My new ptac bolt carrier group doesn't cycle cleanly. I forget who, but someone posted an ar bolt slick up how to, I think I'll give that a shot.
Aside for the obvious of looking for tooling marks and burrs what's a good way to identify what needs to be smoothed out? I was thinking of a very light misting of white spray paint, letting that dry, then cycling the rifle a couple hundred times to see where it's wearing. Or maybe layout dye?
Any suggestions?
