Solid build, easy to set up and sight in. I have four set of these sights and work as designed.

I’m old enough to have used iron peep sights in my high school days on the rifle team and am very familiar with the accuracy that this style sight is capable of delivering.
The Dioptic rear aperture makes precisely centering the front sight post very easy and the tritium inserts extend the usability of these sights into conditions of failing daylight well beyond those sights without this feature.
Buy once, cry once, own the best.
