Design
The weapon is based on a long recoil mechanism. This mechanism, usually found in shotguns, helps manage the heavy recoil forces of the 15.2 mm Steyr APFSDS round due to its damping effect that allows for force distribution over a longer period of time. After firing, the barrel recoils into a shock-absorbing hydro-pneumatic sleeve much like those found on a LG 1 Mark II 105 mm Howitzer. The IWS 2000 also uses a multi-baffle muzzle brake to distribute muzzle energy and further reduce recoil, similar to that used on the D-30 2A18M 122 mm towed howitzer. The entire rifle body is made up of a combination of high-tension plastics and superlight 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 tungsten carbide or depleted uranium, capable of piercing 40 mm of 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.See also
