KRISS Vector CRB G3 16″ .45 ACP Arctic Delta
About this product
The KRISS Vector CRB G3 16″ .45 ACP Arctic Delta is a semi-automatic pistol caliber carbine built for competitive shooting and recreational use with its unique delayed blowback system and 16-inch barrel. Its Gen 3 redesign focuses on improved ergonomics and modularity while maintaining NFA compliance with a fixed 16-inch barrel and telescoping stock. The Arctic Delta finish provides both corrosion resistance and tactical aesthetics without compromising function.
What is the KRISS Vector CRB G3 used for?
This carbine excels in pistol caliber carbine competitions and recreational range shooting where .45 ACP's stopping power matters. Its 16-inch barrel length provides optimal ballistics for the .45 ACP round while keeping the platform legal without NFA paperwork. The M-LOK compatible shroud allows for light, laser, or vertical grip attachments to tailor it for specific competition stages or defensive scenarios.
How does the KRISS Vector CRB G3 compare to the Stevens 334 Rifle?
The Vector CRB G3 offers faster follow-up shots and higher magazine capacity compared to the bolt-action Stevens 334 Rifle chambered in .308 Win. While the Stevens 334 delivers superior long-range accuracy with its 20-inch barrel, the Vector's semi-automatic operation and 13+1 round capacity make it better suited for dynamic shooting sports and rapid engagement scenarios under 100 yards.
What does it weigh and what are the dimensions?
This carbine weighs 7.7 pounds unloaded and measures 34.9 inches collapsed to 36.9 inches extended with its telescoping stock. The 16-inch barrel provides a solid sight radius while the folding mechanism reduces storage length to just 28.5 inches when folded, making it manageable for vehicle transport or range bag storage compared to fixed-stock alternatives.
Who is this NOT for?
This platform isn't ideal for traditional hunters or precision long-range shooters who need rifle-caliber ballistics. The .45 ACP cartridge drops significantly beyond 100 yards, and the 7.7-pound weight makes it heavier than many AR-pattern carbines in smaller calibers. If you're primarily hunting deer or shooting past 200 yards, consider the Stevens 334 in .308 Win instead.
What's in the box?
You receive the complete carbine with one 13-round Glock-pattern magazine, the telescoping folding stock installed, and factory-installed flip-up sights. Unlike some competitors, KRISS includes both a cleaning rod and bore brush specific to the .45 ACP caliber, along with the necessary Allen keys for sight adjustment and rail mounting.
Is the KRISS Vector CRB G3 worth it at $1866.99?
At this price point, it delivers exceptional value for competitive shooters who need the unique Vector recoil mitigation system. The proprietary delayed blowback operation reduces felt recoil by approximately 40% compared to direct blowback PCCs, while the Gen 3 improvements address earlier ergonomic complaints. For the money, you're getting a competition-ready platform that would cost $500+ more to build from an SBR-converted pistol version.

Frequently asked questions
- Is it compatible with Glock magazines?
- Yes, it uses standard full-size Glock-pattern magazines in .45 ACP. The carbine comes with one 13-round magazine and accepts any Glock 21 or 30-series magazine, with aftermarket options available up to 30-round capacity from manufacturers like ETS or Magpul.
- Does the stock lock in both positions?
- The telescoping stock features 5 distinct positions with positive detents and locks securely in both fully collapsed and extended configurations. The folding mechanism uses a robust steel hinge that locks open with a audible click and requires deliberate pressure to release, preventing accidental closure during firing.
- How long does shipping take to Montana?
- Firearms shipping to FFL dealers in Montana typically takes 3-5 business days from our Nevada warehouse. All shipments require signature confirmation and FFL verification, adding approximately 24 hours to the processing time compared to non-restricted items.
- Can I mount a suppressor on this barrel?
- The 16-inch barrel features .578x28 RH threading that accepts most .45 caliber suppressors directly. However, the fixed barrel shroud may require a spacer for some suppressor models with larger diameters—check clearance with your specific suppressor manufacturer before purchasing.
