Hi. Would you be willing to trade for a 6.5x20x44 Vortex Viper rifle scope. It has the Mill Dot recticle. I have only had it a few months and is very nice glass. It tracks perfectly and has no ring marks. Here is a link to the scope. Let me know. Thanks Dale Vortex Optics - Viper 6.5-20x44 PA Mil Dot Reticle
