i'll reiterate. remington 870. it has a lot of after market parts for swapping out components for the task at hand: 28" barrel and a traditional wood stock and forend for clay and hunting, to a 18" barrel with a synthetic pistol grip stock with a synth foreend for HD. I think everything included would run you 400 tops.
