The Kriss USA Vector CRB Gen3 Semi-Auto Rifle is the most versatile and competition-ready Kriss Vector yet. Engineered for pistol-caliber carbine competitions, the Kriss Vector Gen3 features a compliant barrel length as well as a redesigned upper and lower housing for improved ergonomics and easier customization. The newly redesigned barrel shroud features integrated M-LOK mounting slots for more accessory mounting options. That said, the Kriss Vector CRB Gen3 operates on the same fundamental principles as previous models. It still operates via the Super V System a non-linear, multi-link blowback system that redirects recoil impulse downward instead of rearward. This downward movement of the bolt helps counteract muzzle lift during high rates of fire, keeping you on-target for follow-up shots. It's what makes the Vector one of the easiest-to-control firearms in the world. Of course, like prior models, the Gen3 still accepts GLOCK double-stack magazines. 4140 chrome moly steel barrel with threaded muzzle Redesigned upper and lower housing for enhanced ergonomics Newly redesigned barrel shroud with integrated M-LOK slots Accepts GLOCK double-stack 9mm magazines Super V System for easy control Single-stage trigger Ambidextrous, telescopic folding stock
