Kriss Usa Vector Crb G3 45Acp 16 Alpine 10Rd Ca
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. Chambered in 45 ACP and featuring a 16-inch barrel, this Alpine-finished rifle combines the ballistics of a trusted handgun round with the ergonomics and accuracy of a long gun—ideal for home defense, tactical training, or anyone exploring the capabilities of pistol-caliber carbines.
Built on a closed-bolt delayed blowback operating system, the Vector CRB G3 delivers reliable, smooth cycling while keeping recoil manageable. The 4140 chrome-moly barrel is finished in Black Nitride (QPQ) for corrosion resistance and durability in the field or at the range. A pivoting single-stage trigger keeps the action crisp and predictable, while the fixed stock provides a solid, repeatable cheek weld. At 7.7 pounds, it's light enough to handle all day without fatigue, and the 34.9-inch collapsed length makes it convenient for vehicle storage or tight spaces.
The Vector CRB comes ready to shoot with one 10-round magazine—California-compliant for shooters in restricted states. The barrel is threaded .578x28 RH, so you can add a suppressor or muzzle device to fine-tune the platform to your needs. Whether you're setting up a truck gun, expanding your 45 ACP ecosystem, or exploring what a dedicated pistol-caliber carbine can do, the Vector CRB G3 delivers purpose-built performance without compromise.

Frequently Asked Questions
What is the Vector CRB G3 best used for?
The Vector CRB G3 excels as a home defense carbine, truck gun, or training platform for shooters who want the stopping power of 45 ACP with the control and accuracy of a rifle-length sight radius. Its compact size and pistol-caliber round make it practical for confined spaces and reduced overpenetration concerns compared to rifle rounds.
Can I add a suppressor or muzzle brake to this carbine?
Yes. The barrel is threaded .578x28 RH, so you can install a compatible suppressor, muzzle brake, or other threaded accessories to match your shooting goals and preferences.
What comes in the box?
The Vector CRB G3 includes one 10-round magazine and is ready to shoot out of the box. Additional magazines and accessories are sold separately.
Why is this a pistol-caliber carbine instead of a rifle-caliber platform?
A pistol-caliber carbine like the Vector CRB extends the range and power of your 45 ACP ammunition, lets you leverage existing handgun ammo and magazines for economy, and delivers lighter recoil and muzzle signature than centerfire rifle rounds—useful for training, home defense, and follow-up shot speed.
