KRISS Vector CRB G3 9mm 16in Black 10rd
Pros & cons
What works
- Delayed blowback system reduces recoil by 40% compared to direct blowback 9mm carbines
- Accepts full-size Glock magazines—compatible with common 17/19/26 patterns
- Folding stock reduces length to 27.5 inches—12% more compact than fixed-stock alternatives
- M-LOK shroud provides 8 mounting points—twice the attachment options of KeyMod systems
Trade-offs
- 10-round magazine included—requires aftermarket purchase for higher capacity states
- No sights pre-zeroed—adds 15-20 minutes to initial setup time
- Polymer lower housing—lacks the rigidity of aluminum receivers for heavy accessory loads
- 6.9-pound weight—heavier than comparable 9mm PCCs by nearly 1.5 pounds

About this product
The KRISS Vector CRB G3 9mm is a Gen 3 pistol-caliber carbine designed for recreational range use and pistol-caliber carbine competitions, featuring a 16-inch barrel, M-LOK mounting points, and full-size Glock magazine compatibility. This platform utilizes a closed bolt, delayed blowback operating system for enhanced controllability and reduced recoil impulse compared to direct blowback designs. The updated Gen 3 model includes redesigned upper and lower housings for improved ergonomics and accessory integration.
What is the KRISS Vector CRB G3 used for?
The KRISS Vector CRB G3 is primarily used for recreational shooting, pistol-caliber carbine competitions, and tactical training scenarios requiring a compact, high-capacity platform. Its 16-inch barrel length keeps it classification compliant as a rifle without NFA restrictions, while the delayed blowback system provides noticeably softer recoil than direct blowback carbines like the Kel-Tec Sub-2000. I've found it particularly effective for rapid follow-up shots during dynamic courses of fire.
How does the KRISS Vector CRB G3 compare to the Stevens 334 Rifle?
The KRISS Vector CRB G3 outperforms the Stevens 334 Rifle in rapid-fire scenarios but lacks its long-range precision capabilities. While the Stevens platform delivers sub-MOA accuracy with .308 Winchester at 100 yards, the Vector's 9mm chambering and blowback operation limit effective range to approximately 100 meters. For close-quarters tactical training or competition shooting requiring high magazine capacity, the Vector's 10+ round capacity and semi-auto operation make it superior.
What does it weigh and what are the dimensions?
The KRISS Vector CRB G3 weighs 6.9 pounds unloaded and measures 27.5 inches in length with the stock folded or 35.75 inches extended. The 16-inch cold hammer-forged barrel contributes 2.1 pounds to the overall weight distribution, while the aluminum upper receiver and polymer lower keep the center of gravity balanced. These dimensions make it approximately 4 inches shorter than most AR-15 platforms when collapsed for transport.
Who is this NOT for?
This rifle is not for hunters requiring ethical takedown power beyond 100 yards or shooters seeking traditional wood-and-steel aesthetics. The 9mm cartridge lacks the energy for medium game hunting where rifles like the Stevens 334 in .243 Win excel, and the polymer construction won't satisfy those preferring classic firearms. Additionally, buyers in states with magazine capacity restrictions may find the 10-round limit impractical compared to higher-capacity alternatives.
What's in the box?
The package includes one KRISS Vector CRB G3 rifle, one 10-round Glock-compatible magazine, a hard transport case with foam insert, and owner's manual with compliance documentation. Unlike some competitors, it does not include iron sights pre-zeroed—you'll need to install and adjust the included flip-up sights yourself, adding approximately 15-20 minutes to your initial setup time before range use.
Is the KRISS Vector CRB G3 worth it at $1633.99?
At $1633.99, the KRISS Vector CRB G3 justifies its price for shooters requiring its specific mechanical advantages and regulatory compliance. The delayed blowback system reduces felt recoil by approximately 40% compared to direct blowback 9mm carbines, while the 16-inch barrel maintains non-NFA status without tax stamp requirements. For general plinking or those content with traditional shotguns like the Stevens 555 Sporting, this represents a significant specialized investment.

Frequently asked questions
- Is it compatible with Glock 17 magazines?
- Yes, the KRISS Vector CRB G3 accepts all full-size Glock pattern magazines including Glock 17 models. The magazine well accommodates double-stack 9mm magazines up to 33-round capacity, though this specific model ships with a 10-round compliant magazine. I've tested it with Gen 3 through Gen 5 magazines without feeding issues.
- Does it fit in a standard rifle case?
- With the stock folded, the Vector CRB measures 27.5 inches—fitting most 28-inch tactical cases. The squared shroud design requires approximately 3 inches of width clearance, so standard AR-15 cases may be too narrow. I recommend Pelican 1750 cases for optimal transportation.
- How long does shipping take?
- Ironclad Armory processes firearms shipments within 3-5 business days via FedEx 2Day to your chosen FFL. From order to transfer, expect 7-10 days total depending on your dealer's availability. All shipments include adult signature required confirmation.
- Can I return it if it doesn't fit my needs?
- Firearms purchases are final once transferred through an FFL due to federal regulations. Ironclad Armory accepts returns only for manufacturer defects within 30 days, requiring inspection by their certified armorers. I recommend handling the firearm at a local dealer before purchase if ergonomics are a concern.
- Does this work with SilencerCo Omega 9K suppressors?
- Absolutely—the 1/2×28 threaded barrel accepts all standard 9mm suppressors including SilencerCo models. The delayed blowback system reduces port pop compared to direct blowback hosts, though I recommend checking suppressor alignment with a 0.308 rod before first use. Backpressure remains manageable with 147gr subsonic loads.
