Siyavash (or "Siavash") Sniper Weapon System (SWS) is a relatively new Iranian-made sniper rifle debuted in 2013. It appears as a wholly conventional sniper rifle complete with full-length stock incorporating the forend, pistol grip and shoulder support. The shoulder is padded and the trigger underslung. The barrel is seated in the stock and exposed for most of its length. A bipod arrangement is typically affixed to the extreme end of the forend to provide for the needed forward support when firing the weapon. Optics are seated over the receiver in the usual way and provide precision fire at range.
Reports say that the Siyavash is an Iranian interpretation / clone of the classic American Remington M40 (detailed elsewhere on this site) which makes its action a traditional manually-operated bolt-lever handle. This would also provide for some performance assumptions including an effective firing range out to 800 meters. Its carry weight is reported to be about 14lb. Chambering would therefore be the NATO 7.62x51mm rifle cartridge fed by way of a five-round magazine (most likely detachable).
While the Siyavash doesn't break any new ground as sniper rifles go, it provides the Iranian Army with a viable, home-grown sniper weapon solution based upon a proven, established system. The American M40 has been in circulation since the mid-1960s and has seen considerable combat service ranging from the Vietnam War (1955-1975) into the current unrest in Afghanistan and Iraq.
The Siyavash SWS is seeing limited series production as of this writing (2015).
