[b]I am posting this in this section to get the most views.[/b] I was with a friend and we stopped at one of his friend's house. We were introduced and the conversation turned to guns. He opened his safe and started showing me his collection. As it turns out, he had an old-looking AR-15 that he said he picked up about 6 years ago. The upper was preban-style, but ratty looking. The lower looked like new. Anyway, he said he was looking at an upper at a pawnshop (a postban, although this guy knows nothing about the pre/post issue) to replace the trashed one. I think the lower is a PRE-BAN. I think he will sell me the lower for the cost of a postban (which he will buy). He will still be legal, as the new upper he is looking at is postban. The serial # is EA 039XXX. Is this Essential Arms (I hope!) or Eagle Arms? According to what little I know, ALL Essential Arms lowers are PREBAN. Thanks.
