Interesting read. ATF drops case due to judges potential ruling that would set case law that AR lowers don't fit the federal laws definition of a firearm. Apparently ATF interpretation of the federal law doesn't stand up in court, it would have to be re-defined and written in to law........hmmm. It's early, so my reading comprehension may be lacking this morning. If I post a news link this will be moved, so someone ask for it and I'll post it so you can figure out what the article means.
