just a heads up, the nozzle included with the prowin gear box is 0.3-0.5mm too long. i had all sorts of feeding issues with the stock nozzle. some of the issues were chopped BBs, BBs rolling out of the barrel, and BBs getting jammed due to them having to squeeze past the nozzle taking the lower lip of the hopup with it. after switching to a Modify M4 airseal nozzle, i have had no more feeding issues at all. im running the prowin in my VFC416 with a 11.1v lipo, so any feeding problems generally ended up with a stripped piston. and as i think back i did have issues with a non-ported cylinder. with a high speed setup you need to make sure your piston can return to full battery before the sector gear re-engages it, if not you will keep stripping pistons and gears.
