OK I have been thinking of getting a non stainless fluted/theaded 24" bull barrel to replace my barrel with. Problem is this rifle will shoot one ragged hole at 100yards. The next barrel I get may not. So the question is how can I make this one match the rifle in a way that will last, but not have any negative affects. I have some scrap stainless that I tried an etching primer on and flat black krylon but that's not holding at all, I can rub most of it off with just a welding glove. Is there a primer made just for stainless, or is this impossible to have a some what durable finish on stainless. I just don't like shinny on a rifle.
