Umarex Umarex Zelos picatinny rail out of tolerance?

I just found this thread. Yeah, it is really maddening to purposely switch all your stuff to Picatinny so that you can scope swap and find out that some companies just don't follow the standard. I'm still hopping mad about this. The o.e.m for the Umarex Zelos and the Barra 250z, are of course, SPA. It is very good to know who you can trust to follow a standard, and who you can't. SPA should not have to be told that they have to follow the standard for the complete length of the rail, on either side of a cut-out, but the they obviously need just that! The handholding and oversight, needed to get them to do the obvious, would drive me nuts, as a contractor.
