Very well built compared to some less expensive ones I tried first.
Installed one each of theses on an AR556 and M&P15 Sport II to replace two cheaper carry handles I had initially purchased. Those had wobbly, imprecise sighting mechanisms.
These have well made, precise, sights. No "wobble" at all.
Wish I had done more research and held out for these first.
Very pleased. They look great on my AR15s.
Both my ARs are sighted in at 50 yards with the large aperture and hit on again at 200 yards with the small aperture using 55 grain FMJs (Win Q3131 and Fed XM193).
One comment not worth deducting a star for. In switching between the large and small apertures on both of mine, the mechanism is very stiff, and a little rough feeling. But maybe that's as it should be. They hold position well. Might smooth out with time.
