HS.50

The Steyr HS .50 is a .50 BMG single-shot anti-materiel rifle manufactured by Austrian firearms manufacturer Steyr Mannlicher. The rifle has been widely exported; in addition, Iran produces an unlicensed copy under the name AM-50 Sayyad, while Syria began producing a second unlicensed copy, dubbed the Golan S-01, in 2019. The Steyr HS .50 is a single-shot bolt-action rifle. It has no built-in magazine, and 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 brake that reduces recoil significantly, and a Picatinny rail for the installation of various optics.
