So i had an issue with a sightron scope i got last year. I had not shot this rifle much. I notices on last two trips out with it i could not get parallax to focus unless i lowered magnification. I sent it in for repair. Got is back one week later. I opened it up. There was no note, was just curious what they found wrong. Got to looking at it and they gave me a brand new scope!!!. Must have been an issue with it. This is first scope i have ever had to send in and i was completely happy. I do own other brands also but like the simplicity of these scopes and track good. Thanks sightron.
