Mossberg's 500 pump-action shotguns offer an amazing amount of gun for an unbeatable price. The variety of stock, barrel and finish options alone would assure the place of the 500 in the hearts of outdoorsmen. The 500 is built to the same uncompromising mil-specs as the renowned Mossberg 590. Then a host of features are introduced - Quiet Carry dual-action bars, 3" chambers and an ambidextrous safety, to name a few. A simple change of barrel and/or choke tubes is all that's required to take one shotgun from upland birds to waterfowl, to turkey, to deer. The Field/Security model features a 28" ported barrel with a ventilated rib, dual bead sights, and Accu-Set chokes. Also, an 18-1/2" barrel with a front bead sight and cylinder bore.
