Great value - Leapers UTG ACCU-SYNC Top Mounted Deployable Rear Sight

I’ve purchased several sets of these flip-up sights. Compared to other brands these sights work very well and they are very affordable. They’re made out of aluminum. Some other UTG flip-up sights are marked “made in U.S.A. but these are not. There’s other ones that are made here. I don’t see any difference in quality. The sight is click adjustable and has a small and large apertures for short or long distance shooting. Since these are just “back-up” sights they won’t be used often. I do prefer aluminum flip-up sights compared to polymer sights.
