    Experimental System

    In the mid-1980s, the engineers of the Austrian company Steyr-Mannlicher AG began to develop a large-caliber "protivomaterialnogo" (Anti-Materiel) weapons designed to destroy enemy materiel - light armored vehicles, fortifications, aircraft and other equipment at sites, helicopters, radar cabins, etc.

    automatic rifle Steyr IWS 2000 is a set of "rifle-cartridge" of smooth-bore semi-automatic shotgun, made in bullpup configuration and special cartridge with a bullet piercing feathered.

    Initially experiments were performed with a weapon chambered for caliber 12.7 mm. subcaliber with bullets. During the experiments it was found that greater efficiency provide ammunition type OBPS (feathered armor-piercing projectiles), representing feathered arrow from a tungsten alloy. Was released on a small experimental series shotguns (rifles will not name) caliber 14.5 mm. under the designation Steyr AMR 5075. During their testing gauge was increased even more, and the final nominal caliber was 15.2 millimeters.

    system consisting of a smooth-bore semi-automatic shotgun and a special cartridge with a bullet piercing feathered called Steyr IWS 2000.

    Chuck Steyr IWS 2000 has a plastic sleeve with a bottle shaped steel Donets. In the head part is a detachable plastic container inside which is a feathered arrow from tungsten. Boom diameter - 5.5 mm., Weight according to different sources - from 20 to 35 grams, the initial velocity - 1450 meters per second. At a distance of 1000 meters, The arrow hit 40 mm. homogeneous armor steel and provides a significant zapregradnoe splinter effect. Due to the high initial velocity and good aerodynamics when shooting arrows at a distance of 1000 meters trajectory in its entirety does not rise above 800 mm. above the line of sight. Steyr IWS 2000 is not intended for use against individuals, but in case of contact with a person, even at large distances the result will be very impressive, with almost guaranteed fatal.

    Experimental System

    gun itself (or, to put it correctly, "smoothbore rifle") Steyr IWS 2000 is built on the basis of automation with long recoil. After the shot the trunk, locked the gate, inside the receiver is rolled back by about 20 centimeters. Then the gate unlocked, turning relatively trunk. Trunk back to the forward position, removing and discarding the spent case, the shutter at that time remains in place. After the arrival of the trunk in the forward position the shutter is automatically released, goes forward, feeding a new cartridge, and at the end of his turn closes the trunk.

    To compensate

    exceptionally large recoil energy besides rollback trunk stretching out on a sufficiently long period of time, are also a big muzzle brake compensator and oil-air shock absorber, located around the barrel.

    Receiver Boxes and weapons made with extensive use of plastic to reduce weight.

    Steyr IWS 2000 is standard equipped with an optical sight and 10X.

    weapon itself is made in bullpup configuration and box magazine inserted to the right at an angle to the horizontal (about 45 degrees down).

    Steyr IWS 2000 is equipped with a bipod and extra pull-out support under the butt. For transportation trunk separated from the receiver, and weapons packed in two bales that are transported calculation weapons.

    In the 1990s, the system IWS 2000 was ready for mass production and formulation adopted, but new weapons no hurry to buy (apparently including because Steyr IWS 2000 requires a completely new Custom cartridge) and remaining in the category "advanced development".

    However, individual data, by 1998, some U.S. special forces were equipped with a small number of rifles Steyr IWS 2000, which were used in various martial conflict.
