I just received my viper 6.5-20x44 last week that i ordered from Doug. Scope appears to be a very well made. Power ring turns nice and smooth. Very clear and crisp optics. I have a leupold vx-3 and i would say it is ever bit as clear if not clearer then the leupold. Its not quit as clear as my zeiss but for 250.00 i didn't expect it to be. The side focus works excellent as dose the fast focus eye piece. I really like the resettable zero on the turret. No tools needed just lift it up and turn to zero. For the money im very happy with the scope. I would honestly say you get way more scope for the money spent. I haven't mounted it and shot with it yet but i don't expect any surprises. I done quit a bit of research on the viper before Doug put the sale on them. Once that sale hit it was a sealed deal for me. And Doug don't mess around with getting them out to ya. He ships super fast thanks Doug for great service. You have my optics business.
