The Kriss USA Vector CRB G3 in 45 ACP is a semi-automatic carbine built for shooters who want serious stopping power in a compact, controllable platform. This 16-inch barreled rifle uses Kriss's proven closed-bolt delayed blowback operating system to manage the heavy recoil of .45 ACP, delivering smooth, manageable shooting dynamics whether you're at the range, running defensive drills, or working within California's restrictions. With its flat dark earth finish and fixed stock, the Vector CRB G3 cuts an understated profile while packing genuine punch downrange.
The Vector's design philosophy centers on taming big-bore recoil without sacrificing reliability. The delayed blowback system is the secret—it cycles the action in a way that spreads recoil impulse over a longer stroke, so follow-up shots stay on target and fatigue stays lower than you'd expect from a .45 ACP carbine. The barrel is forged 4140 chrome moly steel with a black nitride finish for durability, and it's threaded .578x28 RH if you want to suppress or add muzzle devices down the road. The single-stage trigger is clean and predictable, and the included 10-round magazine ships loaded and ready to test.
This is a California-compliant configuration, making it a practical choice if you're in a restricted state and don't want to compromise on capability. The Vector has earned respect in self-defense, law enforcement training, and hardcore shooting circles—it's not a casual plinker, it's a legitimate tool that happens to shoot one of the ballistically proven defensive cartridges in existence.

What's included in the box?

What makes the delayed blowback system different?
The closed-bolt delayed blowback operating system spreads the recoil impulse over a longer action cycle than traditional direct blowback, resulting in softer recoil and faster follow-up shots—a significant advantage when shooting .45 ACP, a cartridge known for sharp recoil in most platforms.
