I had to cringe when I saw him running the drill rod through the barrel. There are proper brushes out there for the attempted rescue of barrels that are heavily rusted or fouled. Sometimes they aren't near as bad as they look either so it's best to take it easy until you know what you're looking at. I guess he didn't hurt it but..... The scope mount just dropped on and collimated perfectly without any issues? That looked like an excellent DRP bracket but they still need proper fitting/collimating if the rifle is mismatched. My hands are still sore from doing one so I just thought I'd mention it. Other than that, I appreciate his effort at producing a video.
