Description
There's nothing else on the rack that runs quite like a Vector. The KRISS Vector CRB Gen 3 in 9mm uses the Super V Recoil Mitigation System, a delayed blowback design where the bolt travels down and back into the frame instead of straight rearward. Combine that with a bore axis that sits lower than just about anything else out there and you get a carbine that stays remarkably flat through fast strings of fire. Follow-up shots come quick, and the 16 inch barrel wrings solid velocity and accuracy out of everyday 9mm ammo.
What Gen 3 Brings to the Vector CRB
The third generation is more than a facelift. KRISS reworked the upper and lower housings with reshaped side profiles and fresh texturing on the mag well for a better grip on reloads, and the lower now accepts standard AR-15 pistol grips so you can swap in whatever feels right in your hand. The new barrel shroud carries M-LOK slots on the sides and bottom for lights, hand stops, or a sling mount. You also get an ambidextrous safety, a reversible mag release, flip-up front and rear sights, an adjustable folding stock, and tool-less four-pin disassembly that makes cleanup painless. The muzzle is threaded 1/2×28, so mounting a suppressor or comp is simple.
Feeding the Vector Gen 3 CRB
Magazines are the easy part. The Vector feeds from full-size Glock pattern 9mm mags, which are affordable, everywhere, and proven. This one ships with a 40 round magazine in the box, so you're set for a long stage or an entertaining afternoon right away.
A 9mm Carbine Built for Real Range Work
At 7.7 pounds with an overall length just under 37 inches extended, the CRB handles like a purpose-built PCC because it is one. The Flat Dark Earth finish looks sharp over the black nitride barrel, and the whole package is ready for pistol caliber carbine divisions, training days, or just turning ammo into grins. If you've been curious about the Vector, the Gen 3 CRB is the most refined version yet.

Frequently Asked Questions
What magazines does the KRISS Vector CRB Gen 3 use?
It feeds from full-size Glock pattern 9mm magazines, like those from the Glock 17. That means cheap, reliable mags are available just about everywhere, and if you already run a Glock you can share mags between the two. A 40 round magazine comes in the box.
Is the barrel on the Vector CRB Gen 3 threaded for a suppressor?
Yes. The 16 inch barrel is threaded 1/2×28 RH, which is the standard pitch for 9mm suppressors, compensators, and other muzzle devices. The barrel itself is 4140 chrome moly with a black nitride finish for durability.
What's different about the Gen 3 compared to earlier Vectors?
Gen 3 brings redesigned upper and lower housings with better mag well texturing and improved side profiles, plus compatibility with standard AR-15 pistol grips so you can customize your grip. It also wears a new barrel shroud with M-LOK slots for accessories, along with an ambidextrous safety and reversible mag release. Disassembly is a tool-less four-pin affair, so maintenance is quick.
Does the KRISS Vector really reduce recoil in 9mm?
The Super V system directs bolt mass down and away rather than straight back, and the bore axis sits extremely low relative to your grip. In 9mm the result is a carbine with very little muzzle rise, which is why the Vector is popular in pistol caliber carbine competition where fast, flat follow-up shots matter.
