"This gearbox is pretty good. I do have some issues.

built well
good quality
good fps (havent chronoed yet but it seems high)

doesnt fit well in a G&G raider body. It fits but doesnt act right
slow rof
fps might be too high

"Great gearbox for a quick swap out with whatever you have at the moment. If you have experience working with gearboxes, if you switch out the piston in this one, it'll make your life alot easier.

"This is a pretty good gearbox. The parts are decent quality and its is pretty easy to open up and work with. But.. There was almost no air seal in mine so I had to stretch out the O-ring on the piston head. After that, there was a decent air seal with the parts the gearbox came with. Another thing is the spring is pretty strong. After a little bit of messing with air seal its a pretty good gearbox.

"This gearbox worked fine, except my fps dropped to barely breaking 200 fps with it.... total waste of money

"This is a piece of junk. Piston had no seal on on it, dropped FPS. The leads were poop and snapped as I put them onto the motor. Save your money and buy something worth while.
