was looking at one yesterday in a store and it was priced at 499$...another customer remarked that I shouldn't mount it on a 308 because every time he fires his the sighting image blinks off...the guy behind the counter didn't seem to feel this was unusual???? Is this typical of these imported red dots???I see lots of reviews on youtube and most are on 223/7.62x39 class of arms but surely they must be able to stand more....could it be the larger heavier aaa battery moves enough in recoil to cut the power just for that split second....comments???
