Mossberg's 500 All Purpose Field shotgun has a variety of stock, barrel and finish options. First and foremost, 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, ambidextrous safety, and a Accu-Set of tubes. (Except for 410 Models) to name a few.
