Steyr IWS 2000


Anti-Materiel Rifle (AMR)


Austria | 1999



"The Steyr IWS 2000 is noteworthy for its use of Armor Piercing Fin Stabilized Discarding Sabot ammunition."

The Steyr IWS 2000 (IWS = "Infantry Weapon System 2000") was a proposed anti-material rifle born out of a 1980s initiative by the Steyr Mannlicher concern of Austria. The system was unique in its design by applying various "non-rifle" elements to its function and action. The ISW 2000 was designed with principles found in shotguns and field artillery pieces to produce the required recoil dampening features required of firing such a large cartridge. While chambered for the unique fin-stabilized discarding sabot 15.2x169mm cartridge the IWS 2000 was evolved into the AMR 5075 (AMR = "Anti-Material Rifle") variant chambered for the readily-available 14.5mm cartridge. As of this writing (2012), the IWS2000 and AMR 5075 have yet to be produced in large numbers and remain, more or less, "in development".

The external configuration of the IWS 2000 consisted of a large shoulder stock with an enclosed grip-and-trigger unit. An adjustable stand was fitted under the stock and managed by twisting a knob at the rear. The receiver of the weapon was largely tubular, supported by a folding bipod assembly. The 10x optical arrangement was set along the top of the weapon in the usual way. The removable barrel protruded a distance ahead and was capped by a multi-baffled muzzle brake. The barrel was further seated in a recoil-dampening sleeve to content with the inherently violent recoil effects of firing such a large caliber round. Overall weight was 40lbs with a running length of 71 inches (47-inch barrel). The weapon fired from a 5-round detachable box magazine through a long-recoil/rotating bolt action. The long recoil action was similar to that as found in modern shotguns, a proven recoil dampener. Effective range was within 1,000 yards with a maximum listed range of 2,700 yards. Magazines were fed into a well along the right side of the weapon body. Interestingly, the IWS 2000 made use of a smoothbore barrel as opposed to a rifled design common to all firearms categorized as "rifles".

While not in serial production, the data accrued during development of these two rifles may still influence future Steyr Mannlicher projects to come.
