Kriss Usa Vector Sbr G3 45Acp 5.5 Alpine 30Rd

The Kriss USA Vector SBR in .45 ACP is a modern, innovative take on the submachine gun platform built for shooters who want genuine compact firepower without the complexity of traditional designs. At just 5.5 inches of barrel length and collapsing to 24.25 inches overall, this semi-automatic rifle delivers controllable recoil and pointability in tight spaces—whether you're working through home-defense scenarios, running tactical courses, or simply exploring what a purpose-built, short-barreled rifle can do. The Vector's legendary delayed-blowback operating system and Kriss's proprietary recoil mitigation make it pleasantly shootable despite the .45 ACP's natural stomp, and the Alpine finish pairs practical aesthetics with real durability.

Built for serious users, the Vector SBR G3 comes ready to work. The 4140 Chrome Moly barrel wears a hard Black Nitride QPQ finish that shrugs off corrosion and handling wear. The included 30-round magazine gives you substantial capacity, while the ambidextrous, telescopic folding stock adapts to your body and your tactical situation—collapse it for movement through vehicles or structures, extend it for precision work at the range. Thread the muzzle (.578x28 RH) and add suppressors, compensators, or flash hiders to refine the gun's behavior on target.

The single-stage pivoting trigger is clean and predictable, and the whole platform tips the scales at just 6.4 pounds, making this an easy gun to handle for extended sessions. This is serious hardware for experienced shooters who understand NFA rules and want a compact, semi-auto rifle that performs and looks the part.
