Well this isn't exactly my problem, it's talraga's but since I'm the guy he goes to too fix his guns and I'm only guessing on whats wrong I've decided to ask. The problem is the back end (part with forward assist) of the upper receiver has widened, causing the gun to wobble a little, I think it's because the CA receiver
which is only connected by the front pin causing a pivot point is allowing the mech box to bend out the upper receiver, so far I've minimized the wobble by simply taking the receiver apart and squeezed it until it bent inward a little bit but the wobble just won't go away 100%.
any help would be nice as this is a stumper for me... >.> also if I'm right on why this happened then I'll be so turned off by CA guns that I'm never gonna get one of my own..
for those of you who can't picture what 'm talking about, here is an actual picture of it, I just did this using photoshop it's not his gun, the problem is that the receiver is open along the red line.
