Before I went to the range I took some pictures in the backyard of how crisp the reticle looked. Even when the reticle was in the corner of the glass it still projected a full reticle.
Took it to the 100 yard range and had some pretty good results. I was using a Tavor 18.5'' barrel and using 62 grain fmj bullets. At a 100 yards I was pretty impressed. This product takes a CR2 battery and it has an auto 5 min shutoff. once you bump it or bring the rifle back up after 5 minutes the unit turns back on in an instant. I found that to be a nice feature. This also has a locking QD mount where you have to manually push a lever to get the QD to disengage. I will be taking this unit out again in the near future to see how it holds it zero after I take it off the rifle. I will post more info if anyone is interested.
