If you look at a 416 and an M4 side by side, you'll see the front of the mag well is sightly slanted on the M4 where the 416 is more straight. Pmags will hit the lowered part on the 416 magwell and usually fail to lock in. I was able to fix this on my G&G 416 by dremeling the front of the magwell a bit.
As for the VFC 416, you probably need to file the sides of the magwell so they'll drop free. I'd highly suggest separating the upper and lower and taking a file to the inside, and if you're being super paranoid, tape off the air nozzle so filings are less likely to get in your GB. Separating the upper/lower will also help stop filings from getting in the hop-up.
