I have a Varmint 4-12 SF that had problems. I had never taken it off 12x since new and when I tried to turn it to 4x it was gritty while turning the power ring. It also never appeared to be a full 12x compared to my other scopes. On the plus the scope has been clear and very repeatable adjustments for a $170 airgun scope. I emailed Hawke Sunday at 5 PM and received a call on Monday about 9am.Even though I didn’t have the receipt they said to return it.In the meantime I found out the tension screw on the ring had slipped off the internal “keyway” and when I found this I was able to get it working an all is well.
So feel confident buying their products.
