Ok so lets be honest, All this for $80 Bucks is a STEAL. no doubt about it, i have seen just the gearbox shell go for about $60, so to get the rest for another 20 was great, including some of the external components.

The Good,
The gearbox with the 8mm bearings is very nice, the spring guide is all metal, the cylinder is very nice and gets great compression. the cylinder head and air nozzle are both metal and get great compression. although i did not need them, the external components such as the charging handle and the selector switch was a nice bonus. I don't know what the FPS was originally, but i popped a Systema M120 spring and it shot 435FPS!

The Not so Good.
now I have not personally had a problem with the G&P White Piston, i have heard of them being defective and lead to premature death, needless to say i replaced right away with the G&P Blue SR 25 Piston. i have used a set of G&P gears for 4 years and one of them failed, the axle snapped, i have heard of this happening with G&P gears. the wiring harness did not have the usual terminals to connect it to a motor, but that was easily fixed with a soldering iron and some elbow grease.

This Gearbox fits great in a G&P Body and shoots great with the G&P Hop Up.
Overall I am extremely happy with this purchase.
