The Kriss Vector CRB G3 is a pistol-caliber carbine chambered in .45 ACP with a 16-inch barrel, built for use in states that restrict shorter configurations. It runs on Kriss's closed-bolt delayed-blowback operating system and uses full-size Glock-style magazines. This example has a Woodland Cerakote finish over the carbine's redesigned upper and lower housings.

Vector owners consistently praise the delayed-blowback system for taming felt recoil in .45 ACP, and most describe the carbine as very soft-shooting for the caliber. Complaints center on the price relative to competing PCCs and on the folding stock's fit and finish varying between units.

The ambidextrous controls and adjustable folding stock draw praise for making the Vector comfortable for both right- and left-handed shooters, though some find the overall package front-heavy compared to AR-style PCCs. The M-LOK shroud makes it easy to add lights or forward grips.

Buyers like that it runs Glock-pattern magazines, since that keeps ammo capacity flexible and taps into a wide magazine aftermarket. The carbine sits at a premium price point, so some owners weigh it against AR-9 style PCCs before buying.
