please help me!

i got a mp5 and i wuz wondering if someone can help me. i got a new battery and in doesnt fit in the foregrip. so i decided to go with a full stock. now i need someone to tell me or show me how to rewire the battery so i can put it in the full stock.

btw its a crosman mp5 but works the same as a JG.

If your not experienced taking apart gearboxes and such I wouldn't recommend it. I'm not sure about the Crossman MP5 but MP5's usually have a V2 gearbox. Look here Mechbox.com | Airsoft repair and upgrades » Blog Archive » Rewiring version 2 mechbox

All I did was modify my foregrip to fit a 9.6.

Once you pop the gun open, there should be a connector at the back of the gearbox and an extension wire running to the front of the gun.

Simply move that extension to the stock.
