I wanted a set of flip up iron sight and fount A.R.M.S. sights. After installing them, I had the opportunity to go to make a quick trip to the range.
At 25 yards the sight were almost right at target center. I made some adjustments and the groups were great.
I moved to 50 yards and the groups were again very close. I made adjustments and then shot very good groups.
I am very pleased with these sights.
