The Steyr .50 HS is the most recent development of the famous Austrian arms manufacturer, the Steyr Mannlicher Gmbh & Co KG. First displayed at the ShotShow-2004 (February 2004, 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.
