The Steyr IWS 2000 is an Austrian single-shot bolt-action
Steyr Mannlicher. IWS stands for Infantry Weapon System. Unlike other anti-tank rifle designs, it has a smoothbore barrel. This facilitates higher projectile velocities and allows a longer barrel service life, but the lack of gyroscopic spin-stabilization requires the projectile to have aerodynamic stabilizing fins instead. The IWS is chambered in a 15.2×169 mm armor-piercing fin-stabilized discarding-sabot
cartridge, and is the first man-portable rifle to use this type of ammunition.
The first variant of the weapon was the proposed AMR 5075 (AMR standing for anti-materiel rifle). It was to fire the same type of ammunition as the IWS 2000 and to use a 5-round detachable box magazine. However, that version did not pass the proposal stage.
Design
The weapon is based on a 25 cm (9+3⁄4 in)
polymers
to increase manageability and cut down on weight. The smoothbore barrel is easily detached and packed away for increased mobility. The APFSDS round is inserted from the side of the weapon, much like with usual single-shot rifles.
Ammunition
The projectile is a 20-gram, 15.2 mm fin-stabilized discarding-sabot type with armor-piercing capability which the IWS 2000 was specifically designed to fire only. It contains a dart-shaped penetrator of either
rolled homogeneous armor at a range of 1,000 m, as well as causing secondary fragmentation. The cartridge consists of a plastic case, a steel head, and a plastic sabot shell around the penetrator, and has a maximum diameter of 26 millimeters, at its base. The complete projectile assembly with its four sabot
segments weighs 35 grams.
