Tried to site my irons yesterday and found the process confusing. This was my first time ever shooting an AR so even my benchrest groups were unimpressive. I was centered but high and low. Had a 3 shot group over the bullseye and everything else was at 12 and 6(roughly 10 rounds total). Not sure if I was using the bench rest properly. I had a lot of trouble with the site picture my vision would get blurry and my front site wuld cover the majority of the target making it hard to be precise. Just looking for some recommendations and to hear some of your experiences.
