I had an issue with a 1 X 4 IOR scope that I had used for 3 gun for 6 or 7 years. The magnification ring was binding somewhere around 2 power. I called Val at IOR and he asked me to send it back so he could have a look at it. I was contacted today and informed that an upgraded replacement was on the way. Turnaround time according to the tracking number in less than 2 weeks. Thanks IOR!!
