Technical description.
The AR-3 is a gas operated, magazine fed, air cooling selective fire rifle. The gas action features a short piston stroke, rotating bolt locking mechanism, and adjustable gas regulator. The gas chamber and piston are located above the barrel, and the piston has the cupped head and its own return spring. The square-shaped bolt carrier is mounted inside the receiver on two guide rods, with each rod carrying its own return spring. Both rods are linked by the special end plates so the whole bolt / bolt carrier / return springs / guide rods assembly can be removed from the rifle as a single unit, which greatly simplifies the field maintenance. The rotating bolt is rotated by the bolt pin, which is engaged in the curved cam track, cut in the bolt carrier. The charging handle is fixed to the right side of the bolt carrier and reciprocates when gun is fired.The receiver is made from stamped sheet steel and consists of two parts - upper and lower. Both halves of the receiver are hinged one to another at the front of the receiver. The upper and lower parts are interlocked by the rear ends of the bolt carrier guide rods.
