found out what the problem was, on closer inspection I noticed two little circles on the back of the upper and realized there is supposed to be 2 little tabs on the back of it that act as an anchor point so the gun doesn't pivot on the front pin.... well both of them are broken and now we need to squeeze the upper receiver every once in awhile so it grips the mech box and uses it as an anchor. Well needless to say Talraga is pissed and unless I can find a drill that'll fit just right so I can put new pins in it Talraga might have to buy a new body -.-'
