Hello. I just got my first model 71. So happy! Four digit serial number. Not a deluxe but came with the bolt peep. The aperture was not factory and was bent during shipping. I would like to know what the tap size would be to clean up the threads and what aperture to look for as close to the original as possible. Thank you for your help. Gary
