Description
The KRISS USA VECTOR CRB .22 LR 16″ DUO 10+1 is a semi-automatic rimfire rifle built for shooters who want to train with the iconic Vector platform without burning expensive centerfire ammo. This direct blowback carbine chambers .22 LR, ships with two 10-round magazines, and features a 16″ barrel, ambidextrous folding stock, and M-LOK handguard. It’s a purpose-built trainer that mirrors the handling of its larger-caliber siblings at a fraction of the cost per round.

Key Features
- Ambidextrous Folding Stock – WHY IT MATTERS: The stock folds to the right for compact storage and adjusts from 34.5″ to 37.7″ overall length, letting you dial in length of pull for prone, barricade, or offhand shooting.
- 16″ Barrel with Direct Blowback Action – WHY IT MATTERS: The 16″ barrel delivers consistent velocity for .22 LR accuracy out to 100 yards, while the simple blowback system eats any standard-velocity or high-velocity load without complaint.
- Two 10-Round Magazines Included – WHY IT MATTERS: You get two mags out of the box, so you can load one while shooting the other — critical for stage prep or plinking sessions without stopping to reload.
- Aluminum M-LOK Handguard – WHY IT MATTERS: Mount a bipod, light, or handstop directly to the handguard using M-LOK accessories, keeping your support hand stable and your setup modular for competition or training.
- Full-Length Picatinny Top Rail – WHY IT MATTERS: The continuous top rail lets you mount optics with zero cantilever issues — ideal for red dots, LPVOs, or even a magnified rimfire scope for precision work.
Who It’s For
This rifle is for competition shooters who want to train transitions, reloads, and positional shooting on a .22 LR platform that matches the ergonomics of a centerfire Vector. It’s also perfect for small-game hunters looking for a lightweight, quiet carbine, and for shooters who want to introduce new shooters to the Vector platform with low recoil and low cost per pull.
Pros / Cons
- Pro: Extremely reliable with bulk .22 LR ammo — the direct blowback action cycles everything from CCI Mini-Mags to cheap bulk pack without hiccups.
- Pro: Ambidextrous controls (charging handle, safety, mag release) make it genuinely lefty-friendly.
- Pro: Folding stock reduces storage length to under 27″ — fits in a range bag or backpack.
- Con: The stock feels slightly wobbly when extended — it’s a polymer lock-up, not a solid fixed stock. A small trade-off for the foldability.
- Con: The trigger is a standard mil-spec-style single-stage with some creep — expect 6-7 lbs pull. Aftermarket trigger upgrades exist but aren’t drop-in.

Frequently Asked Questions
Does the KRISS Vector CRB .22 LR accept aftermarket triggers?
Yes, but it uses a proprietary trigger pack design, not standard AR-15 triggers. Several aftermarket companies make drop-in triggers specifically for the Vector .22 LR platform, but verify compatibility before purchasing.
Can I use high-velocity .22 LR ammo in this rifle?
Absolutely. The direct blowback action is designed to handle standard-velocity, high-velocity, and even hyper-velocity loads. Stick with copper-plated rounds for best reliability in the magazines.
Is the folding stock legal in all states?
No. Some states (e.g., New York, California, Massachusetts) have restrictions on folding stocks or overall length. Check your local laws before ordering. The stock folds to the right, so it’s not a pistol grip issue, but overall length with stock folded may matter in some jurisdictions.
How does the Vector CRB .22 LR compare to the 9mm version?
The .22 LR version uses a simple blowback action instead of the KRISS Super V system found in centerfire models. That means less recoil reduction but also lower cost and lighter weight. Ergonomics and controls are nearly identical, making it an excellent trainer for the 9mm or .45 ACP Vector.
What optics mount best on the Picatinny rail?
Any standard Picatinny-compatible red dot, holographic, or scope works. The rail is full length (about 12″), so you can co-witness iron sights or mount a magnifier behind a dot. Popular choices include the Vortex Crossfire red dot, Holosun 510C, or a 1-4x LPVO for precision.
