The Kriss Vector CRB (Carbine) is a semi-automatic pistol-caliber carbine developed by Kriss USA, a company known for its innovative firearms designs. The Vector CRB is based on the Kriss Vector platform, which was originally introduced in 2007. The Kriss Vector CRB is typically chambered in pistol calibers such as 9mm Parabellum, .40 S&W, or .45 ACP. The Kriss Vector features a unique operating system known as the "Kriss Super V System," designed to mitigate recoil and muzzle climb. This system redirects recoil energy downwards and away from the shooter, resulting in improved control and accuracy during rapid fire. The Kriss Vector has a distinctive, futuristic, and angular appearance. It incorporates a folding stock or brace, making it compact and easily transportable. The controls are ambidextrous, allowing for use by both left- and right-handed shooters. The Kriss Vector CRB typically uses proprietary Glock-style magazines. It often includes Picatinny accessory rails for mounting optics, lights, lasers, and other accessories. The Kriss Vector series is known for its innovative design, recoil reduction, and versatility. It's a popular choice among shooters looking for a reliable pistol-caliber carbine for a variety of purposes, including home defense, recreational shooting, and competition.
