Ok yes it performs better than most low quality gearboxes but that's how it is with JG and most other low quality companies. they tune their gearboxes to perform like G&G and KWA but they use cheap parts that break. this gearbox only had about 3000 rounds when the piston stripped and the gun started to sound like someone poured sand in the gearbox. My brothers have owned 3 different JG guns and all of them had lots of problems. Our JG s-system had major feeding issues and wire issues and we ended up trading it for a new JG m16. this gun (not even kidding) almost started on fire. it stopped shooting, and when we opened up the stock to check the fuse smoke was pouring out! after that was fixed the gearbox shell cracked and it was scrapped and sold in parts. now our JG m4 had this gearbox. besides this gearbox breaking with very minimal use it also had hopup issues. Just dont waste your time with anything that is JG. Get a G4 its cheaper and it has G&Gs wonderful internals (but i think the G4 gearboxes dont have bearings though). anyway, this gearbox is simply crap.
18rps with a 9.6v battery
its a great way to waste your time and money
sets a good example as to why nobody should use JG guns
broke after only 3000 shots
dont buy it.
