Steyr Mannlicher THB

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 THB Rifle Review 

Steyr THB which stands for ‘heavy tactical barrel’ is a push-feed bolt action rifle with a polymer stock that is based on Steyr’s Pro Hunter series. The rifle uses the renowned SBS (Safe Bolt System) wheel switch is used for safety. This system is predominantly used on all newer Steyr rifles due to its reliability. 

The safety is put into the loading position by turning the safety wheel rearwards until a click is heard. When the rearmost position is reached, the protruding grey catch is visible - in this position, the trigger is locked, and the bolt cannot be opened. Inside the steel action is a bolt with four opposed locking lugs. On the top of the receiver, there is a Picatinny rail pre-mounted and ready to be used for a simple installation of optic mounts. 

The two-stage direct trigger used on the THB is adjustable for weight and length of pull by turning the two screws positioned on the inner upper side of the trigger. An adjustable cheek pad is available optionally on the McMillan variant manufactured for the American market. The rifle comes with the same two-stage, a four-round magazine with a double stack loading system that is used on a Pro Hunter. It is held in place by two catches positioned on each side. The EU version is only available in 6.5 Creedmoor whereas the models manufactured for the US market come in a .308 Winchester caliber as well. 

Steyr THB is available in the following barrel lengths: 406 mm (16-inch), 508 mm (20-inch), 635 mm (25-inch) and 660 mm (26-inch)

*The European version of THB is only available in a 635 mm (25-inch) configuration.

Introduction

The elevation is the vertical adjustment plane and its settings are usually done just by the adjustments on the scope (via elevation turret). The other option to adjust elevation is using an adjustable inclination scope mounts.

Their main purpose is the ability to shoot at long ranges. Scope mounts that offer adjustable inclination are normally the tactical ones from the highest price class.

The second most known solution of scope mounts with adjustable inclination is the one for air rifles. This is in general also a more affordable solution for mounts that fit on 11 mm dovetails.

We should not forget scope mounts with an adjustable inclination for hunting rifles. However, these are very rare.

Adjustable inclination scope mounts can be either

  • complete mounts or

  • just rail adapters.

Most of adjustable inclination scope mounts work on a principle of pivoting the entire mount around one horizontal axis, while the other connecting point defines the height/position. 

Adjustable Inclination Mounts

Tactical adjustable mounts

All of the tactical adjustable mounts with adjustable inclination are made from a single piece so that the scope tube cannot get flexed. These mounts are also very rigid and robust, which is an important advantage over the rest of the alternatives.

ERA-TAC mounts are probably the most famous and well-known scope mounts of this kind at this moment. It is important to mention that adjustments are not continuous.

ERA-TAC mounts have levels (pre-set) from 0 to 70 MOA. Setting these levels can be done by untightening the screw on the rear end of the mount first, then setting the level of inclination and tightening the same screw back. Between untightening and tightening the screw, the mount is not fixed and it is not possible to shoot with it. Increments done by clicks usually have numbers written so that users can always see where he left his settings and can remember settings.

These mounts are available for rifle scopes with scope tube dimensions

Another solution of adjustable inclination scope mounts is a rail solution that works similarly and is made by the company Cold Shot. However, Cold Shot offers more continuous settings. It is somewhat strange and interesting that Cold Shot mount has Picatinny rail above the mount as well as under the mount. Of course, this solution adds some height to the entire setup.

Air Rifle adjustable scope mounts 

Air rifle scope mounts with adjustable inclination are normally made for 1 inch (25,4 mm) and 30 mm scope tubes. They are less rugged and are not suitable for rifles with strong recoil. Although, they are quite affordable and easy to set up. Usually, they are used for compensation of bad mounting platforms.

On the market, it is possible to air rifle scope mounts with adjustable inclination also as separate rings (two piece scope mounts). Such mounts can damage (usually flex) the scope and this is why they are not as appropriate as one-piece mounts. A prime example of this type is Hawke’s two piece adjustable scope mount.

Adjustable scope mounts for hunting rifles

Adjustable scope mounts for hunting rifles are a rarity. Probably the main reason why this is so, is its questionable purpose. Hunting rifles are usually not used for long-range and therefore there is no need for scope mounts of this type.

The example: Dentler scope mounts offer inclination adjustability, but it is meant for zeroing your scope, not for long-range shooting.

Conclusion

Adjustable inclination scope mounts are designed for a specific purpose – extreme long-range shooting.

They all have in common high price, which seems logical, because of the high precision needed during manufacturing, extremely tight tolerances, and similar. 

Adjustable Inclination Mounts

On the market can be found two types of this solution:

  • either complete mounts like ERA-TAC mounts or

  • adjustable inclination rails like Cold Shot.

There can also be found air rifle mounts with elevation settings, however, we do not recommend them.
