Fabarm semi-automatic shotguns use a robust and simple gas-operating system, with fewer parts than other gas-operated shotguns, making them easy to clean and maintain. The recoil spring surrounds the magazine tube and works in the same axis and parallel to the barrel ensuring the balance of the gun remains unchanged during firing. By using such a rugged and simple design, Lion shotguns function reliably with standard 12 gauge shells without adjustment whether they're 2 3/4-inch target loads or powerful 3-inch magnums. The Rex Lion is a limited edition of the Gold Lion Mark II with a black- and silver-finished receiver with gold medallions and a checkered Turkish walnut stock. This fine Italian-made shotgun features a ventilated rib, a red bar front sight with a green bar rear sight, and a cross-bolt safety and includes a set of four screw-in choke tubes and the original factory hard case. Its wood, metal, and bore are all in good condition.
