I have a Nikon Buckmaster 3-9X40 that I am going to put on the Omega. I originally bought this for my Knight Bighorn, but I couldn't pass up the deal on the Omega for $169.00 at Walmart last night. I think with the 28" barrel, the Omega would be a better long distance gun than the Bighorn with the 22" barrel. Do you think I could use the low rings? They are what Leupold recommends on their mount selector. I would like to get the scope as close to the barrel as possible. Thanks again for the info.
