I have a nice Mark 4 up for sale. No ring marks, glass is great and it tracks excellent. It has been on a safe queen rifle for the past 9 months and I am trying to free up funds for a new project. The BC flip-ups are included. I am pretty sure I have the box for it but after our garage cleanout this summer, it's not where it used to be. I will continue to search. This will be listed on multiple sites. Please post an "I'll take it" followed by PM. Thanks for looking.
