The KRISS Vector Gen II CRB is a semi-automatic rifle chambered in .40 S&W with a 16-inch barrel. Its defining feature is the KRISS Super V Recoil Mitigation System, which redirects bolt mass downward to reduce muzzle rise and keep follow-up shots on target. The rifle ships in Black Cerakote and runs on Glock G22 magazines.

Features 

 
The Super V system aligns the bore axis closer to the shooter's arm, which is where the recoil reduction comes from, particularly noticeable during rapid fire. Caliber conversion is tool-free, so swapping between compatible calibers doesn't require a gunsmith. The full-length MIL-STD 1913 Picatinny top rail accepts standard optics and sights. The design takes standard Glock double-stack .40 S&W magazines, which are widely available.

Users of the KRISS Vector Gen II CRB in .40 S&W tend to be enthusiastic about its design, though practical concerns do come up.

The recoil mitigation system is the most discussed feature, and most owners confirm it delivers. Controlled shooting, especially during rapid fire, is noticeably better than conventional platforms. The Black Cerakote finish gets positive remarks for its appearance and durability. Versatility is a recurring theme: owners mention home defense, competitive shooting, and recreational range use as the main reasons they chose it, and the .40 S&W caliber generates ongoing debate about stopping power versus the lighter recoil of 9mm.

On the critical side, weight and bulk come up frequently. At 8 lbs the rifle is heavier than many comparable platforms, and some users find it awkward in tight spaces. Magazine availability and cost are also mentioned. While Glock G22 compatibility helps on the availability front, proprietary magazine costs relative to more common formats is a recurring complaint.
