Does anyone have any experience with the New England Pumps? I am interested in getting one for HD. I think it will be cheaper to buy one with a longer barrel used and cut it down to 18" than to try to find one new with an 18" barrel. Also, since these guns are an 870 copy does anyone know if Remington mag extensions will work on these guns? I have thought about buying a Winchester or Remington and cutting it down but I hate to do that to a more expensive gun. Any input is appreciated
