Where Are Kahles Riflescopes Made?


Kahles is an Austrian manufacturer of high-quality sports optics, which includes riflescopes, binoculars, red dot sights, and range-finding devices. Established in 1898, Kahles is one of the oldest Europe-based optics brands, and therefore, carries a long heritage of manufacturing world-class sports optics for the European and North American markets. The company headquarters and its main production facility are located in Vienna, Austria where it was originally founded. Kahles was acquired by Swarovski Optik, the sports optics division of the Swarovski group in 1974.

Brief History

Named after its founder, Karl Robert Kahles, the company was established as a merger between two optics manufacturers based in Vienna, Austria. The parent organizations namely, Simon Plossl Company and Karl Fritsch’s workshop had been the makers of traditional microscopes and telescopes until the merger. Kahles acknowledged the potential of these small-time manufacturers and transformed the two businesses into a manufacturer of high-end binoculars and telescopes for astronomical purposes in 1898.

The First Kahles Riflescope

Recognizing the need for sports optics, Kahles unveiled telescopic sight for hunting rifles, called Telorar in 1900. The hunting scope was offered in five different optical configurations and it gained popularity among hunters within no time. Seeing the success of its first scope, Kahles invested considerable effort and funds into its development over the years. Since the introduction of TELORAR, the company has patented several riflescope features that have continued to be part of modern hunting riflescopes even today.

In addition to hunting scopes, Kahles also offered binoculars, astronomical telescopes, and optical sighting devices for marine professionals during this period. Unveiled in 1908, the revolutionary MIGNON riflescope became a landmark for the Kahles brand, as it was the first riflescope to be sold globally by an Austrian sports optics brand. In 1926, the popular Helia-series riflescope was launched with a relatively higher magnification along with an exceptionally large field of view compared to previous models. In the coming years, Helia became the signature riflescope brand of Kahles.

World War II and the Aftermath

Like many German factories, some Austria-based manufacturers were tasked with the production of military-grade products for the unified armed forces of Germany during World War II. Similarly, Kahles was forced to produce military-grade riflescopes, binoculars, and other optical components. During the length of the war, the business suffered substantial damage and unimaginable losses. In the aftermath of the war, Friedrich Kahles III, the grandson of the founder, carried out major restructuring to get the company back on its feet.

Thanks to the efforts of Friedrich Kahles, the company regained its standing within no time. In 1949, the Helia-series riflescope with variable magnification was unveiled for the first time. The development of the first waterproof riflescopes is also attributed to the Kahles brand. Unveiled in 1960, the engineers used O-rings to seal the optical cavity of the Helia Super riflescope, which helped to prevent external water from contaminating the optical cavity. In 1972, Kahles launched a new version of the Helia hunting scope with proprietary Kahles-AMV multi-coating. The innovative optical coating ensured more than 90% light transmission, which has since become the benchmark for all riflescopes and telescopic sights to this day.

An Addition Into the Swarovski Group

The riflescope business took the company to new heights under Friedrich Kahles III, and year after year, Kahles came to be known as the pioneer of hunting riflescopes around the world. The Swarovski Group showed interest in the company and subsequently acquired Kahles in 1974. The riflescope division of Swarovski Optik was still in the developmental stage, but with the heritage and experience of Kahles, the riflescope business started to thrive in incredible ways. In the following years, Swarovski Optik incorporated several innovative features into hunting scopes, such as reticle illumination, laser rangefinder, and up to 8x optical zoom.

Although Kahles has kept its brand separate, it is still managed by Swarovski Optik. Both brands offer a similar level of optical performance and built quality. Even after the acquisition, Kahles has continued to innovate its products with exciting features, such as automatic-light and Multi-zero adjustment.

Production Facilities

The main production facility has remained in Vienna, Austria ever since the company was established. Kahles maintains close relations with the management of Swarovski Optik, and a constant exchange of information and experience is the reason behind the success of the two brands.

Guntramsdorf, Lower Austria, Austria

In 2012, the company unveiled a new manufacturing facility in the town of Guntramsdorf in the state of Lower Austria, and it was designed with a lot of consideration towards environment-friendly factors. The new factory focuses on the production of riflescopes. All Kahles binoculars (Helia S is an exception and is made in Austria), red dots and rangefinder are outsourced from Asia.

The factory in Guntramsdorf is equipped with state-of-the-art technology for the manufacturing of high-end devices. The production floor houses CNC milling and lathe equipment that machine all metallic components from high-quality solid metal blocks. The glass components are for all products are acquired from Swarovski Optik, which helps in streamlining the production. The atmosphere and temperature in the assembly area are controlled, which prevents unwanted particles from entering the insides of the scope assembly.

After assembly, the scopes are purged with pressurized Nitrogen gas to prevent contamination from water vapour and dirt particles. All products go through strict quality control inspections to identify defective components and conforming scopes are sent towards the packaging area.

Originating in Austria, Kahles is a renowned brand of sports optics that is popular for producing high-quality riflescopes and binoculars for hunting, tactical and outdoor shooting competitions throughout the world. The company was established in 1898 following a merger of two optics manufacturers of telescopes and microscopes. As a result, Kahles has maintained a long heritage in the world of optics technology, which is one of the reasons behind the success of the brand.

Kahles was acquired by Swarovski Optik in 1974, and since then it has been managed inside the Swarovski Group as a subsidiary. The acquisition was aimed to develop Swarovski’s riflescope program by benefitting from the versatile experience and knowledge of Kahles’ riflescope division.

The company currently offers a series of sports optics products, such as riflescopes, binoculars, rangefinders, and red dot sights. While the manufacturing of binoculars has been outsourced to China and Japan, the rifle scopes are completely designed, manufactured, and assembled in-house in the Guntramsdorf factory near Vienna, Austria. Ever since the company was acquired by Swarovski, Kahles has nearly doubled the types of riflescopes it offers.

As of 2021, Kahles riflescopes are available for all types of outdoor activities in all price categories, which has enabled enthusiasts from all walks of life to enjoy the quality and performance of “Made in Austria” products.
