My JG Mp5 was only problems from the start (itnernally). Even after replacing all the internals with a reinforced gearbox, the gearbox broke thanks to a metal body to tight.
After spending a lot of money and getting a new gearbox, it was tested and found no problem then sold.
Pain in the ass also to disassemble!
