Kriss Usa Vector Crb G3 45Acp 5.5 Arctic 10Rd

The Kriss USA Vector CRB Gen 3 in 45 ACP is a modern, semi-automatic rifle built for shooters who want serious stopping power in a genuinely compact platform. This Arctic-finished 45 ACP carbine bridges the gap between a traditional pistol-caliber rifle and a tacticool modern sporting rifle, delivering the controlability of a long gun with the familiarity and logistics of pistol ammunition. The Vector Gen 3's redesigned upper and lower housings enhance ergonomics and hand support, making it at home on the range, in a home-defense role, or anywhere you need a reliable 45 ACP platform that doesn't hog space or weight.

At 5.6 pounds and just 15.35 inches when collapsed, the Vector CRB punches above its compact footprint. The 5.5-inch barrel is topped with a .578×28 RH threaded muzzle—perfect for suppressor enthusiasts. Inside, a closed-bolt delayed-blowback operating system keeps recoil manageable and cycles reliably across the board. The pivoting single-stage trigger breaks cleanly and predictably, and the Arctic Delta Cerakote finish not only looks sharp but resists corrosion and wear.

Magazine compatibility with full-size Glock magazines means you'll find ammo and magazines virtually anywhere, and you can leverage your existing collection if you already run Glock pistols. The Gen 3 also opens up serious customization potential—the modular design accepts aftermarket parts and optic mounts to suit your mission. One 10-round magazine ships with the rifle, along with a cleaning kit, cable lock, and user manual, so you're ready to go straight out of the box.

The 4140 chrome-moly barrel wears a Black Nitride (QPQ) finish for durability and low maintenance. Whether you're a 45 ACP devotee, a home-defense builder, or a pistol-caliber rifle enthusiast looking for something genuinely agile, the Vector CRB Gen 3 delivers precision engineering and user-friendly features in a form factor that doesn't compromise on capability.
