Recently I picked up a Mossberg 500 3-Barrel combo shotgun for use with my ammunition testing and development.  It's a very unique package that includes two smoothbore barrels, a rifled barrel, as well as a full set of chokes.  Designed as an all-in-one solution for hunters, this package includes just about everything you'll need for a variety of different game, from fowl to fauna, at an unbeatable price.
