I used one several years ago. I don’t recall any quality issues with the iron sight or the attachment method. Only reason I ditched was due to me not liking A2 sights
Thanks! I’m glad to hear of no quality issues for you. As far as (not) liking A2 sights, I carried an M16A1 for over ten years before we got the A2 and I thought the A2 sights were the greatest thing since sliced bread - to each, his own.
I use one on my duty rifle and have for years. I have had no issues with movement or quality. Thousands of rounds and lots of training. I have one of the first ones on my duty rifle and the most recent version on my HD gun. The older ones only had one mounting slot for the EOtech where the new ones have multiple. They work well for me, however I haven’t found much love for RRA or EOtech here. There are a lot more options out there. When I got my rifle there wasn’t as many sight/mount companies out as there is now.
