Guns America is one of the bigger online gun "middlemen". I would trust using them, if it's the rifle you want at the right price I say go for it.
By the way obewan, I don't know if you're a college football fan, but I saw you're from Ann Arbor, MI. I live near a little town called Boone, NC. Home to a little school called Appalachian State, ever heard of it? Sorry I couldn't resist
