My worry is that with this system, one of G&G's main selling points (the cost effective Combat machine rifles) will be rendered invalid due to increased production costs and therefore a higher RRP.
If G&G have a simple, cheap way of making those complex components without scrimping on quality, then hats off to them; they'll retain the CM range's lower price and the rifles will be much more fun to use, and much cooler than the normal AEGs in the G&G range.
However it does seem as if a lot of problems will arise from over complicating a simple AEG. The split gearbox and quick change spring system should be fine, so should the cocking handle and bolt stop assembly- it's the electronics I'm worried about. G&G's MOSFET switches in their Gen 3 Top Techs have a notorious reputation, although I think they only blew because idiots slapped an 11.1V LiPo into them when they were only really designed for lower voltages. They are integrated systems anyway, and not aftermarket 'FET quality.
