Re: Vortex Viper PST question
Maybe you should just buy one and see for yourself. I have a SFP 6-24X and have relegated it to rimfire duty. I sent in the original twice and the sent me a new one on the last trip. I now seem to be having a problem with a wandering zero, although I'm not going to attribute this to the scope until I can confirm it with a different scope.
Still, the scope does have nice glass and it seems to be built well. My biggest gripe is with the turret knobs. The adjustments are positive, but the detents seem small to me. They get inadvertently turned pretty easily. If I've been carrying the rifle slung for any length of time, I have to confirm that it's still set correctly before I shoot.
