Pretty sure it's advised to stay away from WD40 for lubricating your guns? :L ANyone back me up here?
I know I can clean my barrels with alcohol. Then I would clean them with a barrel cleaning cloth. After this do I lube it? If so with what?White lithium grease, pure silicon grease, pure silicon oil and silicon spray.
Never use wd-40, it destroys rubber parts. And never use regular silicone spray or grease (obviously) in a barrel.
