Steyr HS .50 / HS .460

The Steyr HS .50 and the Steyr HS .460 are single-shot anti-materiel rifles manufactured by Steyr Mannlicher and chambered in .50 BMG and .460 Steyr, respectively. Unlicensed variants of the HS. 50 include the AM-50 Sayyad produced by Iran, the Golan S-01 produced by Syria and the Ghoul produced by the Al Qassam Brigades.

Design and features
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.

The original Steyr HS-50 was designed by Heinrich Fortmeier, on behalf of Steyr Arms.

HS .460
The HS .460 is chambered for the .460 Steyr round, developed for markets where ownership of the .50 BMG by private citizens is banned, but .46 rounds are not, such as California.

HS-50
The "HS-50" is a single shot bolt action .50 BMG rifle, with 2 barrel length options (29" / 33"), The rifle comes standard with a 0 MOA picatinny rail

HS-50 M1
The HS .50 M1 is an evolution of the HS .50. It is magazine-fed from a five-round magazine feeding horizontally left from the receiver, has a longer top Picatinny rail and more Picatinny rails on the side, an adjustable cheekpiece, a newly designed fixable bipod, and a monopod at the buttstock.

AM-50 Sayyad
Iran produces an unlicensed version under the name AM-50 Sayyad. The AM-50 has been in production since 2008 and has been widely exported. Because of its wide exports, AM-50 rifles have also been supplied to or captured by groups opposed to Iran, such as Syrian rebels. The AM-50 reportedly has much worse fit and finish than the Steyr HS .50.

On December 21, 2023, Hamas showed video footage of a Hamas fighter manufacturing AM-50s.

Golan S-01
In June 2018, media organizations affiliated with the Syrian government reported that Syria had begun producing an unlicensed variant of the rifle, dubbed the Golan S-01, in reference to the Golan Heights. Its first prototype was issued in 2015. Unlike the original HS .50, the Golan S-01 fires the Soviet 12.7×108mm anti-materiel rifle cartridge. It is slightly heavier than the HS.50, weighing in at 13.5 kg and has an effective firing range of 1,600 meters, a 100-meter improvement over the previous generation of anti-materiel rifles used by the Syrian Army. It is also 100 mm longer than the HS .50, measuring in at 1,470mm total length. It is manufactured by Golan Rifle Plant. In 2023, the SSRC has upgraded the Syrian produced Golan S-01 AMR. New model was introduced with a new stock, box magazine, and scope.

Al-Ghoul
Named after hamas engineer and senior operative Adnan al-Ghoul, this is a Palestinian-made sniper used by Hamas military wing, Al-Qassam brigades. One of the world’s longest sniper rifles with a length of 1.5 meters, it differs from the typical model as it uses 14.5mm and 12.7mm caliber ammunition. Al-Ghoul has a range of 2 km. Hamas first used this rifle in the 2014 Gaza war. The group also stated that these rifles are “evidence of the distinction of its military industries”. Whether the rifle is actually made in Gaza or made in Iran and then brought through Hezbollah is unclear.
