*EDIT*
Same idea as droc's idea.

Dont take the gun apart until you are positive on what the problem is. I had the exact same problem with my mp5 sd5 (which is practicly the same gun) and fixed it in 5 mins with the proper tools.

First off look for a little hole on the bottom of the pistol grip, second take an allen key that fits in the hole and adjust the screw thats inside the hole up or down (this will push the mortor gear so it is level with the gears in the mech box.

You gears on the mortor are not lineing up with the ones in your mechbox. Thats what's creating that horible sound.

Hope that helps
