I got this last week when I bought a demo scope from a local shop and I have no specific use for it at the moment. It fits a 34mm scope and is 0 MOA. I don't know much else about it so please google thee model for additional details. I did weigh it and it's exactly 9.0 ounces as advertised. Note that it did not include the leveling device. I'm looking to get $310 shipped OBO via paypal. I'll also accept other forms of payment is needed. Everywhere that I've looked has this listed new for $410.00. Please PM any questions.
