Black Aces Tactical Custom pump-action shotguns... - Weapons Lover
Black Aces TacticalCustom pump-action shotguns that are built on magazine fed receivers; they are not Remington 870 or Mossberg 500’s. Black Aces Tactical has different models, this one I think is their Pro Series Stinger. It uses Saiga 12 mags and drums but they have to be slightly modified in order to work in the pump-action receiver, but Black Aces does offer already tuned mags for sale.
