Description
There is nothing else on the rack that runs like a KRISS Vector. Instead of a bolt slamming straight back into your shoulder, the Super V system redirects recoil energy down and behind the magwell, which keeps the muzzle remarkably flat between shots. Pair that with a closed-bolt delayed blowback action and a 16 inch barrel squeezing extra velocity out of 9mm, and you get a carbine that stacks fast follow-up shots with almost no climb. That is exactly why these keep showing up in PCC divisions.
What Gen 3 Brings to the Vector CRB
The third generation is a meaningful update, not just a fresh coat of paint. KRISS reworked the upper and lower housings for better ergonomics, added a redesigned bolt release and mounting block, and fitted a low profile upper with a full length Picatinny top rail. The new square barrel shroud carries M-LOK slots on both sides and along the bottom, so lights, lasers, and hand stops bolt right on. Controls are properly ambidextrous too, with a short throw safety lever and a reversible magazine release, plus an interchangeable AR-15 style pistol grip if you want to swap in your favorite. Flip-up front and rear sights come installed, and the 1/2×28 threaded muzzle is ready for your choice of muzzle device or suppressor.
Feeding the Vector CRB Gen 3
Magazines are a big part of the appeal here. The Vector feeds from full size Glock pattern mags, which are cheap, plentiful, and probably already in your range bag. This model ships with a 40 round extended magazine, so you can shoot a full stage or a long plinking string without a reload. The 3-position folding stock adjusts for length of pull and folds flat for compact storage, and the whole gun breaks down with four pins and no tools, making cleanup after a range day quick and painless. At 7.7 pounds with that distinctive Vector profile, it handles like nothing else in the safe, and that is half the fun.

Frequently Asked Questions
What magazines does the KRISS Vector CRB G3 use?
It feeds from full size Glock pattern 9mm magazines, the same ones used by the Glock 17. That means factory Glock mags, aftermarket options, and extended magazines all work. This model ships with one 40-round extended magazine in the box.
How does the Super V system reduce recoil?
Instead of the bolt traveling straight back, the Super V mechanism redirects the bolt's energy downward behind the magazine well. That off-axis movement cuts felt recoil and muzzle rise noticeably compared to a standard straight blowback 9mm carbine. The result is a flatter shooting gun with quicker follow-up shots.
Can I mount a suppressor on the Vector CRB Gen 3?
Yes, the 16 inch barrel comes threaded 1/2×28 RH, which is the standard pitch for most 9mm suppressors and muzzle devices. The closed bolt operating system also tends to run well suppressed. Just thread on your can or brake of choice.
What is different about the Gen 3 Vector compared to Gen 2?
Gen 3 brings redesigned upper and lower housings, a low profile upper with full length Picatinny rail, an updated bolt release, and a new square barrel shroud with M-LOK slots on the sides and bottom. Controls are fully ambidextrous with a short throw safety and reversible mag release. It also accepts standard AR-15 pistol grips, so customizing the grip is simple.
