It's SUPPOSE to be compatible, but there are pretty good chances that a lot of the parts are poorly made and will not be. It will be cheaper to replace the entire mechbox, and the motor, probably with a JG set off of velocityarms lol. Even then, I would assume that the low-grade plastic will crack or break quite easily, and you may have to replace those as well, then you end up with one of those semi-rare cases where the only stock part on your gun is the screws in the pistol grip
