I am listing this scope for a friend since he is kind of computer illiterate. Here is one for all you long range shooters! The scope is a fixed 24X Leupold Mark 4 M1-16x40mm 40mm Objective 30mm Tube Scope is in like new condition. It was mounted on a .50 BMG, but was only shot a few times. No ring marks on the tube. The scope was purchased new from Premeir Reticles, which is who did the power upgrade from 16x to 24x. They also changed the reticle from Duplex to the CPC Leupold reticle. The scope is warranted for life through Premeir Reticle, although the original Leupold warranty card is included. Scope goes for almost $1600 new, without the upgrades. He is looking to get $1000 for. Reasonable offers will be considered.
