The Saiga-12 is a shotgun available in a wide range of configurations, patterned after the Kalashnikov series of rifles and named after the Saiga antelope native to Russia. Like the Kalashnikov rifle variants, it is a rotating bolt, long-stroke gas piston operated firearm that feeds from a square magazine. All Saiga-12 configurations are recognizable as Kalashnikov-pattern guns by the large lever-safety on the right side of the receiver, the optic mounting rail on the left side of the receiver and the large top-mounted dust cover held in place by the rear of the recoil spring assembly. Saiga firearms are meant for civilian domestic sale in Russia, and export to international markets.

The Saiga semi-automatic rifles are a family of Russian semi-automatic rifles manufactured by Kalashnikov Concern, which also manufactures the original AK-47 and its variants, Saiga-12 shotguns and Dragunov sniper rifle. Saiga rifles are a sport version of the Kalashnikov rifle, and are marketed for hunting and civilian use. They are sometimes referred to as Saiga Sporters.
