The Mossberg 500 has always been an iconic shotgun, both for hunting and home defense. The release of Mossberg's innovative FLEX system has given new life to a time-tested design—one gun can serve multiple roles, from tactical defense platform to turkey shotgun.

Featuring Mossberg's Tool-less Locking System (TLS), the 500 FLEX can be configured to handle a variety of shooting tasks in mere moments. Barrels, stocks, forends and recoil pads can be swapped out with little effort, allowing one shotgun to do the duties two, three or even more. And if you're going to pick one shotgun to do it all with, why not one of the most reliable models on the market?
