I have a stock UMAREX/VFC HK416 and cannot fit Magpul PTS PMAG green label 75 rounds and Genuine PMAG PTS 120 rounds.

Doesn't lock on the mag catch and doesn't feed. Magwell fitment seems ok but the mag doesn't go deep enough to make the catch lock on the mag.

Magpul are stating that their PTS PMAG should work in VFC HK416.

I was thinking of replacing the lower receiver by a standard VFC M4.
