I finally saw one of these yesterday at the local Cabela's. A .300 WSM 'Stainless' with walnut stock. The barreled action is indeed a Montana Rifle Company product (model 1999 action) rebadged as a CZ. The action and barrel appeared to have an applied finish over a bead blasted surface. The stock was an exceptional piece of wood and nicely checkered, with a glossier finish than CZ normally uses, almost Browning-like. It was without the Monte Carlo cheek piece Montana Rifle uses. The combination of the two was a bit incongruous; matte metalwork and glossy wood. Perhaps CZ USA in Kansas bought the actions and had them stocked separately. I understand that these ultimately sold new for less than a typical Montana Rifle at the time, and actually for not much more than one of their actions alone sold for, which probably didn't bode well for a mutually beneficial partnership. At any rate, when new, it would have been a nice gun for the money... If you like the Winchester Short Magnum chambering, which never appealed to me.
Which brings me to my next point. Cabela's usually over-value their used guns, and this was no exception; $899. Yes, it had a Leupold VX I 3-9x40 scope and rings mounted, but those sell used for $100-150 at best around here and silver scopes are harder to move. Ask them to take it off and sell the rifle for less and they revert to 'used optics add little value to the gun' bs. So as a hunting rifle, the total package is not an unreasonable deal, but for the same money someone could buy a new Montana Rifle (they're on sale for $900), or a new CZ 550 for $739, with rings, and put the savings toward their choice of scopes. If someone is looking for one of these as some sort of collectible or for speculation, Cabela's mark-up has already taken up any sort of appreciation it may have had.
