The LEUPOLD Mark-4 ER/T M5 6.5-20x50 Rifle Scope, Front Focal H37 Reticle (110087) is designed to let you take advantage of the reach and power of today's high-power hunting and extreme long-range target rifles. The M5 scopes' mil based adjustments complement the mil based reticles to make long range shot placement quicker and easier. Like all Leupold Mark 4 Optics, the ER/Ts deliver superior clarity and a generous range of windage and elevation adjustment for the accuracy and precision you demand at extreme distances.
The Xtended Twilight Lens System optimizes the transmission of low-light wavelengths, so you see the details of low-light scenes in greater, brighter detail than with any other riflescope available. Leupold engineers specify different coating materials for each lens surface in the riflescope, based on the lens' index of refraction, placement and function, layering each coating to eliminate reflections and maximize light transmission.
The H-37 reticle is an optically precise reticle which has a uniform grid etched on glass. The optically ergonomic design and layout of the reticle features a built-in rangefinder to provide the rifleman a clear picture and numeric information about the target.
This reticle is highly recommended for extreme-range shooters. Its central targeting grid is higher in the field of view, allowing more grid to be used at increased magnification. Thus, the H-37 can accommodate longer-range cartridges without requiring sloped bases.
Every feature was put in place for one purpose: to help you get the maximum advantage from your rifle, whether you're hunting or in competition. Outstanding accuracy, legendary ruggedness, and absolute waterproof integrity. All Leupold optics offer performance that makes them equally at home in hunting or tactical environments.
Other features for the Leupold mark 4 ER/T M5 SF Rifle Scope include: 30mm maintube; elevation adjustment dials with audible, tactile 1/10-MIL clicks; 100-MOA each of windage and elevation adjustment range.
