Description
Nothing else on the rack looks or shoots like a Vector. The KRISS Vector CRB Gen 3 in .45 ACP runs the patented Super V recoil mitigation system, a delayed blowback action that sends bolt energy downward instead of straight back into your shoulder. Pair that with a bore axis that sits below the fire control group, basically in line with your knuckles, and muzzle rise all but disappears. Big-bore .45 out of a 16-inch barrel with that little movement makes for quick follow-up shots and a grin you cannot wipe off at the range.
What Gen 3 Changed on the Vector CRB
KRISS did real homework on this generation. The housings got slimmer and lighter, the old railed shroud gave way to a cleaner M-LOK barrel shroud for lights and accessories, and the trigger was reworked with a skeletonized flat-faced design that cuts pre-travel way down from the Gen 2. The charging handle is shorter, non-reciprocating, and folds out of the way, the magazine release is reversible, and the bolt lock got reshaped for easier use. A full-length Picatinny top rail handles optics, and low-profile flip-up sights come installed so you can shoot it the day it comes home.
Vector CRB Gen 3 Setup and Feeding
This model wears a durable Ironwood Delta camo Cerakote finish and comes configured with a fixed stock and blade-style grip. The 16-inch barrel is threaded 1/2 the usual way KRISS does it, .578×28, ready for a muzzle device when you are. Feeding comes from Glock 21 pattern magazines, one of the most common and affordable mag platforms out there, and a 10-round magazine ships in the box. Takedown is simple too, just a handful of pins and no tools required, so cleaning after a long range day is painless.
Between the sci-fi profile, the flat-shooting Super V action, and the Gen 3 refinements, this carbine earns its spot as a favorite for range days, PCC matches, and home defense duty alike.

Frequently Asked Questions
What magazines does the KRISS Vector CRB Gen 3 in .45 ACP use?
It feeds from standard Glock 21 pattern .45 ACP magazines, which are affordable and easy to find just about anywhere. This model ships with one 10-round magazine in the box. The Gen 3 also has a reversible magazine release, so left-handed folks can set it up their way.
What is different about the Gen 3 Vector compared to Gen 2?
Gen 3 brought a slimmer, lighter housing, an M-LOK barrel shroud in place of the old Picatinny shroud, and a much improved skeletonized trigger with dramatically reduced pre-travel. KRISS also shortened the folding charging handle, reshaped the bolt lock, and made the mag release reversible. It keeps the same Super V action the Vector is known for, just with better ergonomics all around.
How does the Super V system actually reduce recoil?
Instead of the bolt driving straight back at your shoulder, the Super V system redirects that energy downward into a recess behind the magazine well. Combined with a bore axis that sits below the trigger, roughly in line with your middle knuckle, muzzle rise is minimal even with .45 ACP. The result is a carbine that stays flat and lets you stack fast follow-up shots.
Is the barrel on the Vector CRB Gen 3 threaded for a muzzle device?
Yes, the 16-inch barrel comes threaded in .578×28, the standard thread pitch for .45 caliber muzzle devices. That gives you plenty of options for a brake, compensator, or other muzzle accessories down the road. Flip-up sights and a full-length top rail round out the setup for optics.
