wobbly full stock
 

Hey i was wondering if someone could help me here, i just picked up a G&G GR16 and the full stock has become considerably wobbly. Is there any way to tighten it at all? Thanks for the help in advance.

... pull off the cap for the battery compartment, look inside there should be a screw up at the top ... it's what holds the stock to the gun ... tighten as needed...
