Complete Reinforced Gearbox with Motor for P90 Series Airsoft AEG (Model: Standard)

"Amazing gear box over all, just don't try and take it apart unless you're a pro tech because it's confusing to put back together

"OK so first of all i would say this is a good buy, i put this in my gun and it shot better then the stock king arms gearbox. My only complaint is that the fuse holding box was broken but i easily fix it with some tape.

"Have to pay for bigger spring installation, I would not run a lipo in this, but technically any gun is lipo ready, I would guess you'll strip the gears within a month though, just guestimating. Same for if you get a bigger spring. Anyway the first gearbox I got was defective (the fuse was busted apparently) wtf? So I got back to the store today and exchanged it for a new one. Looked fairly clean, will have to go in to the trigger soon as with all p90s. The rof is slower than my stock Echo1 which I didn't mind, and there was no semi auto function. I plan on swapping over the echo1 components in to this shell anyway, use the rest for spare parts or maybe get another shell and upgrade it. A+ to Evikes service. Gearbox wasn't identically awesome to the echo1 but it will definately work. Great replacement for the price, especially considering a new shell is 25 dollars. My echo 1 gearbox shell broke O.o a chunk on one side of the shell on the spring guide chipped off... the second I screwed the last screw to reattach the trigger assembly... whatevs. Now that I think about it I will probably put the motor from my G&G raider which I'm replacing in to this one, bump up the rof, since i bought a tune up kit and stuff for the CM. THANKS EVIKE!!!

"Hey I was wondering what length piston is in here. Because I want to buy this an replace the piston and re-shim everything.
