Could use some cleaning up, and quit using it for a bearing driver or for breaking glass & concrete.
Oh and the bore could use some TLC too. Did you acquire this from a gang member that threw it down the street?
From the testing I've seen, a crown will only matter further downrange than you'll ever have to worry about. The muzzle can be cut with a hacksaw at a random 45ish degree angle and it won't noticeably affect accuracy, I know it sounds crazy, but the demonstrations and testing are pretty easy to watch online, Google-fu... If that was MY barrel, I'd take this opportunity to polish the finish off the whole thing and bring it to a nice, shiny finish for a unique look 😉Yes it's damaged. You can clean it up, but you will take the finish off. Does it effect accuracy... IDK.
