The Kriss USA Vector CRB G2 is a semi-automatic carbine chambered in .45 ACP, built around Kriss's Super V Recoil Mitigation system and a delayed blowback action. The MultiCam Flat Dark Earth finish covers the receiver and furniture. The stock is 6-position adjustable, extending overall length from 35.25 to 38.25 inches. Low-profile flip sights are included and the ambidextrous safety is reachable from either side.

Features 

 
The Super V system redirects bolt travel downward rather than rearward, which reduces muzzle rise during firing. The delayed blowback action handles .45 ACP pressures reliably and the pivoting single-stage trigger has a cleaner break than typical blowback pistol-caliber carbines. The 6-position stock lets shooters of different builds find a consistent cheek weld. Low-profile flip sights stow flat when a magnified optic is mounted.

The Vector CRB G2 in .45 ACP MultiCam FDE generates a lot of discussion because the platform is genuinely unusual. Most owners who buy it know what they are getting into, and the recoil mitigation system lives up to Kriss's claims: the rifle stays flat during firing in a way that surprises people used to traditional blowback PCCs.

Accuracy at close to medium distances is consistently rated positively. The .45 ACP cartridge at carbine velocities does what it is supposed to do, and the trigger on the G2 is an improvement over earlier versions.

Weight and bulk come up as trade-offs. At 8 lbs the Vector is heavier than many pistol-caliber carbines, and the overall silhouette is wide, which some users find awkward indoors. Price is another recurring topic; the rifle sits above most competing PCCs, which pushes buyers to justify the cost against the recoil system and aesthetics.

Accessory availability has been a friction point for some owners. The platform's unconventional geometry means standard AR accessories often don't transfer directly, and Kriss-specific options can be harder to source or cost more.
