Spetz,  The legal legnth of a shotgun is 18 in Washington State. I would look into it where you are from since that is a federal offense if the barrel is too short. Also, if money is not an option look in the Colt CAR-15 w/ 16 barrel and colapsible stock. You will never go back to a regular rifle. Can you give us some more info on the range finders though? Like a website or something.     14/88  JT
