Is your motor plated screwed on tightly? Some times if its not, the motor looses contact with the gearbox.

Start by taking an allen key to the bottom of the grip and adjust your motor height.

iv just taken the gear box apart and found all the gears are metal and fine but the white plastic bit that the spring pushes is worn away. where can i get one of those and how much will it be. also im having problems trying to get the gear box back together.

youre talking about the piston... get a new piston http://www.airsoftparts.ca/store2/in...oducts_id=1368

and go to mechbox.com for help on getting the v.2 box together

All MP5 expect the MP5K are V2.

The MP5K is a V3

is your old gear box front or rear wired?
because the one in the ebay picture is rear wired
