JG Complete Full Metal Lipo Ready Gearbox for G36 Series Airsoft AEG Rifles

"I bought this in 2017, if my memory serves it was jammed right out of the box, and made a horrible grinding sound after I had installed it in my JG. Pulled the gun out of storage recently, took it out of the gun, hooked it up to the battery through the wiring, and bam, it full autoed the moment I put it into semi. I had noticed the piston was stuck halfway back earlier and it was now back where it should be. Works like normal now, 10/10 gearbox would do it again.

"Just received this gearbox last week. It is absolutely high quality, and has a nice heft to it. I dont have a chrono, but i can say in comparison to my g&p gearboxes and m120 spring combinations, it can hold its own and compete for fps and effective feet. Make sure you order the separate motor cage. im running a matrix turbo 3000 short type, and the rps is probably around 18/19 on a 9.6v. It is Lipo ready, which is a bonus and completely upgradeable when necessary.

"Gear Box is amazing worth buying it. shoots about 400-450 FPS the selector plate was bent so save your old one. That was my Only problem.

Pros:
Fires perfect
400-450 FPS
great structure

Cons:
Selector plate

"I bought this to upgrade a destroyed gearbox in a G36 I received. The Trigger Shuttle in the new gearbox broke and the Cutoff lever was messed up. Out of the Box is it low quality and if you are willing to buy some extra parts and fix it up, it might be worth the cost.
