the "black" on scopes, air cylinders, rifle actions all vary in shades and texture with different manufacturers and its very difficult finding the right shade of "black" - the birchwood casey pens in gloss isn't too bad a match for the edguns I find. would be great if each manufacturer would sell touch up paint like you see with car paint. To the OP - minor crimp marks aren't too bad if the scope is mounted as then you can't see them but elsewhere could be annoying if you have ocd like me...
