The UBS in MGS4, while technically a Remington 870, lacks M203 style mounting brackets, instead attaching via an RIS mount, and as such isn't a Masterkey. To my knowledge, no such configuration of the Masterkey exists.

Actually, that one is a Masterkey, albeit with the upper parts of the mounting missing. You can actually see at the front of the "rail adaptor" is the point where the missing front bracket is supposed to fit.

I guess that was done because, as you see in the image, the bracket doesn't physically fit on the rifle model when the suppressor is attached. I'll have to check if it's there if you detach the suppressor. Sticking a UBS with an obvious bracket mounting on a railed handguard is just one of those things that works a lot better in a videogame than it does in real life.
