The mag housing is different. I don't think it'd work.
Which mag housing? The CSA Vz (223) housing is different than the CZ (7.62 x 39) housing?

The XCR is a newer platform by about 5 decades so the ergonomics out of the box are better, that said, on a VZ for pretty cheap, you can have a bolt release, ambi safety, ambi mag release etc and your ergonomics are pretty nice. The VZ has a stipper guide, but the xcr im sure can use a maglula or whatever they are called.
Now buy a colt/RRA/LMT and stick on a gas piston upper with heavy barrel, ambi everything, quad rail etc etc and see where the XCR gets competitive...
