The Steyr HS .50 is a single-shot, bolt action anti-materiel sniper rifle, chambered in .50 BMG. It has no built-in magazine. Each round has to be loaded directly into the ejection port and is pushed into the chamber by the bolt. The fluted barrel is cold hammer-forged and has an effective range of up to 1,500 m. It has an adjustable bipod, a muzzle device that reduces recoil significantly, and a Picatinny rail for the installation of various optics.

The original Steyr HS-50 was designed by Heinrich Fortmeier, on behalf of Steyr Arms. Unlicensed variants of the HS. 50 include the AM-50 Sayyad produced by Iran and the Golan S-01 produced by Syria. The HS .460 variant is chambered in .460 Steyr cartridge instead.
