"I love this thing. I dropped an aluminum SHS air nozzle in there and run it with my ASG boost motor. Boy does this thing deliver on speed and power! I recommend this gearbox to all of my buddies looking to drop a QSC gearbox into there guns.

"Works well for the project I used it on. QC Spring is ok for replaceing the spring even if you have to break down the gun to do it. Micro Trigger switch is awesome and that should be in every AEG Gearbox in my opinion.

"It's a vert good start. Well shimd And short triggeraction. But the piston, pistonhead, cylinderhead And airnozzel should be changed. The cylinder could also use a upgrade, but works Ok. I use this gearbox in all my AEG's. Love the quick spring change!
