I have owned a VFC 416, in fact it was my first gas gun. The externals are superb, however it proved pretty inconsistent in power terms, and unless you fit the TNT barrel and hop kit, it is inaccurate . It had an NPAS, which is fine but temperature plays such a big part in the VFC equation, that you will find it virtually impossible to know what your VFC is going to put out, until you chrono it on the day.
I moved on to MWS, after owning 2 GHKs, which were good, but not in the same league as MWS. I have two MWS: One is an URGI DMR, fully upgraded with a G&P NPAS shooting 1.85 J on 0.45s, which stacks up in accuracy against my TM NGRS HK417 DMR - which is saying something. The other is an Archwick L119, which came fully upgraded with Guns Modify internals - like the URGI it is bloody good, and I have it set for CQB at 1.1J.
The moral of the story is go for MWS, upgrade the nub, and fit a tight bore barrel from the onset, then take it from there...you will not be disappointed.
