VFC HK417 AEG with accessories. There goes my airsoft budget for this month and the next few will all be spent on new motor, inner barrel, hop up, piston assembly, air nozzle, cylinder head and Gate Titan.
Finally got my SRC TCC M4 to a point that it works and looks good doing it.
When I first got it the wiring was perishing, the shimming was pretty terrible and the air seal was non existent. A reshim, rewire, new O ring and a MOSFET later and everything's working smoothly and I have a new rail system, pistol grip and stock.
