KRISS VCTR SBR G3 9MM 5.5″ 40RD ALP
$1,758.39
The KRISS VCTR SBR G3 9MM 5.5″ 40RD ALP delivers the revolutionary Super V recoil mitigation in a compact NFA package, accepting Glock magazines and aftermarket AR grips. Ideal for collectors and shooters who demand low recoil and fast handling from a 9mm SBR.
The KRISS VCTR SBR G3 9MM 5.5″ 40RD ALP represents the most compact rifle configuration in the Vector lineage, a direct evolution of the iconic Super V system that has defined American subgun design since 2006. This Gen 3 Short Barreled Rifle, chambered in 9mm with a 5.5-inch barrel, delivers the same radical recoil mitigation and closed-bolt accuracy that made the original Vector a legend among shooters, but in a package that demands a tax stamp and rewards the shooter with unmatched handling.

Key Features
- Gen 3 Upper Housing Redesign: Accepts standard AR-15 pattern pistol grips, expanding customization options for shooters who prefer specific grip angles or storage compartments.
- Super V Recoil Mitigation System: The patented bolt carrier redirects recoil energy downward rather than rearward, reducing muzzle rise by up to 60% compared to conventional blowback designs—critical for rapid follow-up shots on multiple targets.
- Adjustable Side-Folding Stock: Six-position length-of-pull adjustment allows shooters to tailor the stock to body armor, shooting position, or personal preference while maintaining a compact 18.5-inch folded length.
- Integrated Picatinny Optics Rail: Continuous top rail accepts any red dot, holographic, or magnified optic without adapter plates, maintaining zero through the system’s unique reciprocating bolt motion.
- Ambidextrous Controls: Magazine release, bolt catch, and safety selector are fully reversible for left-handed shooters, a hallmark of KRISS design philosophy.
Who It’s For
This SBR is tailored for the collector who values mechanical ingenuity and historical significance—the Super V system is one of the few genuinely novel firearm operating mechanisms developed in the 21st century. It also suits the practical shooter who wants a compact 9mm carbine for home defense, competition, or range use where every inch of barrel reduction matters. The 40-round ALP magazine makes it a natural fit for those who train for high-round-count drills without constant reloading.
Pros and Cons
- Pro: The Super V system dramatically reduces felt recoil and muzzle climb, allowing shooters to keep sights on target through a full magazine dump—a capability unmatched by any other 9mm SBR under $2,000.
- Pro: Accepts standard Glock 17/19 magazines, leveraging the most common pistol magazine platform in the United States for logistical simplicity.
- Con: The reciprocating bolt carrier moves forward and back along the top rail, which can interfere with certain low-profile optics or require specific mounting solutions—a known quirk of the platform since its 2009 introduction.

Frequently Asked Questions
Does this KRISS Vector Gen 3 SBR require a tax stamp?
Yes. The 5.5-inch barrel and folding stock classify this as a Short Barreled Rifle under the National Firearms Act. You must file a Form 1 or purchase from an FFL/SOT who transfers it on a Form 4. We comply with all NFA requirements and provide the necessary paperwork.
Can I use standard Glock 17 magazines in the KRISS VCTR SBR G3?
Absolutely. The Gen 3 lower accepts all Glock 9mm magazines—G17, G19, G33, and the included 40-round ALP. No modifications or adapters are required.
What optics are compatible with the KRISS Vector Gen 3 SBR?
Any optic with a standard Picatinny mount fits the top rail. However, because the bolt carrier reciprocates along the rail, we recommend using a riser mount (1.5 inches or higher) to avoid interference. Brands like Aimpoint, Trijicon, and Holosun all work with appropriate mounts.
Does the Gen 3 accept aftermarket triggers?
Yes. The Gen 3 upper housing has been redesigned to accept standard AR-15 mil-spec trigger groups. Drop-in triggers from Timney or Geissele are compatible, though we recommend testing for function with the Super V system.
What is the effective range of the 5.5-inch barrel in 9mm?
With quality 124-grain FMJ ammunition, you can expect reliable accuracy out to 100 yards. Velocity loss from the short barrel is approximately 100-150 fps compared to a 16-inch barrel, but the Super V system maintains consistency for defensive engagements inside 75 yards.
