I just received a new Bushmaster with A2 sights and noticed that the rear sight is off center and has about 1/4" of play in it when set at the 8/3 mark. It a spring loaded tension type of play so if I push the side of it and release, it always returns to its original, somewhat off-center position i.e. its not moving on its own when simply I move or shake the rifle. Additionally, when I dial it up, say 5+ clicks from 8/3 it cams clockwise and into the back of the carry handle and is perfectly flush. My questions are: Is it normal for it to be slightly off center? And, as it cams up, and flush to the carry handle, does it throw off my windagage at the longer distances?
Thanks for the help.
