Design and featuresEdit

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 .460Edit

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 M1Edit

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 SayyadEdit

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]
