I found this ad for a scope. Does this have the M1 Knobs. I havent owned a Mark 4 scope before. Pros or cons to this scope. Thanks (I have a Leupold Mark 4 Long Range Precision 4.5 to 14, 30mm, mil dot scope for sale. I purchased new about a year ago. It has been mounted once and been out to the range twice. No imperfections or blemishes. The round count is at 67 on this set up. This scope sells new for $879...I want $575 for the scope with the box and a set of Leupold standard 30mm rings).
