You must use an upper that has widening cuts to accept the larger width MP5 Magazines — We sell three versions of C-5 Uppers that can be found HERE.
ETS magazines may require slight sanding to ensure proper fitment due to variations from factory H&K Magazines.  We have yet to find any fitment issues with HK, Zenith, or KCI mags.
