We have received a few Mossberg 500 combos- These ones have a rifled slug barrel with attached cantilever scope mount, as well as a vent rib barrel with interchangeable chokes! Rounding out the combo are two different cheek risers for the rear stock, to allow use of the included scope. We had previously only seen the "Camp and Field" combos.
