The main problem with Ceracoating and AR, most
'coaters" want you to bring the gun disassembled, they coat the needed parts. Then you put it back together.
I don't have all the correct tools or the knowledge to do it. I know , its bad to own a gun and not know how to disassemble and re- assemble while blindfolded but hell....
