The Kriss USA Vector CRB Gen 3 in 45 ACP is a purpose-built pistol-caliber carbine designed for shooters who want a modern, competition-ready firearm without compromise. If you're into PCC matches, tactical sports, or simply want a soft-shooting, 45 ACP carbine that handles like a dream, the Vector CRB delivers the goods. The Gen 3 platform brings a completely reimagined upper and lower receiver that feels more refined and adaptable than its predecessors, with ergonomics tweaked for both right- and left-handed shooters.
At 16 inches, the barrel keeps the Vector CRB legal and handy while the 45 ACP cartridge delivers reliable terminal performance with minimal recoil—a genuine advantage in rapid-fire scenarios or extended range sessions. The closed-bolt, delayed-blowback operating system runs smooth and predictable, and that Arctic Delta Cerakote finish isn't just eye candy; it's durable protection against the elements. The carbine tips the scales at just 7.7 pounds, making it nimble enough to move around a stage or carry on an adventure without fatigue. The ambidextrous telescopic folding stock adapts to your needs, whether you're setting it up for a specific shooting position or collapsing it for transport and storage.
Magazine compatibility is straightforward: the Vector CRB feeds full-size Glock-pattern magazines, so if you already run Glock pistols, you can share ammunition and mags across platforms. The barrel features integrated M-LOK slots for attaching lights, lasers, or foregrips, and the .578x28 right-hand threading opens the door to suppressors and muzzle devices. You get a solid foundation out of the box—one 30-round magazine, cleaning kit, cable lock, and manual—everything you need to get shooting right away.
Whether you're grinding for that next competition win or just want a 45 ACP carbine that's genuinely fun to shoot, the Vector CRB Gen 3 is built for both.
