Description
There is no mistaking a Vector for anything else on the rack. The Kriss Vector CRB Gen 3 pairs that unmistakable silhouette with real engineering underneath: the Super V Recoil Mitigation System, a delayed blowback action that sends bolt energy down and away instead of straight back into your shoulder. Combine that with a barrel that sits below the fire control group, in line with your second knuckle, and you get a 45 ACP carbine that stays remarkably flat when you run it fast. Big-bore thump without the big-bore muzzle rise is the whole point of this platform, and it delivers.
What Gen 3 Brings to the Vector CRB
This third generation is the most refined Vector yet. The redesigned upper and lower housings accept standard AR-pattern pistol grips, the magazine release is ambidextrous and reversible, and the trigger got a serious cleanup with a short, crisp take-up. The barrel shroud now carries M-LOK slots on the sides and bottom for lights and hand stops, and a full-length Picatinny top rail leaves plenty of room for a red dot or magnifier combo. The folding, telescoping stock collapses the whole package down for easy transport, and four-pin tool-less disassembly makes cleaning day quick.
Feeding and Finish on This 45 ACP Carbine
Like every Vector, the CRB runs on full-size Glock 21 pattern magazines, so mags are affordable and everywhere. This model ships with one 10-round magazine and wears the sharp Woodland Delta Cerakote camo over a 16 inch 4140 chrome moly barrel with a black nitride finish and .578×28 threaded muzzle. Low-profile flip-up sights come installed, so it is range ready out of the box.
Whether you are chasing PCC match times, plinking on the weekend, or just want the carbine everyone at the range asks about, the Vector CRB Gen 3 earns its spot. It is a genuinely different way to shoot 45 ACP, and once you feel how flat it runs, it is hard to go back.

Frequently Asked Questions
What magazines does the Kriss Vector CRB Gen 3 in 45 ACP use?
It feeds from full-size Glock 21 pattern 45 ACP magazines, which keeps spares affordable and easy to find. One 10-round magazine comes in the box. If you already run a Glock 21, your mags will drop right in.
Does the Super V system really reduce recoil?
It does, and it is noticeable the first time you shoot one. Instead of driving bolt energy straight back, the Super V system redirects it downward, which counteracts muzzle rise. Paired with a bore axis that sits below the trigger group, the Vector runs flatter than most 45 ACP carbines, making fast follow-up shots much easier.
Is the barrel on this Vector CRB threaded for a suppressor?
Yes, the 16 inch black nitride barrel is threaded .578×28 RH, the standard pattern for 45 caliber muzzle devices and suppressors. The 45 ACP round is also naturally subsonic with standard 230 grain loads, which makes this one of the more satisfying hosts to run suppressed.
What is new on the Gen 3 Vector compared to Gen 2?
Kriss made meaningful updates across the board. Gen 3 adds a folding, telescoping stock, an M-LOK barrel shroud, an improved trigger with shorter take-up, an ambidextrous reversible magazine release, and housings that accept standard AR-pattern pistol grips. It also keeps the four-pin tool-less disassembly, so maintenance stays simple.
