The VSS (translated \"Special Sniper Rifle\") also named Vintorez (Thread Cutter), is a suppressed sniper rifle manufactured by Tula Arms Plant. It is in use by various military and otherwise militant organizations, especially those of former Soviet states.The VSS Vintorez was designed from the start to be a suppressed, flashless sniper rifle. It uses a heavy subsonic 9x39 mm cartridge in combination with its integral sound suppressor. The heavy bullet is very effective at penetrating body armor even with its subsonic speed. Its effective range is 400 meters. The VSS is normally used in semi-automatic, but it is capable of automatic fire.Since the VSS is meant for use in discreet operations, it can be broken down into three parts to be carried in a special 450 x 370 x 140 mm (17.7 x 14.5 x 5.5 inch) briefcase. The briefcase also has space for a PSO-1 scope, a NSPU-3 night vision device, and two magazines.
