Steyr Model 1911 Semiautomatic Trials Rifles
This video explores the Steyr Model 1911 Semiautomatic Trials Rifle, one of six designs submitted to the Austro-Hungarian Empire in 1909. Chambered in 7x57mm Mauser, the rifle featured a two-lug rotating bolt and a short-stroke annular gas piston. Its unique rotating dust cover, operated by the bolt cycle, is highlighted. The trials concluded without selecting a rifle, and further development was halted by WWI. A civilian variant was later produced in 6.5mm Mannlicher but saw limited success. Production numbers are believed to be very small.
