I have five NIW USGI M-14 mags. I have opened two mags from this batch, they were both marked O.M. and both function flawlessly in my M-21. You will get five unopened mags that are sealed individually in moisture proof military wrappers. $250.00 delivered to you via Priority US Mail. If the politicians where you live don't trust you with this type of evil device please don't try to buy them.
