Leupold’s® Mark 4® 8.5-25x50mm Extended Range/Tactical M1 Front Focal riflescope is designed to let you take advantage of the reach and power of today's high-power hunting and extreme long-range target rifles.

Every feature was put in place for one purpose: to help you get the maximum advantage from your high-power rifle, whether you're hunting or in competition.
