The story of Steyr Mannlicher began in 1821 when Leopold Werndl, a blacksmith, started manufacturing iron parts for firearms in the city of Steyr. His son Josef Werndl took over his business and founded the 'Josef und Franz Werndl & Comp. Waffenfabrik und Sägemühle in Oberletten ' in 1864. In the following years, he played a crucial role in the development of several rifles, including the straight pull-rifles M. 85 and M. 86. At the beginning of the 20th century, the engineers Ferdinand Mannlicher and Otto Schönauer developed the Original Mannlicher Schönauer, a legendary hunting rifle, the production of which took place until 1973. The company grew over the years and reached a production capability of 4.000 firearms per day before World War I. After the War, Steyr was prohibited from firearm manufacturing after the Treaty of Saint-Germain-en-Laye was signed. To avoid going bankrupt, they used their knowledge and machinery to manufacture cars, bicycles, motorcycles, tractors, trucks, dynamos, electric motors, and other things (they were not allowed to resume firearm production until 1930). In 1926, the company’s name was changed to Steyr-Werke AG. It merged with Austro-Daimler-Puchwerke AG in 1934 to form Steyr-Daimler-Puch AG. Both Austro-Daimler (previously a subsidiary of Daimler-Motoren-Gesellschaft) and Puch (founded by the Slovenian inventor and mechanic Janez Puh) were active in the automobile industry, with Puch also manufacturing bicycles, motorcycles, and mopeds.
They even employed Ferdinand Porsche for a time – he made several contributions to the company – one of them was designing an air-cooled 3.5 L V8 engine for the Steyr RSO Raupenschlepper Ost tracked vehicle. Steyr is known for modifying Fiat cars and adding their engines to some of the models (Steyr-Fiat 1100 Mod E and Fiat 1400, for example). In 1972, they cooperated with Mercedes in the design of Puch G, also known as Mercedes Benz G-class.
During World War II, the company focused on firearm, vehicle, aviation engine, and ball-bearing production for the German military. After a short firearm manufacturing ban after the end of the War, Steyr resumed the production of arms in 1950. In the years that followed, they presented many innovative firearms such as StG 77 (also known as Steyr AUG), an assault rifle with a bullpup design; SSG 69, which was ahead of its time after its release in 1969, and many others. In 1989, Steyr-Daimler-Puch AG broke up into different sectors; Steyr Mannlicher AG became independent. The company has strived to be internationally oriented, so it changed its name to Steyr Arms in 2019.
Steyr Duett is an over-and-under combination rifle with a free-floated barrel presented by Steyr Mannlicher around 2014. The rifle is equipped with an automatic decoking device that is activated when the rifle is opened. This is done by turning the lever on the rear on of the rear end of the receiver to the right. The cocking slide is positioned on the rear end of the receiver on the action tang and must be pushed forward to fully cock the rifle until a locking pin engages into the slide and a red dot indicator is visible. Pressing and pushing the locking pin on the cocking lever moves the slide to the rearmost position, which allows for safely loading and unloading the rifle.
Each barrel on the rifle has a dedicated trigger mechanism. The rifle comes with an optional forward set function at the first trigger and a direct trigger at the second trigger. The front trigger operates the lower rifled barrel, and the back trigger controls the upper barrel which is suitable for shotgun gauges. Steyr Mannlicher Duett can be disassembled in a few simple steps for maintenance purposes. The sights are pre-installed, with the front sight being adjustable for elevation and the rear one for windage.
Steyr Mannlicher Duett is available in the barrel length of 600 mm (24-inch).
