ok I know not what this is set up for, but was hoping might get lucky here. I need some M4-0.5x15mm set screws with nuts to set up adjustable gas for a Swedish gun. I've look at all the common and most uncommon sources and coming up with blank. being the lazy no good sort I am trying to not have to make them. if anyone has a source would appreciate it. and thanks in advance.
