Ordered one of these for my M&P15 to replace my enormous Eotech 555. Anyone have experience with one, good or bad? Reviews seemed very satisfied, with the caveat that one in a hundred didn't work at all and had to be returned for replacement.
Since I'm not kicking doors with CAG or DEVGRU, I thought the SIG would be a good option for the price.
