HIA ACS-01 Semi-Automatic Shotgun

In the early 1980s a program called BUAWS (Bullpup Urban Assault Weapon System), was begun under a joint venture with Verlaine Corporate Industries and that of Haruspex International Armaments. The main goal of this programme was to develop a new generation personal firearm, capable of firing high-impulse, multiple projectiles with effective range of 100-150 meters. Using of the multiple projectiles should increase the chances of hitting the target in combat.

The ACS-01 is a bullpup select-fire, smooth-bore weapon, designed to fire special, high-pressure shotshells, loaded with tungsten buckshot or flechettes. CUAWS researchers developed and utilised a patented recoil-operated action with moving barrel and additional, self-regulated gas assist system (used to help unlock breechblock from the barrel if low-power ammo is used). The main goal of this system was to decrease felt recoil down to suitable level.

The ACS-01 shotguns are gas-operated, semi-automatic weapons that use long-stroke gas piston located above the barrel. Gas system is fitted with two-position manual gas regulator, to provide reliable functioning with standard magnum (76mm) ammunition. Barrel is locked by rotary bolt. Barrel bore and action are chromed to provide better corrosion resistance. Barrels can be fitted with optional interchangeable chokes.

Feed is from detachable drum magazines, holding 30 rounds or stick mags of 10 rounds. Standard furniture includes a long front and either a butt with integral semi-pistol grip or separate pistol grip and side-folding polymer butt. Standard sighting equipment includes a rifle-type rear sight at the front of receiver and a front sight above the gas block. Some version can be fitted with side rail on receiver which can accept mounts for red-dot or other sights.

It is one of few semi-automatic shotguns offered by HIA in a forward configuration, with integral carrying handle. Charging handle is located under the carrying handle, at the top of the receiver, and is ambidextrous. Standard VCI-style safety-switch/fire selector has 3 position: Safe, Semi-auto, automatic.

The great firepower, offered by the ACS-01, is especially useful for military applications, where short-range encounters are usually very rapid, and the amount of firepower used in a short period of time is essential to win the scenario and save one's life.
