The SIG Sauer 200 STR (Scandinavian Target Rifle), also known as the SIG Sauer 200 STR Match, is a bolt-action rifle mostly used as a target/competition rifle for national competitions by Norwegian, Swedish and Danish sport shooters. It is a variant of the Sauer 200 TR or SIG Sauer 200 TR Match rifle that features thicker diameter barrels. The 200 STR is produced by J. P. Sauer & Sohn GmbH in Germany. The Sauer 200 STR rifle has a factory warranty of 15 years, exempting the use of overpressure (handloaded) ammunition—the 6.5×55mm Pmax piezo pressure is set at 380 MPa (55,114 psi) and the .308 Winchester/7.62×51mm NATO Pmax piezo pressure is set at 415 MPa (60,191 psi) by Sauer & Sohn following the relevant C.I.P. rulings. Design details Due to the Sauer 200 STR modular design, barrel, chambering, and trigger groups can be relatively easy changed by the user with the help of simple tools. The rifle stocks are however factory fitted to a particular rifle, so stocks can not be easily exchanged between rifles. Also available are .22 Long Rifle conversion kits and genuine left-hand versions for all chamberings. Bolt action The Sauer 200 STR is a bolt action sport rifle based on the Sauer 200 receiver introduced in 1985. This receiver is CNC machined out of a single piece of steel and has been designed for maximum stability and is also used in several other Sauer rifle variants like the SIG-Sauer SSG 3000 and, slightly modified, in the 21st century Sauer 202. Tight manufacturing tolerances, a high quality surface finish and non protruding locking lugs are the basis for "smooth" bolt action manipulation. The bolt has six lugs that lock directly into the barrel. This construction prevents that bolt thrust forces act directly to the receiver that encloses the cartridge with a radial collar that, in conjunction with a gas relief hole intended for pressure relieve during catastrophic ammunition failures, contributes to strength and safety. Further the rifle features a relatively lightweight firing pin resulting in a lock time of 2.4 milliseconds . The bolt knob uses M6 threads, enabling the use of aftermarket bolt knobs. Barrel The 200 STR chromium molybdenum (CrMo) steel hammer forged match barrels have a end diameter. Trigger The 200 STR has a two-stage trigger mechanism with an adjustable trigger pull of approximately . The trigger can also be adjusted for length, horizontal
