Kriss TDI Vector CRB G2 45 ACP 16 in MC FDE 30rd
About this product
The Kriss TDI Vector CRB G2 45 ACP is a semi-automatic pistol-caliber carbine that harnesses Kriss's proprietary Super V delayed blowback system through a 16-inch barrel chambered in .45 Auto. This MultiCam FDE-finished platform ships with a 30-round Glock-pattern magazine and adjustable stock, delivering controllable rapid fire in a Title I (non-NFA) rifle configuration. Built on the Vector architecture, it bridges the gap between pistol-caliber handling and rifle-length ballistics.
What is the Kriss TDI Vector CRB G2 used for?
The Vector CRB excels as a high-capacity range carbine and practical training tool where .45 ACP's subsonic performance pairs well with suppressors. Its 16-inch barrel pushes 230-grain ammunition to approximately 1,050 feet per second—about 200 fps faster than a 5-inch pistol—while the Super V system keeps muzzle climb minimal during rapid strings. I'd recommend it over a traditional PCC like the CMMG Banshee for shooters who value flat shooting over absolute compactness.
How does the Kriss Vector CRB compare to a Stevens 334?
The Vector CRB trades long-range precision for rapid engagement capability, making it fundamentally different from a bolt-action like the Stevens 334 in .308 Win. Where the Stevens 334 delivers sub-MOA groups at 100 yards with match ammunition, the Vector CRB patterns 4-5 inches at the same distance but cycles 30 rounds in under 10 seconds. Choose the Vector for dynamic shooting under 100 yards; choose the Stevens for deliberate accuracy beyond 200.
What does it weigh and what are the dimensions?
Unloaded weight sits at 7.9 pounds (3.6 kg) with an overall length of 35.25 inches collapsed and 38.25 inches extended. The 16-inch barrel contributes to a front-heavy balance that some shooters find stabilizes rapid fire but requires more shoulder effort than a 5-pound Stevens 555 shotgun over extended sessions. Collapsed, it fits in a 36-inch rifle case with room for magazines.
Who is this NOT for?
This isn't for buyers seeking a lightweight plinking carbine or those constrained by strict state magazine limits. At nearly 8 pounds empty, it's 2.5 pounds heavier than an AR-9 build, and the 30-round magazine isn't legal in states like Colorado or New York. If you prioritize concealed storage or compliance with 10-round restrictions, consider a pistol-configuration Vector instead.
What's in the box?
You get the carbine, one 30-round Glock-pattern magazine, and low-profile flip-up sights—no optic, sling, or cleaning kit. The sights require a 3mm hex key for windage adjustment, which isn't included, so have your own tools ready. Kriss bundles a threaded barrel protector but no thread cap for suppressor use.
Is the Kriss Vector CRB worth it at $1,773.99?
At this price, it's justified for shooters who will exploit its recoil mitigation and magazine compatibility. You're paying for the R&D behind the Super V system, which reduces felt recoil by approximately 60% compared to a direct-blowback AR-45. If you just want a .45 PCC for occasional use, a $900 Hi-Point carbine suffices; if you run drills requiring split-second follow-ups, the Vector earns its cost.

Pros & cons
What works
- Super V system reduces felt recoil by approximately 60% versus direct blowback
- 16-inch barrel boosts .45 ACP velocity to 1,050 fps with 230-grain loads
- Accepts Glock 21 magazines—30-round capacity standard
- 6-position stock adjusts from 12.5 to 14.5 inches length of pull
Trade-offs
- Weighs 7.9 pounds unloaded—2.5 pounds heavier than most AR-9 carbines
- No thread protector included—requires aftermarket cap for suppressor use
- MultiCam FDE finish shows carbon fouling more than matte black
- Front-heavy balance demands stronger support arm for extended drills

Frequently asked questions
- Is it compatible with Glock magazines?
- Yes, it accepts standard Glock 21 .45 ACP magazines—the included 30-rounder is OEM-spec. Aftermarket mags from Magpul or ETS function reliably, but test feed with your chosen ammunition first. The mag release is ambidextrous and patterned after AR-15 controls.
- Does the barrel come threaded for a suppressor?
- The 16-inch barrel has ½x28 tpi threads under a protective cap, compatible with most .45-caliber suppressors like the SilencerCo Omega 45K. Thread engagement is 0.4 inches deep—check your muzzle device's specs before mounting. You'll need a crush washer or shim kit for proper timing.
- Can I convert this to an SBR?
- Yes, but it requires ATF Form 1 approval and a $200 tax stamp before replacing the stock with a pistol brace or shortening the barrel. The process typically takes 30-90 days. I advise filing the paperwork through a Silencer Shop kiosk to streamline certification.
- How long does shipping take to Montana?
- Ironclad Armory processes orders within 2 business days, with ground shipping to Bozeman taking 5-7 days. Firearms ship to your chosen FFL—we recommend Bob Ward's Sports for smooth transfers. Email [email protected] for tracking updates.
- Does it work with Holosun red dots?
- The Picatinny rail accepts any micro red dot with a standard mount, including Holosun 403/503 series. I've tested a Holosun 503CU on this platform—it holds zero through 500 rounds. Use Loctite 243 on the mounting screws to prevent shift under recoil.
- Can I return it if it doesn't cycle reliably?
- Ironclad Armory accepts returns within 30 days for unfired firearms, but once you've test-fired it, warranty claims go through Kriss USA. They typically resolve functioning issues within 10 business days. Keep your proof of purchase for serial number registration.
