Description
There is nothing else on the wall that looks or shoots like a KRISS Vector. This CRB G2 takes the .45 ACP cartridge, a round known for pushing pistols around, and turns it into a soft, flat-shooting carbine experience. The trick is the Super V system, a nonlinear delayed blowback design that sends the bolt down and back behind the magazine well instead of straight into your shoulder. Combine that with a bore axis that sits almost in line with your hand and you get a gun that barely moves between shots. Fast pairs on steel feel almost unfair.
What the Gen 2 Vector CRB Brings to the Table
The G2 update refined the platform where it counts. You get a more comfortable pistol grip, a reworked single-stage trigger, and a short-throw ambidextrous safety that falls right under your thumb. The 16 inch barrel is 4140 chrome moly steel with a black nitride finish, threaded at the muzzle, and spun with a 1:10 twist that stabilizes everything from 185 grain match loads to 230 grain ball. Flip-up front and rear sights come installed, and the full-length Picatinny top rail leaves plenty of room for a red dot or magnifier setup.
Feeds from Glock Mags, Built to Run
Magazine compatibility is one of the smartest parts of the Vector design. It runs on full size Glock 21 magazines, so sticks are cheap, proven, and everywhere, including extended options when a 13 rounder is not enough. The aluminum receiver keeps the chassis rigid while the polymer furniture keeps overall weight around 8 pounds, and the 6-position M4-style stock adjusts from 35.25 to 38.25 inches overall to fit just about any build or armor setup.
Why This FDE Vector Carbine Earns Its Spot
The Flat Dark Earth finish covers the receiver and furniture for a clean, matched look that stands out from the sea of black rifles. Whether you are running PCC matches, burning through range ammo on the weekend, or you just want the closest thing to a sci-fi prop that runs like a Swiss watch, the Vector CRB G2 delivers a shooting experience you will not find anywhere else. Each carbine ships with one 13 round magazine, cable lock, cleaning brush, and manual.

Frequently Asked Questions
What magazines does the KRISS Vector CRB G2 in .45 ACP use?
It feeds from full size Glock 21 pattern .45 ACP magazines, and one 13 round mag comes in the box. Since Glock mags are inexpensive and easy to find, stocking up is painless, and extended options are available if you want more capacity for matches or range days.
Does the Super V system really reduce recoil?
It makes a noticeable difference. Instead of a standard straight blowback bolt slamming rearward, the Vector's bolt travels down and back behind the magazine well, redirecting recoil energy away from your shoulder. Paired with the low bore axis, muzzle rise with .45 ACP is impressively tame, which is exactly why the platform has such a strong following in pistol caliber carbine competition.
Is the barrel on this Vector CRB threaded for a suppressor or muzzle device?
Yes, the 16 inch black nitride barrel comes threaded from the factory, so you can add a compensator, brake, or suppressor mount. And since .45 ACP is naturally subsonic with standard 230 grain loads, this carbine is a popular host for suppressed shooting.
Can I mount a red dot on the Vector CRB G2?
Absolutely. The full-length Picatinny top rail gives you plenty of real estate for a red dot, holographic sight, or magnifier combo. The included flip-up front and rear sights fold down out of the way and can serve as backups once your optic is zeroed.
