16-inch barrel semi-automatic carbine uses a closed-bolt delayed blowback operating system to deliver reliable, soft-shooting performance with straightforward maintenance and minimal moving parts. The Vector CRB is at home on the range, in tactical training courses, or as a truck gun for hunters and sport shooters who appreciate its lightweight, maneuverable design and natural pointability.
Finished in Flat Dark Earth, the Vector CRB G3 wears a durable black nitride barrel and features KRISS's signature ambidextrous telescopic folding stock, which collapses to 34.9 inches for transport or storage and extends to 36.9 inches for shooting. At 7.7 pounds, it's nimble enough for one-handed movement in tight spaces yet substantial enough to manage recoil with authority. The barrel is threaded .578x28 (RH) for suppressors, allowing you to run this natural host gun quietly if you choose. The included 30-round magazine keeps you supplied through extended range sessions or training drills, and the single-stage pivoting trigger breaks clean for consistent shooting.
Built on the KRISS operating system that's earned a reputation for reliability and ease of use, the Vector CRB G3 consolidates 45 ACP's proven terminal performance into a platform that handles like an AR but feeds on common pistol ammunition. Whether you're a competitive shooter, a serious hobbyist, or someone building a versatile home defense battery, the Vector CRB delivers the handling and ergonomics of a rifle without the complexity or the price tag of larger caliber alternatives.
