A couple of folks have asked for pictures of why my hydro-dipped rifle looks like after a few thousand rounds through it -- here they are.
The dipping was done by a local company that specializes in this kind of work. They were incredibly nice and really great people, but I am not going to post their name here as I don't want people to think that the problem was with the company or their process.
Once the rifle was dipped I coated the whole thing with a couple of coats of Duracoat clear, and gave even more coats to areas that I thought would really wear (hand guard, selector, grip, trigger guard, etc..)
There are more pictures - but I think you can get the idea. Bottom line is don't hydrodip anything you are actually going to use. Yes it looks pretty, but it doesn't really hold up.
