The Kriss USA Vector CRB G3 9mm is a modern take on an iconic platform that brings submachine gun ergonomics and reliability to a civilian rifle form. This 16-inch barreled variant chambers 9mm and ships with a 40-round magazine—giving you plenty of rounds downrange without the weight penalty of larger calibers. Whether you're setting up a dedicated 9mm for home defense, competition, or just enjoying affordable high-volume shooting, the Vector's unconventional design philosophy delivers controllability and modularity that serious shooters appreciate.
The closed-bolt delayed blowback operating system is the heart of the Vector's appeal. Unlike many direct-impingement or short-stroke piston designs, this system keeps the bolt in battery, offering consistent firing characteristics and reduced felt recoil—especially notable in 9mm. The ambidextrous telescopic folding stock adapts to different shooting positions and storage scenarios, while the 1/2x28 threaded barrel opens up aftermarket muzzle device options. At 7.7 pounds and collapsible to 34.9 inches, it's compact enough for tactical setups without sacrificing a full-length sight radius.
Built with a 4140 chrome moly barrel finished in black nitride (QPQ process), the Vector is engineered for durability. The pivoting single-stage trigger provides a predictable break, and the overall design emphasizes reliability over trend-chasing. This is a rifle that works as hard as you do, whether at the range, in competition, or in a home defense role where 9mm ballistics and barrier-blind capability matter.

Frequently Asked Questions
Is the Vector CRB G3 compatible with suppressors?
Yes. The barrel is threaded 1/2 x 28 RH, which is the standard thread pitch for 9mm suppressors. You can attach any suppressor with that specification.
What magazine does the Vector CRB G3 use?
It ships with one 40-round magazine. Always verify compatibility with your specific build, but standard 9mm magazines designed for the Vector platform are readily available.
Can I fold the stock, and will it change the overall length significantly?
Yes, the ambidextrous telescopic folding stock collapses the rifle to 34.9 inches from 36.9 inches when extended. This makes it easier to transport or store in tight spaces while maintaining full functionality when deployed.
What's the weight, and is it manageable for extended shooting?
The Vector CRB G3 weighs 7.7 pounds, which is reasonable for a 9mm rifle platform. Combined with the closed-bolt delayed blowback system that reduces felt recoil, most shooters find it comfortable for extended range sessions or training.
