KRISS Vector CRB G3 16in .45 ACP Alpine 30rd
About this product
The KRISS Vector CRB G3 16in .45 ACP is a purpose-built, TITLE II compliant 16-inch pistol-caliber carbine that uses KRISS's patented delayed blowback system in a Gen 3 chassis to tame the .45 ACP round for competitive and training use. It's a factory-configured non-NFA firearm designed from the ground up to offer the Vector's signature recoil mitigation in a platform that can ship directly to your FFL without SBR paperwork. The Gen 3 CRB platform incorporates M-LOK compatibility, a telescopic folding stock, and Glock magazine commonality to create a modern, adaptable .45 ACP carbine out of the box.
What is the KRISS Vector CRB G3 used for?
This carbine is engineered for two primary roles: USPSA PCC division competition and high-round-count training sessions where shooter fatigue from recoil matters. The core KRISS Super V system redirects bolt energy downward, reducing muzzle climb by roughly 60% compared to a direct blowback AR-9 platform chambered in .45 ACP. For a practical shooter running 200-round practice sessions, this translates to faster, more accurate follow-up shots and significantly less shoulder fatigue, allowing focus to remain on technique, not recoil management.
How does the KRISS Vector compare to the CMMG Banshee 300 in .45 ACP?
The KRISS Vector's delayed blowback system is mechanically superior for pure recoil reduction, but the CMMG Banshee 300 is a more modular AR-pattern platform. The Vector's proprietary operating system results in a heavier, more front-heavy carbine weighing 7.7 lbs with an empty magazine, while a comparable CMMG Banshee 300 with an 8-inch barrel weighs approximately 5.8 lbs. The KRISS is the better choice for a shooter solely focused on minimizing felt recoil in competition; the CMMG is better for someone who already owns AR-15s and wants magazine, accessory, and manual-of-arms commonality in a lighter package. Both use Glock pattern magazines.
What does it weigh and what are the dimensions?
Unloaded weight is 7.7 lbs (3.49 kg), making it a substantial pistol-caliber carbine, largely due to its steel barrel shroud and internal operating mechanism. Collapsed overall length with the stock folded is a compact 25.25 inches (641 mm), which fits easily into the included 28-inch hard case. Fully extended, the overall length is 35.5 inches (902 mm), making it a standard-length carbine for handling. The 16-inch, 4140 chrome moly barrel has a 1:16 twist rate optimized for stabilizing heavy .45 ACP projectiles up to 230 grains.
Who is this NOT for?
This is a poor choice for a first-time firearm buyer or someone seeking a lightweight home defense carbine. The 7.7 lb weight and proprietary manual of arms—including a non-standard bolt release location and a stiff, short-throw safety—require dedicated practice to run efficiently under stress. It's also not ideal for hunters looking for a compact, lightweight bolt-action rifle like the Stevens 334; the Vector is a specialized tool for volume shooting, not precision field work.
What's in the box?
KRISS ships this carbine with exactly what's needed for immediate function and compliance, nothing more. You receive one 30-round Glock-pattern magazine, a basic cleaning kit solvent to rod, a cable lock meeting CA DOJ requirements, the operator's manual detailing takedown and maintenance of the Super V system, and a rigid plastic hard case measuring 28 x 10 x 3.5 inches. The case has foam cut specifically for the folded carbine and included accessories, providing adequate protection for transport to the range, though not for checked airline luggage.
Is the KRISS Vector CRB G3 worth it at $1609.99?
At this price point, the KRISS Vector justifies its cost only for the shooter who specifically values its unique recoil-mitigating mechanics over platform commonality. You are paying a premium for a niche operating system. For a shooter who wants a more traditional, lighter-weight pistol-caliber carbine for general plinking, a versatile over-under shotgun like the Stevens 555 Sporting at nearly half the price offers a completely different, but arguably broader, utility. The Vector's value is in its singular performance advantage in recoil management, making it worth the investment for competitive PCC shooters who need that edge.

Pros & cons
What works
- Super V delayed blowback system reduces felt recoil and muzzle climb by approximately 60% vs. direct blowback .45 carbines.
- Collapses to a compact 25.25 inches overall length with the stock folded for transport and storage.
- Includes one 30-round magazine, compatible with the ubiquitous Glock 21 platform for easy sourcing of spares.
Trade-offs
- Heavy 7.7 lb weight is noticeable, especially when held off-hand for extended periods during competition stages.
- Proprietary manual of arms requires practice; the bolt release is non-standard and stiff from the factory.
- Alpine (white) finish shows carbon fouling and handling marks more readily than a standard black finish.

Frequently asked questions
- Is it compatible with standard Glock .45 ACP magazines?
- Yes. It accepts any double-stack, full-size Glock-pattern magazine chambered for .45 ACP, including the Glock 21 13-round, Kriss 30-round, and aftermarket extensions. One Kriss 30-round magazine is included. The magazine release is ambidextrous and based on the Gen 3 Glock style.
- Does the threaded barrel accept a suppressor?
- Yes. The barrel is threaded .578x28 RH, which is the standard thread pitch for .45 caliber suppressors from manufacturers like SilencerCo and Dead Air. You must complete a Form 4 and wait for ATF approval before attaching a suppressor. The 16-inch barrel length keeps this configuration Title I compliant even with a muzzle device installed.
- How long does shipping take to my FFL?
- Ironclad Armory processes and ships in-stock firearms within 2 business days of FFL verification. Transit time via UPS or FedEx is typically 3-5 business days to the continental US. You will receive tracking information and must coordinate directly with your chosen FFL for pickup once the shipment arrives.
- Does the folding stock lock in place rigidly?
- Yes. The telescopic folding stock locks solidly into both the fully extended and fully folded positions via a positive detent mechanism. In the folded position, there is approximately 0.5mm of play, which is negligible and does not affect function. The six-position telescoping adjustment requires a firm pull to adjust but holds securely at each setting.
- Can the M-LOK shroud accept a vertical foregrip?
- Yes, but with a critical legal distinction. Installing a vertical foregrip on this 16-inch barrel rifle is legal. The Gen 3 square shroud has M-LOK slots at the 3, 6, and 9 o'clock positions. A 6 o'clock vertical grip is a common and functional addition. Installing the same grip on a pistol-configured Vector would create an AOW under the NFA.
