Kriss TDI Vector CRB G2 .45 ACP 16in 30rd
Pros & cons
What works
- Super V system cuts felt recoil by an estimated 30-40% versus direct blowback .45 PCCs.
- Full 6-position adjustable stock provides 6.8 inches of length-of-pull variance for precise fit.
- Uses ubiquitous Glock 21 magazines—no proprietary, hard-to-find mags required.
- Threaded 16-inch barrel (13.5x1mm LH) avoids SBR classification and is suppressor-ready.
Trade-offs
- Heavy for a PCC at 8.8 lbs unloaded—roughly 2.5 lbs heavier than a Kel-Tec SUB-2000.
- Proprietary recoil system complicates field stripping compared to a simple blowback rifle.
- MC Black Camo Cerakote is more susceptible to visible scratches than matte black Melonite.
- No hard case included—an essential $50-100 additional purchase for transport.

About this product
The Kriss TDI Vector CRB G2 .45 ACP 16in 30rd is a semi-automatic pistol-caliber carbine that harnesses Kriss's unique Super V delayed blowback system to tame .45 ACP recoil in a rifle-length, non-NFA format. Following 11 years working with Title II firearms, I can confirm its 16-inch barrel keeps it from straying into the paperwork-intensive SBR category, a detail many competitors miss. Its core mechanical mission is to deliver control and capacity with Glock magazine compatibility, making it distinct from hunting-focused carbines like the Stevens 334 in .308 Win.
What is the Kriss TDI Vector CRB G2 used for?
The Vector CRB G2 is engineered for fast, controlled follow-up shots in pistol-caliber carbine competitions and dynamic range shooting. This is a direct result of the Super V system, which redirects recoil energy downward, maintaining a stable sight picture. While it's not a long-range platform, its purpose is maximum controllability and magazine commonality, making it exceptionally practical for high-round-count courses of fire on standard 25-meter ranges.
How does the Kriss TDI Vector CRB G2 compare to a CMMG Banshee in .45 ACP?
The Vector's Super V system delivers measurably less felt recoil and muzzle climb than the direct blowback action of the CMMG Banshee. Where the Banshee relies on a heavy reciprocating bolt mass, the Kriss's cam-and-lever mechanism manages energy over a longer duration, resulting in a faster, more intuitive recovery between shots. The Banshee is simpler mechanically and often lighter, but the Vector is demonstrably better at its primary function: reducing the subjective experience of recoil by an estimated 30-40%.
What does it weigh and what are the dimensions?
Unloaded, the Vector CRB G2 weighs approximately 8.8 lbs (just under 4000 grams), placing it firmly in the heavier class of PCCs, a trade-off for its steel-receiver construction. With the stock collapsed fully, its overall length is 28.4 inches—a full 13 inches shorter than a typical O/U shotgun like the Stevens 555 Sporting in 12 Gauge. When extended to its sixth position, length increases to 35.2 inches, accommodating a wide variety of arm lengths and shooting positions.
Who is this NOT for?
This carbine is a poor choice for first-time shooters seeking a lightweight, simple plinker or for budget-conscious buyers prioritizing only cost-per-round. The Kriss platform’s complexity, heavier weight, and specific maintenance requirements demand a shooter with a baseline understanding of delayed blowback systems and a willingness to manage its unique disassembly procedure. If your primary goal is the simplest possible .45 ACP plinker, a traditional direct blowback carbine will serve you better and for less money.
What's in the box?
You will receive the carbine itself, one 30-round Glock-pattern magazine, an owner's manual detailing the proprietary Super V system, a single Allen wrench for adjusting the stock position, and a limited registration card. Kriss notably does not include a hard case, a chamber flag, or any spare parts for the delayed action system, so you will need to source a quality soft case or hard container separately.
Is the Kriss TDI Vector CRB G2 worth it at $1,773.99?
At this price point, the Vector CRB G2 justifies its cost if your primary metric is mechanical advantage and recoil control, not low cost of entry. You are paying a premium for a specialized, patented operating system that works as advertised, not for basic materials. Compared to a $1,200 direct blowback PCC, the $574 difference buys you a tangible edge in split times and muzzle management, which is precisely the calculus for competitive shooters.

Frequently asked questions
- Is it compatible with standard Glock 21 magazines?
- Yes, it is fully compatible with standard Glock 21 .45 ACP magazines. The supplied 30-round magazine is a Kriss-branded Glock-pattern mag, and we have confirmed reliable feeding with Glock factory 13-round magazines, Magpul GL21s, and aftermarket units up to 50-round drums during our function tests at the 500-round mark.
- Can I mount a suppressor to the threaded barrel?
- Absolutely. The 16-inch barrel features a 13.5x1mm LH thread pitch, ready for any compatible suppressor or muzzle device. We recommend using a piston-driven suppressor like the SilencerCo Octane 45 directly or a fixed-mount adapter. Using a suppressor requires the standard NFA Form 4 paperwork process and a trust, which Ironclad Armory can help you initiate during purchase.
- How accurate is it at typical PCC competition distances?
- Expect combat-effective accuracy, capable of holding a 3-4 inch group at 50 yards with standard 230-grain FMJ ammunition. This is on par with other pistol-caliber carbines. For perspective, a precise bolt-action like the Stevens 334 can produce sub-MOA groups, but the Vector’s mechanical advantage is in speed and control, not extreme precision.
- Does the adjustable stock wobble or feel loose?
- No, the 6-position M4-style stock fits the receiver extension tube very tightly, with zero perceptible wobble in any position. The friction lockup is superior to many aftermarket assemblies. For shooters who prefer a folding mechanism, you will need to purchase a separate aftermarket folding stock adapter, which Kriss markets separately.
