I was over at Impact Guns here in the Kearns area and I asked the guy there about these. He said he had a bunch of them, but they went as fast as they came in.
He doesn't know when he'll be getting more in either. He did say check on their website periodically and whatever is listed there can be delivered to either the Ogden or Salt Lake store for pickup.
Your best bet is probably gunbroker.com and an FFL transfer. Or...if you have your C&R I would imagine this rifle would qualify as a C&R wouldn't it?
