The Kriss Vector CRB Gen II is a semi-automatic rifle chambered in .40 S&W with a 16-inch barrel. It runs on a delayed blowback action paired with the company's Super V recoil mitigation system, which redirects bolt carrier energy downward to reduce muzzle rise. Overall length is 36.38 inches, weight is 8 lbs, and capacity is 15+1. The FDE finish comes with low-profile adjustable flip sights.

Detailed Features 

The delayed blowback system holds the bolt locked until after the bullet has left the barrel, which improves consistency and helps with follow-up shot accuracy. The Super V system channels recoil mass downward through the grip frame rather than straight back, keeping the muzzle from climbing during rapid fire. The pivoting single-stage trigger has a short travel distance with a defined break. Flip-up sights are adjustable and fold flat when you want to mount optics. 
 

Usage Scenarios 

The Vector works well in competition formats that allow pistol-caliber carbines, particularly where fast target transitions matter. The .40 S&W chambering offers more energy than 9mm at the cost of slightly higher perceived recoil, though the Super V system keeps that manageable. It also fits home defense use where overpenetration concerns favor pistol-caliber rounds over rifle rounds.

The Kriss Vector CRB Gen II gets a mixed but largely positive reception. The recoil mitigation system is the most-discussed feature. Most owners agree that muzzle rise during rapid fire is noticeably reduced compared to conventional blowback designs, and that this translates to better split times.

The FDE finish gets positive comments for appearance and durability. Accuracy and reliability are generally well-regarded, with owners noting solid performance across multiple range sessions.

On the critical side, weight comes up regularly. At 8 lbs the Vector is on the heavier end for a pistol-caliber carbine, which some shooters find tiring during extended use or makes it feel less handy in tight spaces. The .40 S&W caliber draws debate. Its stopping power is appreciated, but several owners note that 9mm is cheaper to shoot and more widely stocked, which affects how often they take it to the range.

Buyers tend to recommend it for shooters who specifically want the Vector's delayed-blowback operating system or the FDE aesthetic, but suggest thinking through caliber availability and weight before committing.
