i got a mossberg 500 (12 gauge) its got a regular stock and a rifled barrel. pretty standard if you ask me. but im wanting to add some stuff to it that would make it a better gun. i need some ideas. i use this gun for hunting/home defense so i dont wanna shorten the barrel. im not looking to add a site cause i dont see a reason behind it since its just a shotgun but i want to do something to make it a little more special if you get what im saying.
