"Just a heads up to the gun techs out there, this gearbox will not fit in a king arms upper receiver. Other than that it is a great gearbox haven't had any issues other than the wiring. Swap that out and you have a top of the line gearbox
"Amazing gearbox. Very solid and durable. I've had my KWA M4 RIS for a year now with tons of BB's put through. My only issue is the fact that I was a noob about the gun and kept the spring under tension so now it shoots 360 instead of the previous 400. It's my fault though.
If you have a compatible gun, this gearbox is amazing. I would totally reccomend. The whole design is slightly proprietary but still not a big deal because upgrading really isn't needed.
