I was recently given a 552 by my grandfather. It was given to him by his brother back in the early 80s and has sat in his closet since. He has never shot the rifle but it looked a bit dusty so I decided to clean it up. After cleaning I noticed that there were two small cracks near the front sight. Both whe 180 degrees apart and I can feel a slight bulge. Also, using a ruler the barrel seems to turn to the right. Does anyone know where I can find a replacement barrel? I've looked and so far I've found a parkerized barrel. So far my only other choice is to send it to Remington. I'd like to keep it as much original as possible and keep the old barrel. Not sure if Remington would do that. Any thoughts fellow INGOers?
