I picked this m70 up a few weeks ago. Its a 1948 SN but with barrel dated 47. I havent made up my mind if i will drill the rear bridge or put a peep on it. The barrel passed the eye test but after shooting it a few times I have had great difficulty getting the barrel clean. I have no idea how many patches have gone through it but a wet patch never comes out clean. I borrowed a borecam and these are the pics I have. It looks pretty good other than what I assume is a small amount of pitting? I'd appreciate the community's thoughts.
