BoGs, Need you info? Which gunstores (or BoGs) are selling USGI-quality aluminum M16 magazines 30-rounders? I've seen my local gunstore selling M16 mags, but they are either non-USGI quality or immitations of OKay mags. Best if they are still in plastic wrappers or with authentic CAGE Codes (US DOD Contract numbers). Thanks in advance. - j.
