I'm guessing it's a USC base with a facelift since all actual UMP's are papered as auotmatics and thus not available for civilian consumption. Neat concept though. Did it get a mag cahgeover as well. I know many will get it changed to accept alternate magazines that are more readily available.
Ya it is a USC base. Unfortunatly fully autos are 25,000 and civis cant get them, becuase they are postban. It did not a get a mag change, I am buying the seperate parts so Ican get a 9mm, 40sw, 10m, and 22lr. itll cost some but I think itll be a fun gun to shoot whenever.. O well when I get it for keeps, ill post a range report, and defnitaly give u all some more porn..
