Description
There is nothing else on the rack that looks or shoots like a Kriss Vector, and the CRB G3 is the most range-friendly version of the platform yet. Chambered in .45 ACP with a 16-inch barrel, this carbine is built around the Super V recoil mitigation system, a delayed blowback design that sends the bolt down and back instead of straight into your shoulder. Pair that with a bore axis that sits about as low as physics allows and you get a big-bore carbine that stays remarkably flat between shots. For PCC matches or just burning through a case of 230 grain ball on a Saturday, it is a genuinely fun gun to run.
What the Gen 3 Update Brings to the Vector CRB
The G3 generation gave the Vector reworked upper and lower housings with better ergonomics, cleaner lines, and improved texture around the mag well. The refreshed square barrel shroud carries M-LOK slots for lights, hand stops, or whatever else you want to bolt on, and the full-length top rail handles optics with room to spare. The 16-inch 4140 chrome moly barrel wears a black nitride finish and comes threaded .578×28, so adding a muzzle device or suppressor down the road is simple. Low-profile flip-up front and rear sights are installed from the factory, controls are ambidextrous, and the fixed polymer stock keeps the whole package solid and consistent from shot to shot.
Glock Magazine Compatibility Makes the Vector G3 Easy to Feed
Like every Vector, this one runs on full-size Glock pattern .45 ACP magazines, and it ships with one 10-round mag in the box. If you already own a Glock 21, your mags drop right in, which keeps range logistics dead simple. At 7.7 pounds with an overall length just under 35 inches, the CRB handles quickly indoors and on stages alike.
Why the Kriss Vector CRB G3 Earns Its Spot
The Flat Dark Earth finish looks sharp against the Vector's angular frame, and the closed-bolt operation delivers the consistency you want when the timer beeps. Distinctive looks, soft-shooting .45 ACP performance, and real modularity make this carbine a standout in the pistol-caliber category.

Frequently Asked Questions
What magazines does the Kriss Vector CRB G3 in .45 ACP use?
It feeds from full-size Glock pattern .45 ACP magazines, the same ones that fit a Glock 21. One 10-round magazine comes in the box, and factory 13-round Glock mags along with Kriss MagEx extension kits are widely available where allowed. That compatibility makes spare mags cheap and easy to find.
Does the Vector really reduce recoil compared to other .45 ACP carbines?
It does, and it is noticeable. The Super V system redirects bolt energy downward instead of straight back, and the barrel sits nearly in line with your shoulder thanks to the very low bore axis. The result is a .45 that stays flat and gets back on target quickly, which is a big part of why the Vector is popular in PCC competition.
Can I put a suppressor or muzzle device on this Vector CRB G3?
Yes. The 16-inch barrel comes threaded in the .578×28 pattern, which is the common thread pitch for .45 caliber suppressors and muzzle devices. Just confirm your accessory matches that thread before mounting it up.
Is the Kriss Vector CRB G3 optics ready?
It ships with low-profile flip-up front and rear iron sights already installed, plus a full-length top rail for mounting red dots, magnifiers, or low-power scopes. The Gen 3 shroud also has M-LOK slots for lights and other accessories, so you can set it up however you like.
