Shaky A2 sight... how to fix ?

[Westicle]

well I got a used 11,5" upper and the a2 sight on it does not seem right, it turns far to easily and seems really loose in the mount.....

any suggestions ?? I allready ordered a new assembly from armalite but am wondering what the problem could be.

upper is a colt keyhole a2 upper.

Leave them alone, as long as they rest in the same position the slight tilt to the left make no difference...

it is not a tilt that the problem is , looking closer at it and a diagram it would appear as if the wheel itself is out of spec somehow..... it is not contacting the little ball bearing as it should. when shooting I noticed the sight was ratcheting itself down as well. was not holding position.....

talked to ryan at wolverine and ordered a whole new assembly, the upper is a parts upper so I am thinking the a2 is a cheap knockoff that got installed, definatly not colt quality.
