OP - I don't own the rifle in question but just thinking about your questions. "Does the rifle live up to it's MOA guarantee?" Hopefully it does. If it does not, it's a guarantee, send it back.
From what I know of this particular model, it is a limited edition run (LWRC seems to like the limited edition AR deal, I remember the Leonidas deal some time ago). Anyhow, I think if you're buying this rifle, it is because you want a piece of the limited edition. If you don't care about that, but you do care about accuracy, there's way more fish in the sea than that LWRC.
At the end of the day, it's going to be a very nice rifle. If you want a 7.62-based rifle that is piston driven, has a slick color about it and a swirly barrel, grab it.
Just make sure to give us a rundown once you do.
