I have a Mark 4 "M3" 3.5x10 Leupold MOA scope. These were designed for the military and LE. It has been sitting for years and I am sure I won't be using it anymore. I am 76 and cutting down on things I won't or don't use. It comes with 4 knobs but two of them were painted over and scribed with my data for my 260s. The 300WM and the 30-06 knobs are still stock. The 30-06 knob matches the modern 308 ammo pretty damn close. Has the mil dot reticle in it. Scope is in great shape but does have ring marks where the rings came together. Would take $600 plus shipping if anyone is interested. No papers or box. Thanks guys!!
