Not an SBR until it's attached to something. Until then, it's only an upper. It's not up to the company to decide what you do with your NFA Items. It's up to the end user. If I want to purchase a 14.5" barrel, or an 11.5" barrel, or a 7.5" complete upper, it's none of that company's business what I do with it. Just an upper, or even a barrel, is not an NFA Item by itself. When I'm looking at stuff like that online, I appreciate the company listing a warning that says "NFA Items are your responsibility," et al. When I see a company that lists a 11.5" barrel, and tells you you can't buy it because it's an NFA Item, then they tel me I need to order from a dealer - I don't buy that item from them at all. They have NO idea whether I'm building a legal SBR, or a pistol from that part - nor should they care. ATF says you can own it without a purchase-restriction, to the company shouldn't be placing a restriction on the individual. I don't like the fact that YHM does this - but I still buy from them, once in awhile. Most of the time, if I'm looking for a YHM part, I buy it from a vendor. For other companies that have this policy, I don't and won't even buy from them. Perfect example: http://yhm.net/index.php?main_page=product_info&cPath=17_29_58&products_id=400 That's BS. That barrel isn't part of a controlled item until I make it into a rifle, without a tax stamp. I can buy that, legally, and have it shipped straight to my house, and build a completely legal AR pistol out of it. I don't need a Class 3 Dealer to do that, not do I need any kind of ATF approval. Companies that do that just suck. I don't like that YHM does it, and I keep supporting them anyway - it's a personal-confusion kinda thing... :o <dontknow>
