Does anyone know how to dismantle the CYMK MP5J? The stock for some reason will not lock at either open or closed positions and so we are attempting to repair it.
take off the hand guard and the front end off then take the barrel off theres a clip with 3 scres holding it in then on the right side of the gun theres 2 scres holding the grip on take those off then theres a scres on the left side after you take off the grip in the back and 1 by the mag relese. then just take it apart.
