I couldn't find a post that will answer my question so I'll ask you who's done the conversion from USC to UMP, or just happened to try it.
Will the USC rubber buttpad fit the UMP stock? I've came across a used UMP stock for sale but is missing the rubber piece.
I want to get it for my future conversion but unsure if the rubber from my USC fit it.

Thanks all.

I don't think they are the same but I can tell you from taking the USC
rubber off that it is melted into place. I think you would have more
luck with an aftermarket rubber piece that you could somehow screw into
place, if you could do that.
