The Steyr HS .50 is a .50 BMG single-shot anti-materiel sniper rifle manufactured by Steyr Mannlicher. The rifle has been widely exported; in addition, Iran produces an unlicensed copy under the name AM-50 Sayyad, while Syria reportedly began producing second unlicensed copy, dubbed the Golan S-01 in 2019.

Design and features[edit]

The Steyr HS .50 is a single-shot bolt-action rifle. It has no built-in magazine so 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 provides excellent accuracy at an effective range up to 1,500 m. It has an adjustable bi-pod, a highly efficient muzzle brake which reduces recoil substantially to increase shooting comfort and a Picatinny rail for installation of various optics.

However, due to customer demand, a recent change to the HS .50 has included a 5-round detachable magazine that can be inserted on the left-hand side of the rifle much similar to the Denel NTW-20


HS .460[edit]

The rifle is also available in the proprietary .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. The .460 caliber version is known as the HS .460.

HS .50 M1[edit]

The HS .50 M1 is an evolution of the HS .50. The biggest differences are: 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[edit]

Iran produces an unlicensed version under the name AM-50 Sayyad.[4] Because of its wide exports, AM-50 rifles have also been sold to or captured by many groups opposed to Iran, such as Syrian rebels.[3]

Golan S-01[edit]

In June 2019, 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. It is reportedly manufactured by the Syrian Defence Industries Corporation, a state-run company managed by the Syrian Ministry of Defense. Unlike the original HS .50, the Golan S-01 fires the Soviet 12.7×108mm anti-materiel rifle cartridge.[5] It is slightly heavier than the HS.50, weighing in at 13.5 kg and boasts 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 100mm longer than the HS .50, measuring in at 1,470mm total length.[6]
