I've shot some pretty decent groups at the range out to 200-300 yards coming pretty close to what I can do with opitcs. In good light. Looking at a black aiming point that jumps out against a white background. But in a heavy canopy, 5 minutes into legal shooting time which is still 25 minutes till sunup those sights get lost on the brownish gray hide of a buck at even 30 yards. I'll stick with my scopes for hunting. But enjoy playing with irons at the range occasionally.
