"Awesome wiring, gearbox itself, qc spring change system, microswitch trigger, and it is honestly a great gearbox. BUT, this thing has absolute trash airseal, replace the whole piston and cylinder assembly out of the box. Also, i tried it in a g&g, jg, g&p and vfc receivers. it only worked in the vfc receiver without modification. idk if it could be fit with modification.

"OK, so this gearbox will have fitting issues. G&G receivers will not work because of the QC spring design. I have to cut the top of a black ops m4 lower reciever. It also bulges the lower. Next, the airseal is HORRIBLE. I chronoed at 170-210 fps. The internals seem ok, but will need work. I wouldn't buy unless you know how to tech. The micro switch is awesome though, the trigger response is really good.
