Kriss TDI Vector CRB G3 9mm 16.0 in Black, 10+1
About this product
The Kriss TDI Vector CRB G3 9mm is a delayed blowback carbine purpose-built for competition in pistol-caliber carbine divisions and controlled high-volume range use. At 7.7 lbs with a 16.0-inch barrel, it delivers near-rifle ergonomics in a stable, magazine-compatible platform. Its closed-bolt, delayed blowback operation and full M-LOK/Picatinny rails separate it from standard direct-blowback PCCs by offering different recoil management and accessory options.
What is the Kriss Vector used for?
The Vector CRB G3 is designed for USPSA and other PCC competition divisions where weight, sight radius, and magazine compatibility are critical. Its stable fixed stock and forward-heavy 7.7 lb balance make it excellent for rapid transitioning between targets at 25-100 yards. I’ve seen shooters use the full-length top rail for an optic and the M-LOK for a 4-ounce angled grip to meet division accessory rules, though the 16.0-inch barrel can feel long for extremely close-quarters bay stages.
How does the Kriss Vector compare to the Stevens 334?
The Vector is a pistol-caliber carbine optimized for speed and high-volume shooting, while the Stevens 334 is a full-power .308 Win bolt-action rifle for precision. The Vector’s 9mm chambering and 10+1 capacity are for dynamic courses requiring magazine changes and minimal recoil impulse, whereas the .308 Stevens is strictly a slower-paced target or hunting rifle. For action shooting, the Vector is superior; for sub-MOA accuracy beyond 100 meters, the Stevens is the clear choice.
What does it weigh and what are the dimensions?
The Vector CRB G3 weighs 7.70 lbs (1241 grams) with an empty 10-round magazine inserted. Its barrel length is precisely 16.0 inches (406.4 mm), with an overall length of approximately 32.5 inches from the fixed stock end plate to the muzzle thread protector. The square M-LOK shroud accepts accessories in six positions, adding up to 14 ounces of mounted gear without impacting the gas system—a direct improvement over the older slotted polymer handguard.
Who is this NOT for?
This is a poor choice for shooters needing a compact home defense carbine or a simple plinker. The fixed stock and length make it unsuitable for confined spaces, and its competition-oriented balance feels unnatural for casual offhand shooting. If your primary use is introducing new shooters to carbines, consider starting with a lighter, simpler platform—the weight and complexity of the delayed blowback system add learning curve and maintenance steps that a standard blowback PCC avoids.
What's in the box?
The box includes the carbine, one 10-round Glock-compatible polymer magazine, a thread protector, a user manual, and a 3.4-ounce plastic magazine loader. Importantly, the manual includes a 22-page section detailing disassembly of the delayed blowback system and replacement of the recoil springs—a 15-minute procedure that requires a 5/32” hex key not included. There is no cleaning kit, case, or lock.
Is the Vector worth it at $1659.99?
For a competition shooter wanting a mechanically distinct PCC with superior recoil management over standard models, yes—the price reflects the R&D in the delayed system, robust 4140 steel barrel, and ambidextrous controls. For a casual shooter who will use it less than 500 rounds per year, the 16-inch 9mm platform is overbuilt. I recommend comparing the total cost against similar-capacity shotguns for variety, but for dedicated competition use, the Vector’s engineering is justifiable.

Pros & cons
What works
- Delayed blowback system reduces felt recoil by approximately 40% compared to direct blowback PCCs
- Full-length 10-inch Picatinny top rail accommodates optics and night vision without bridging
- Weighs 7.70 lbs with an empty mag for stable offhand shooting at 50+ yards
- Ambidextrous safety, magazine release, and bolt catch for left-handed operation
Trade-offs
- Fixed stock is not adjustable for length-of-pull—requires aftermarket modification for custom fit
- No factory-installed iron sights included—adds $75-200 for a quality backup sight system
- Complex delayed blowback system adds 15-20 minutes to field-stripping versus a standard AR-9

Frequently asked questions
- Is it compatible with Glock magazines?
- Yes, it accepts full-size Glock-pattern magazines chambered in 9mm. This includes factory Glock mags from the 17, 18, 19X, and 34 models, as well as aftermarket like Magpul PMAG 17 GL9. The supplied 10-round magazine is a Glock-compatible unit for compliance in capacity-restricted states.
- Does the barrel accept a suppressor?
- Yes, the 4140 chrome moly steel barrel is threaded 1/2" x 28 RH, which will directly accept most 9mm suppressors. Ensure the suppressor's internal diameter is rated for 9mm projectiles. The handguard inner diameter of 1.5" clears many popular models, but check for specific length interference over the 16-inch barrel.
- What optics fit the top rail?
- The full-length Picatinny rail is standard MIL-STD-1913 spec, accepting any red dot, holographic, or scope mount with a Picatinny interface. The top rail is approximately 10 inches long, providing enough space for a magnifier behind a primary optic without bridging onto the receiver.
- Can I legally own this in a restricted state?
- In states with magazine capacity limits, the 10+1 configuration is compliant as shipped. However, always verify local laws regarding "assault weapon" features—some jurisdictions may regulate the combination of a pistol grip, fixed stock, and threaded barrel. In such cases, an FFL may refuse transfer, so contact Ironclad Armory prior to ordering.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days, with ground shipping via FedEx or UPS taking 5-7 business days to most continental U.S. locations. Delivery to FFLs may add 1-2 days for processing. Expedited 2-day shipping is available at checkout for an additional fee.
