I just got a new 512 eotech and mounted it on a full size AR. I sighted it in at 50 yrds on a 3" circle target. Shots are staying in the 3"at 50 yrds and i am still able to hit steel plates at 200 yrds. Was this a good range at sighting in the eotech. Its mainly for 3-gun competition and the ranges seem to be anywhere from 50yrds out to about 250 yrds. Its a match HBAR, and i know its accuracy can be much better than this, but i do have a 3X9 variable for longer ranges.
