"Bought this for a JG AUG and it works flawlessly! I'm getting 350fps using .20s and out of a short CQB length barrel. Just what I needed!

"NOT high cycle getting about 18-19rps on 11.1lipo @ 310-328max FPS(stock) All 3 gears will have to be shimmed other than that looks decent for the price

"Received today and there are a few changes from the actual product received. The bushing are steel non bearing type which is good. It DOES NOT come with the top plate. The gears are okay. Cheap piston and cylinder head. Also this gearbox has some trouble fitting into an ASG AUG Commando XS, but I was able to make it fit okay with some work. Overall I'd give it 3/5 stars. The material of the shell seems good and the wires are durable and has clean solders. It could probably use a different motor. It also needed to be shimmed a bit. Also I will mention that the pressure sensitive trigger is a bit more tactile requiring a harder pull to retain full auto which can be good if you have semi only games.

Decent quality material
Qd spring
Comes with steel bushings not bearings.
Wasnt caked in grease.
Still managed to fit in asg body
Wires feel durable and not easily torn or damaged
Easy to upgrade

No top plate for dust cover
Cheap piston/ piston head/ cylinder head
Mild fitment issues
Motor soldered on

Recommendations - change piston, piston head, cylinder head immediately as they are cheap and had poor air seal. Replace grease it comes with. Reshim for sure.

Overall its decent for 80 bucks and looks like it will last a while.
