I have a Bushmaster A3 with my Eotech rev.F mounted on a YHM riser. I am using a GG&G A2 style BUIS.
When I look through the peep hole of the BUIS, the Eotech blocks part of the bottom of the peep hole circle. Is it suppose to do this? Does anyone else have experience with this type of set up that can help with any information? Thanks!
