Im brand new at hunting with flint lock in pennsylvania. And i would like to know if it is legal to use a scope during the late season of flint lock. If so I have a 54. Thomson Hawkens and would like to know what would be a good scope to put on it. I would prefer to use iron sights but they really play with my eyes and sometimes its hard for me to get a good shot. Any info would be highly appreciated. Thanks
