Just bought and mounted one to an older Dianna spring gun to give to my son. Shot a few rounds to sight it in an holy sh*t, this is as good as my Hawkws. Just bought a Hawke aimax for mt new TX200 and now wonder if I could have saved because nothing cheap about this scope. Will see how it lasts but so far for the price this is a real winner. Anyone else with positive or otherwise opinion ?
