The Kriss USA Vector CRB G3 in 45 ACP is a 16-inch closed-bolt, delayed-blowback rifle built for shooters who want modern ergonomics and .45 ACP performance in a compact, handy platform. The G3 Vector CRB delivers the distinctive operating characteristics that make Kriss rifles stand out: reliable, controllable shooting with reduced felt recoil and muzzle rise, all in a lightweight, 7.7-pound package that's genuinely easy to handle. Whether you're setting up a suppressed home-defense rifle, running a dedicated pistol-caliber match gun, or just want a fun, accurate .45 to run at the range, the Vector CRB brings serious engineering and proven Kriss reliability to the table.
The 16-inch barrel, threaded .578×28 RH, pairs with a full-length alphanumeric rail system for optics and accessories. The ambidextrous telescopic folding stock lets you dial in your length of pull and collapse the rifle for storage or transport—especially useful if you're cramming gear into a truck or bag during a field day. The design is uncluttered and purposeful: single-stage pivoting trigger, semi-automatic closed-bolt action, and all the controls you'd expect from a modern rifle, tuned for quick, intuitive manipulation.
One 30-round magazine ships with the rifle, giving you solid capacity out of the box. The barrel is 4140 chrome-moly steel with a hard, corrosion-resistant black nitride finish (QPQ process)—a real material choice, not a cosmetic coat. Alpine finish matches the current Kriss aesthetic and blends well in most settings. At just 7.7 pounds, the Vector CRB is light enough to run all day without fatigue, yet substantial enough to feel solid and handle recoil well.
If you've been curious about delayed-blowback operation or just want a .45 ACP rifle that handles like a rifle and shoots smooth, the Kriss Vector CRB G3 is worth a serious look.

Its delayed-blowback system and compact folding design make it versatile for training and field use.
Yes. The barrel is threaded .578×28 RH, a standard thread pitch for .45 ACP suppressors. You'll need a suppressor rated for .45 ACP and compatible with that thread pitch.
The rifle comes with a Kriss ambidextrous telescopic folding stock. It collapses to 34.9 inches overall and extends to 36.9 inches, allowing you to adjust length of pull and make the rifle significantly more compact for transport or storage.
