Shoulda hit up MidwayUSA yesterday when you made your post. They had one style BCG in stock. Unfortunately, gone today....
I think I saw it.. was it that AR-STONER Nickle Boron plated one? It had awful reviews, so I passed on that. If there was another one, I must have missed it. I'm not in a huge rush. It'll take a while for my upper to come in, so I'll keep an eye out.
Thanks for that link 'accident'! Never knew of that site... I'll have to keep an eye on that one.
