I finally found a good deal on the scope I have been looking for for three months so I am selling this Mark 4 to fund the new one.
The scope is in excellent condition and shows very little sign of use...rings marks aren't even visible. It has been set back to it's optical center and is ready to zero in.
As stated, it has the M1 turrets (1/4 MOA clicks) and Mil Dot reticle. It comes with the original box (matching serial number) and paperwork and the Butler Creek flip-ups were never used (I used the Alumina version). $975 shipped.
