Description
There is nothing else on the rack that runs like a KRISS Vector. The CRB G2 in .45 ACP uses the Super V system, a delayed blowback action with a bolt that travels down and back instead of straight rearward. That redirects recoil energy below the bore, and combined with the Vector's naturally low bore axis, muzzle rise all but disappears. Fast follow up shots with .45 ACP feel more like plinking with a rimfire than running a big bore carbine, which is exactly why these have become a favorite in pistol caliber carbine matches and a blast at any range day.
What Sets the Vector CRB G2 Apart
This G2 version wears a MultiCam Black Camo Cerakote finish over the polymer shell, and it looks as sharp in person as it does in photos. The 16 inch 4140 chrome moly barrel gets a black nitride treatment and comes threaded, with a 1:10 right hand twist that stabilizes everything from soft shooting 230 grain range loads to lighter defensive stuff. The two stage quick reset trigger is a real bright spot on the G2 generation, breaking clean and letting you run splits quickly. A six position adjustable stock dials in your length of pull, and low profile flip up sights sit on the full length Picatinny top rail, ready to go out of the box or easy to fold down under an optic.
Glock Mag Compatibility Done Right
The Vector CRB feeds from full size Glock .45 ACP magazines, and this model includes one 30 round extended mag. That means cheap, proven, widely available magazines instead of expensive proprietary ones, and if you already own a Glock 21 you have spares sitting in your safe right now.
Living With the Vector CRB G2
At 8 pounds with an overall length between 35.25 and 38.25 inches depending on stock position, it handles like a compact carbine should. The closed bolt design keeps it consistent and accurate, and the futuristic layout is more than looks; the controls are laid out well and the whole package balances nicely between the hands. If you want a .45 ACP carbine that genuinely does something different, this is the one.

Frequently Asked Questions
What magazines does the KRISS Vector CRB G2 in .45 ACP use?
It runs full size Glock .45 ACP magazines, the same pattern used by the Glock 21. This model ships with one 30 round extended magazine, and standard 13 round Glock mags work as well. That keeps spare mags cheap, proven, and easy to find compared to proprietary designs.
Does the Super V system really reduce recoil that much?
It makes a noticeable difference. Instead of driving straight back into your shoulder, the bolt travels down and rearward, redirecting recoil energy below the bore. Paired with the Vector's low bore axis, muzzle climb is minimal even with full power 230 grain .45 ACP, which is why these are so popular for fast paced PCC shooting.
Can I mount an optic on the Vector CRB G2?
Yes, there is a full length Picatinny rail up top, and the included flip up sights fold down low so they stay out of the way. Red dots are the most common pairing on Vectors since the flat shooting action rewards a fast dot. You can also cowitness the irons with many mounts if you like a backup.
Is the barrel on the Vector CRB G2 threaded?
It is. The 16 inch 4140 chrome moly barrel comes threaded from the factory with a durable black nitride finish, so adding a muzzle device down the road is simple. The 1:10 twist rate handles common .45 ACP bullet weights without any fuss.
