Scroll down and you'll also see a picture of one with no rail; Talley LWs holding the scope.
Hopefully, that photo does show an 2022 action option with no rail, rather than an image of a 1999 action recycled from the old MRC archives.
I'm almost 100% certain that's the new action, the old M1999 action didn't have the scalloping where the banner and serial number is located like in the pic. The pictures with the two piece picatinny rail look like it's machined integral to the action with a cutout in the center to lighten it. It looks like they're offering both the rail option and no rail which is smart.
The old Montana 1999 actions were cast by Pine Tree casting which was a division of Ruger. They were nice but too heavy, there was a lot of unnecessary metal in them. These being fully machined it looks like they did some work to knock out the parts that added weight but no functional benefit. That's great, weight for no reason is a negative. You can always add weight back if it's too light. Most custom rifles come in too heavy when guys start adding heavy scopes, heavy fiberglass stocks and larger contour barrels. It's easy to make a rifle that'll shoot, it's harder to make one that'll shoot and doesn't handle like a train axle.
