Technical description. The AR-3-SG is a gas operated, magazine fed, air cooling selective fire shotgun based on the AR-3 assault rifle. The gas opoeration is complemented by a manually selectable pump action, which allows firing of low pressure ammunition, such as less lethal tear gas or rubber slug projectiles.

The caseless ammunition consists of either a slug, a flechette bundle, or a shot bundle embedded in a nitrocellulose compound. The cartridge burns in the rifle completely. The ignition charge is a semi conductor using the battery in the stock to ignite the cartridge directly.

This shotgun is capable of firing both the High Explosive Shotgun and Flechette Shotgun rounds.
