Product Summary

The Flex 500 All Purpose series is a modular system of shotguns based on the legendary model 500 with Mossberg's patent-pending Tool-Less Locking System. This system consists of three convenient connecting technologies that come together to bring another level of flexibility to your hunting and sport shooting endeavors. One locking pen is for the stock, one for the forend, and one for the recoil pad.

This combo includes a 24" fully-rifled deer barrel with a cantilever scope base and an 18-1/2" tactical barrel, pistol grip, and tri-railed tactical forend that allow you to go from hunt-ready to protection-ready in a matter of minutes. The shotgun comes painted in OD-green and Mossy Oak Break-Up Infinity camo and sports Mossberg's Lightning Pump Action (LPA) adjustable trigger.
