Steyr CL II M

The History of Steyr

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 CL II M Rifle Review

Steyr introduced the CL II bolt-action rifle series in 2014. It succeeded the popular Mannlicher Classic rifle which had been on the market since 1997. It is equipped with Steyr's SBS (Safe Bolt System) which is based on a 2+1 safety, operated by a wheel switch. Additionally, there are four locking lugs and multiple gas ports on the bolt. The grooves on the bolt allow for a smooth operation, even in adverse environmental conditions.

The magazine holds 4 rounds, except for the magnum versions where the magazines have a 3-shot capacity. The action is of the push feed type. The non-magnum models’ barrel length is either 508 mm or 558 mm while the magnum CL II rifles’ barrel measures 600 mm or 635 mm, depending on the caliber. The Mannox® surface provides corrosion resistance, abrasion protection, and minimizes light reflection.
