Issue Description:
When you change the sight adjustment on the static M60 or PKM, they don't change correctly. The rear sight will move up and down, but will hold alignment for the rear sight position of the initial setting of 100m on the PKM and 300m on the M60. Thus, the player's view is blocked and the point of aim isn't adjusted.
