Mossberg Model 500 20 Gauge 18.5" Breacher Barrel Factory Demo Pump Action

The Mossberg Model 500 is a proven pump-action platform valued for its straightforward operation, durable construction, and versatile design. This factory-demo example is chambered in 20 gauge and features an 18.5-inch cylinder-bore barrel with a distinctive breacher-style muzzle device. It accepts both 2¾-inch and 3-inch shells.

The black synthetic stock and forearm provide a practical, weather-resistant setup, while the ventilated recoil pad helps provide a comfortable shoulder fit. The extended-length magazine tube complements the compact barrel configuration, although its exact capacity should be confirmed before publication.

This example is technically classified as used because of its factory-demo status, but it remains in excellent condition and appears unfired. It includes the original Mossberg box, owner’s literature, cable lock, and related factory materials.
