To me, if tactical cool stuff makes you hit your target better then so be it. For me, I'm old school. I don't want to rely on some technological whata majiggy thing to help me shoot better. I want to rely on my shooting skill ability to hit what I am shooting at. Skills can always be honed and improved. When SHTF you can not always say time out, my tactical cool stuff broke and I need to replace it to be any good. JMO.
