Tagging back in on this. I ordered one, and didn't open the box until this morning when I got my rifle back from the Smith. I hate it. As soon as I started trying to mount it, I realized that it will not accommodate an mtu profile barrel, comes with no bottom metal of any kind, (and I can't even figure out from the grs sight what bottom metal I'm even supposed to use to fit these things), and it is cheap thin plastic. At over $700, by the time you buy the bottom metal, you can buy a high end complete mdt chasis for about the same money. Not a good value. I'm returning mine and buying an mdt.
