Steyr Model 1911 Semiautomatic Trials Rifles
11m
In 1909, the Austro-Hungarian Empire announced a desire to find a new semiautomatic military rifle, and requested proposals from arms manufacturers. Six rifles were submitted to the resulting trials in 1911, including this model from Steyr chambered for the 7x57mm Mauser cartridge. It uses a two-lug rotating bolt and a short stroke annular gas piston system very similar to the German Gewehr 41 of three decades later. It also featured an unusual rotating dust cover, which was automatically opens and closed by the cycling bolt.
The trials resulted in no rifle being deemed suitable, and further development was interrupted by the First World War. In the after math of the testing, Steyr did release a civilian pattern version of the rifle in 6.5mm Mannlicher but did not garner significant sales. Total production is not known, but was very small.
