Saw this tonight while cleaning her over. shot last about 4 mos now. Usually meticulous re cleaning with Hoppes 9. Last outing was in August after sending about 20 rounds. Did not swab after and sat in safe without dehumidifying agents. I was initially drawn to the exterior pitting, which I rubbed mildly with a surgical blade… but noticed that it was beyond just the surface. But on a closer observation, I see the copper colored irregularly shaped (what appears to be oxidation) or whatever it may be in the rifling. I don’t see anywhere else but then I don’t have a bore scope. HELP…
I almost sold my left nut for this MPA and horribly bothered. Thanks in advance All…
