The Steyr .50 HS is the most recent development of the famous Austrian arms manufacturer, the SteyrMannlicher Gmbh & Co KG. First displayed at the ShotShow-2004 (February2004, Las-Vegas, USA), this single shot rifle is primary intended for anti-material applications and counter-sniping. The Steyr .50HS is available in two calibers, the old and venerable .50BMG and the apparently new .460Steyr (on which so far no data were obtained).
The Steyr .50 HS is a single shot rifle,with manually operated, rotating bolt with two large locking lugs at the front.The two-stage trigger is factory set to 4lbs (1.8kg). The buttstock is adjustable for length of pull, the cheekpiece is also adjustable. Heavy barrel is partially fluted and fitted with effective muzzle brake. Steyr .50 HS has no iron sights; the MilStd Picatinny rail is standard. Rifle is not intended to be fired off-hand; it is fitted with integral folding adjustable bipods.
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.

The biggest differences are it is magazine fed from a 5 round magazine feeding horizontally left from the receiver, has a longer top Picatinny rail with more Picatinny rails on the side, an adjustable cheekpiece, a newly designed fixable bipod and a monopod at the buttstock.
