The S12K Tactical or Saiga-12 is a Russian design derived from the Kalashnikov pattern rifles. The S12K Tactical has been modified with a collapsible stock, new pistol grip, AGP magazines, a new front rail, Magpul angled foregrip, an upturned bolt handle and an EO Tech sight. The S12K is semi automatic so it has high fire rate and accuracy but slightly lower accuracy compared to the JCS but the larger magazine size and box magazine give a good trade off.
