Dont regret getting the ARMS 40A2.

I chose the 40A2 over the 40 for my AR-15 Sights. When I asked around, most people suggested ARMS. Of the ones that had the 40, some said their only regret was not getting the 40A2.

The best carbine BUIS sight

If you want a quality built back up sight for an AR carbine, this is one of... if not the best. It is designed with the spring-loaded pup up style. The overall quality of every component is excellent. I will be buying another in the future. They (A.R.M.S.) also make a front sight to pair with this one as well.
