The KRISS USA Vector SBR Gen III delivers precision .45 ACP performance in a compact, ambidextrous platform built for sport shooting and recreational use.
Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed
The KRISS Vector SBR Gen III 45 ACP rifle combines innovative design with versatile firearm engineering. This semi-automatic platform fires the powerful .45 ACP cartridge from a 5.5″ threaded barrel. The Vector SBR handles both sport shooting and recreational use with exceptional control and reliability.
Furthermore, the Vector SBR Gen III features a 30-round magazine capacity, giving you extended shooting sessions without frequent reloads. Additionally, the threaded barrel accepts muzzle devices, allowing customization for sound suppression or muzzle management. The Cerakote finish in Arctic Delta provides both aesthetic appeal and durable protection against the elements.
Design and Ergonomics
Moreover, this rifle includes an ambidextrous safety mechanism, making it equally comfortable for left- and right-handed shooters. The adjustable folding stock accommodates different shooting positions and storage needs. Low-profile flip-up sights are integrated for quick target acquisition without optics.
The interchangeable pistol grip lets you customize your setup to match your shooting style. These features combine to create a platform that handles dynamic sport shooting environments effectively.
Performance and Versatility
In addition to its compact design, the KRISS Vector SBR Gen III excels at recreational shooting where shooters demand both accuracy and ergonomic efficiency. The .45 ACP caliber delivers consistent ballistics across various shooting distances. Therefore, whether at the range or in sport shooting competitions, the Vector SBR remains a dependable choice for serious shooters.
