The KRISS Vector CRB Gen II is a semi-automatic pistol caliber carbine chambered in .40 S&W, offered here in a California-compliant configuration with a fixed stock and a 10-round magazine. It runs on KRISS's Super V delayed blowback system, which redirects recoil down through a nonlinear multi-link mechanism and keeps the bore axis low. The carbine has a 16-inch barrel and feeds from Glock-pattern magazines.

Owners of the Vector CRB Gen II generally like how the closed-bolt Super V delayed blowback action shoots softer than a straight-blowback PCC, though a few point out that the mechanism is more involved to strip and clean than a simple blowback gun, and parts support leans on KRISS directly rather than a broad aftermarket.

The low bore axis draws consistent praise for keeping the carbine controllable and easy to run for a PCC, but the fixed stock on this California-compliant Vector CRB is seen as a step down from KRISS's folding and adjustable stock options, and a few owners find the fixed-stock version bulkier to store or transport.

Glock-pattern magazine compatibility is a common point of satisfaction since it keeps magazines affordable and easy to source. Opinions on the cost of the Vector platform itself are more mixed, with some owners feeling it's worth the premium for the recoil system and others thinking a standard AR-pattern PCC gets close for less.
