Good feedback from everyone! So, I count one first-person failure with an Aimpoint T/H-1, one partial failure observed with with an Eotech (batteries?). I also count a lot of "I like shooting with irons!". Agreed... brings back those retro Army A1/A2 memories for me.
Some of you gents mentioned "cheap insurance"... have you priced a set of Troy or KAC BUIS lately? That aint cheep! (which I guess is why I've gravitated toward pricey red-dots and plastic backup sights!).
Thanks again for the feedback and opinions.
