lol well, idk there might be a scope skin for each gun somewhere in all the files, and if you could locate which is which you may be able to change the skins, but the fact that the two scopes have different animation (m4 is wobbles when you move, and awm has lines that retract showing the accuracy) probably puts them in two totally different catagories. in the end, i think you may be able to find the scope skins somewhere, it's just the animation for them that you may have trouble modifying.
