The internal switch assembly also does not have contacts that contact the selector plate, it instead uses a direct circuit (complete in the unit) with the 2nd moving contact piece the only piece required to complete the circuit.

I talked to abanana over the phone, my suspicions lie in carbon built up contacts on the 2nd moving contact piece. Ive had the same issue on 2 VFC Guns from Big Shark already, and abanana is using lipo in his gun, which increases the buildup even more.

Forget filing the carbon buildup off, Ive tried, and somehow they will work during assembly (tested with multimeter), but after a couple shots, they cease to function again. Taro Bear's friend Gaivern (the owner of the VFC M4 Sopmod) i fixed, I dissassembled and reassembled his gun over 6-7 times. I just cant explain it, the metal contacts are touching, but no current is transferring. After modifying a TM compatable switch assembly, his gun has been functioning flawlessly every since.

That was far beyond my understanding however I know my way around the gun enough to know where to take pictures, I'll be posting my findings, hopefully next weekend I'll get into the thick of it. Taking bets...
