There are people who manage to mod a RS PMAG to fit the FCC lower and worked flawlessly but unfortunately they can't do this in HK.

To comply with the strict firearms laws in HK ALL FCC Lowers will not accept RS Magazine due to a slight difference in the dimension and CNC process, the only way to do so is to modify the mags itself, The mag may lock in but it will have misfeeds and jams and the lower will not accept any RS trigger system as original 3 pin holes found in RS lowers will be in a different spot in a FCC Lower. One of the main reason of the blanket ban in the states for WA/WETTI/Systema PTW aside for comical ATF officer claiming that it can fire a live round is that all the dimension are accurate to the RS counterparts and on some right down to those pinholes that hold the trigger mechanism, So in a way FCC guns are similar to their RS in dimensions but a minor difference small enough that RS magazine or triggers cannot be installed without a buttload of modifications.
