Who It’s For
This rifle is for competition shooters who want affordable trigger time without burning centerfire ammo. It works for USPSA Rimfire Challenge, steel plate matches, and high-volume training. If you’re a precision enthusiast who dials in optics and tracks splits, the Vector CRB gives you a dedicated .22 LR platform with a two-stage trigger and threaded barrel—no compromises.
Pros & Cons
- Pro: 30+1 capacity with two mags—ideal for stage-based shooting where reloads cost time.
- Pro: 5.45 lbs unloaded, so it handles like a full-size rifle but stays light for transitions.
- Con: .22 LR can be finicky with some bulk-pack ammo; you may need to test a few brands for reliable feeding.
- Pro: Two-stage trigger gives a defined wall—similar to high-end AR triggers, but factory-installed.
- Con: Duo configuration means a non-reciprocating charging handle; some shooters prefer a reciprocating handle for visual confirmation.

FAQ
Does the Kriss Vector CRB .22 LR accept standard AR-15 grips and stocks?
No—the Vector CRB uses a proprietary stock and grip interface. The folding stock is ambidextrous and integrated into the receiver, so you cannot swap it for AR-style stocks. However, the M-LOK handguard accepts standard M-LOK accessories.
What is the barrel twist rate on the Vector CRB .22 LR?
The barrel has a 1:16 twist rate, optimized for standard-velocity and high-velocity .22 LR rounds. This twist stabilizes 36- to 40-grain bullets well for plinking and steel targets.
Can I use a suppressor with the threaded barrel?
Yes—the 1/2×28 thread pattern is the standard for .22 LR suppressors. Just ensure the suppressor is rated for rimfire use and that you comply with NFA regulations.
Does the Vector CRB come with a warranty?
According to KRISS USA specs, the Vector CRB is covered by a limited lifetime warranty for the original owner against defects in materials and workmanship. Register your rifle on their website for full details.
What is the difference between the Duo and standard Vector CRB?
The Duo configuration features a non-reciprocating charging handle on the left side, while the standard model has a reciprocating handle. The Duo also includes two 30-round magazines instead of one.
