Description
The KRISS Vector has always stood out for the way it shoots, and the Gen 3 CRB takes that reputation and dials in the ergonomics. This 9mm pistol-caliber carbine runs the patented Super V Recoil Mitigation System, a delayed blowback design that drives the bolt down and back into the frame instead of straight to the rear. Pair that with a bore axis that sits below the trigger, and you get a carbine that barely moves between shots. If you've never run a Vector, the first mag tends to make the point for you.
What Sets the Vector CRB Gen 3 Apart
The Gen 3 housings are the big story here. The upper and lower were reworked to accept an interchangeable AR-style pistol grip, so you can set the grip up the way you like it. The receiver also adds a MIL-STD 1913 Picatinny stock mount and improved texturing around the magwell for a more positive hold. Up front, the refreshed M-LOK barrel shroud gives you plenty of real estate for lights, lasers, or a hand stop, and the full-length top rail leaves room for whatever optic you want to bolt on.
Built for the Range and PCC Matches
The 16-inch barrel is 4140 chrome moly with a black nitride (QPQ) finish, and it's threaded 1/2×28 so adding a suppressor or compensator is a simple job. It feeds from full-size Glock-pattern magazines and ships with a 40-round stick, which keeps you shooting between reloads. The skeletonized trigger and ambidextrous magazine release round out a package that feels right whether you shoot lefty or righty.
Ironwood Delta Camo and a Folding Stock
This one wears a Cerakote Ironwood Delta camo finish that looks sharp and holds up to range abuse. The KRISS ambidextrous telescopic folding stock adjusts to fit and folds down for compact storage and transport. At roughly 7.7 pounds, the Vector CRB handles like what it is: a purpose-built 9mm carbine made to turn ammo into grins.

Frequently Asked Questions
What magazines does the Vector CRB Gen 3 use?
The 9mm Vector CRB Gen 3 runs full-size Glock-pattern 9mm magazines. It ships with one 40-round magazine, and standard Glock 17-style and extended mags will drop right in. That makes finding spare mags easy and affordable.
Is the barrel on the Vector CRB Gen 3 threaded?
Yes. The 16-inch 4140 chrome moly barrel is threaded 1/2×28 RH, so you can add a suppressor, compensator, or other muzzle device without any extra gunsmithing. The barrel also wears a black nitride (QPQ) finish for durability.
What makes the Super V system different from a standard blowback carbine?
The Super V Recoil Mitigation System redirects the bolt down and back into the frame rather than straight rearward. Combined with the Vector's very low bore axis, it keeps muzzle rise to a minimum and the gun flat through fast strings of fire. It's a big part of why the Vector feels so controllable compared to typical pistol-caliber carbines.
What's new on the Gen 3 compared to earlier Vector CRB models?
The Gen 3 brings redesigned upper and lower housings that accept an interchangeable AR-style pistol grip and add a Picatinny stock mount. You also get improved magwell texturing for a better grip and a refreshed M-LOK barrel shroud for mounting accessories. It's a more customizable, ergonomic take on the platform.
