What is in the powder that makes ones eyes burn and smells similar to Ammonium ? The guy who owned the M16 said it's cordite that makes your eyes tear when you shoot the full auto... True?
This^ . CLP burns off too and smells ammonia-ish.Cleaning solvents are burn off as the Full Auto gets hot ,if to much or the wrong kind has been used. Break Free CLP works well. Tell your cordite friend to change his cleaning methods.
