The Kalashnikov USA™ KS-12 shotgun is a semi-automatic shotgun made here in the U.S.A. and based on the Russian Saiga series. The KS-12 accepts 2.75” and 3” shells from low brass to slugs thanks to our innovative adjustable gas system. The shotgun also comes equipped with the classic AK style side-mounted optics rail. The threaded barrel on our KS-12 means you can install any muzzle break of your choice that fits. The KS-12 ships with one 5-round magazine. Larger magazines and drums are also available. Most currently available Saiga accessories will also work on the KS-12 including magazines, drums, muzzle devices and chokes.
