"Great G&P solid feel to the externals. The kit has a terrible piston, I replaced it fast but already saw that it was starting to strip. Gears are good quality. Good motor. A couple external problems are the dust cover wont close and the mag release sometimes gets stuck, although you can fix it quickly. Paired this kit with a G&P buffer tube, G&P outer barrel, and the G&P MOTS hand guard and everything is solid as a rock. When I replaced the gearbox shell with a new retro arms QCS one, I had to sand the upper ever so slightly to get it to fit.

"I have bought 2 of these and also have bought many g&p v2 and3 gearboxes. Even though the piston is the weakest part of the gear box I haven't had any issues with them I also have g&p so com m14 and it is flawless. If you want to shoot 400fps with 20plus rps right out the box g&p m120 8 mm gearboxes and m120 motor combo is the best bang for your buck hands down.

"With this i created the best gun i have ever owned. Get a mosfet with it and be 100% sure that what you have will work with it... Daniel Defense outer and noveske rails work perfect. I don't thing the wires detatch so be sure you buffer tube isnt by g&g because a deans port wont fit through those two small holes. I have a cnc hop up for it and a mosfet and i can guess it is shooting over 25 rps (rounds per second). With an 11.1 this thing destroys and it is still very fast with 9.6.

"standard G&P let down. Although externally this is very nice and they use high-quality internal parts the Achilles heel is the polymer piston. Its not corrected for angle of engagement and failed within a thousand rounds. This is the second G&P product I bought the other was a drop in AK gearbox and it was the same case there as well. if you want something that you are going to be able to put together and just play this is not for you. Although it does not take complicated tech work it is definitely not a drop in and go item. Don't know why G & P get such high reviews as this is the second out of two to fail in the same exact way
