A few weeks ago I bought a GPO tac 15-45x65 spotter from Doug camralandny. I ended up messing up the bottom mounting screw hole which was all my fault. But I also had a terrible time getting it clear and focused with the reticle. I called GPO and spoke to Mike the president he replaced my unit no questions asked and had them quality check the new unit to make it was good to go. I was tight on time before the nightforce match and he got it shipped back in time. The new unit is very impressive glass wise and easy to focus. I thought I'd give them a shout out great product and one of the best customer service I've seen.
