Intersting little sight. Kinda cheap...primitive is maybe a better word, but I have to say mine held up perfect throughout the time I had it. It was first mounted on a crosman 1322 pump airgun. It held up fine to the pumping and the sight held 100%. Never did care for the sighting in with this sight but once I got it on target it stayed there. Later I mounted it on a spring airgun of a bullpup design. I really didn't think the sightmark would hold up to the weird scope eating recoil that springers are known for, but once again it held up fine over 200-300 shots. I sold it with the airgun and so far as I know its still kickin. Never tried it on a powdergun but I wouldn't hesitate to try. Really like the 4 way reticule by the way, it was very cool. J
