Was doing a little inventory today and came across these Colt 20rd. mags that I forgot I had. Can any of you AR gurus tell me if they are preban mags? The stamp on the bottom of one of them is 5.56 and the other .223. No manufacture dates on either. Also if they are preban, what states am I legally able to ship to that someone may be able to get some use out of? I know NY is out.
