The Leupold Mark 4 HAMR is without a doubt one of the toughest scopes on the market. HAMR stands for High Accuracy Multi-Range Riflescope, and it features a seriously rugged construction in a compact design. The Mark 4 HAMR Riflescopes are best at mid-range distances and work in all lighting conditions, from bright daylight to night. They are also designed to work with Leupold's Deltapoint Reflex Sight for unprecedented target acquisition. All Leupold Mark 4 include free shipping and are covered by Leupold's Golden Ring Lifetime Guarantee, so if the scope doesn't perform like it is supposed to, they will either fix it or replace it to make things right.Receive FREE Ground Shipping on all orders over $39.99.
