Give 50 dollars for it if its that bad?
It is.
The gun came with a blown wiring harness. Fixed it to discover the gearbox was having trouble pulling the spring and ground to a halt. It needs a complete rebuild and possibly a motor. Could be a simple thing as expanded bushings or a bad motor. Either way, I don't have the time nor want to fix it. Either way it could cost you a new one to fix this one. So I highly suggest a tech with parts buy it.
It may be SPT.
Xavier, third time is the charm.
