Hello guys. I just got a borescope (Lyman Borecam) and took some pictures of the barrel. The first three pictures are of the muzzle/crown area. The second three are of the middle of the barrel. The rifle is a Remington 700 20" barrel with a suppressor. I been having this rifle for the last two to three years, but an older gentleman had this rifle for approximately fifteen years. Do you guys think it is time for a new barrel?
