Leupold Deploys Battlefield Upgrades for Mark 4 Riflescopes

BEAVERTON,OR – Leupold's Tactical Optics Division has upgraded its Mark 4 Extended Range/Tactical (ER/T), Long Range/Tactical (LR/T) and Mid Range/Tactical (MR/T) riflescopes to give American warfighters and snipers an even greater edge on the modern battlefield. The upgrades also offer numerous optical advantages for hunters, competition shooters and other civilian shooting enthusiasts.

Primary upgrades include Leupold's Xtended Twilight Lens System, as well as options such as M5 0.1 mil windage and elevation adjustment dials, Horus reticles, front focal plane reticles and third-generation illuminated reticles. Selected options can be retrofitted for existing Mark 4 riflescopes, depending on model.

"These upgrades further enhance our field-proven line of Mark 4 riflescopes," said Kevin Trepa, Leupold's vice president of tactical sales and marketing. "Our mission to serve the unique needs of American warfighters and demanding civilian shooters continues as we develop precision optics to help them take maximum advantage of the reach and power of their rifles."


New ER/T, LR/T and MR/T models feature the Xtended Twilight Lens System – Leupold's best lens coating technology for low-light conditions. The system utilizes Leupold's index matched glass with lens coatings designed to optimize the transmission of low-light wavelengths. As a result, shooters receive a crisper, brighter sight picture in dim light than ever before.


Following are key features of the available options:

  • M5 windage and elevation adjustment dials have audible, tactile 1/10 (0.1) milliradian clicks to match range-estimating, mil-based reticle options. This allows fast and easy correction in the field, resulting in greater shooting precision.
  • Horus reticles are mil-based and employ an advanced two-dimensional grid system that helps enhance both accuracy and ease of use. The fine grid marks do not obscure targets and thus allow rapid engagement, while the intuitive design can dramatically reduce training time. Horus reticle options include the H26, H27, H36, H37 and H58.
  • Front focal plane reticles allow the operator to use the scope on any magnification while retaining the exact spacing of range-estimating reticle features (the reticle magnifies with the image). Consequently, the operator can accurately estimate range and calculate holdovers at all power settings.
  • Leupold's third-generation illuminated riflescope reticles advance the technology with an array of features designed to provide a user-friendly, intuitive system for fast target acquisition in tactical low-light situations. Third-generation illumination offers a 15 percent brighter reticle, eight different intensity settings (two compatible with night-vision equipment) and redesigned control dials to enhance ease of use.

While no single Mark 4 riflescope can be fitted with all the upgrade options, numerous variations exist and most models are capable of accepting multiple upgrades. To determine specific options available for particular scopes, contact Leupold Tactical Optics at 1-800-LEUPOLD.

Ready for deployment, Mark 4 ER/T, LR/T and MR/T riflescopes are waterproof, fog proof and shock proof. A 30mm maintube provides exceptional strength and allows for a wide range of windage and elevation adjustment. Exhaustive testing in the factory and field ensures durability. Flip-open lens covers are standard issue. Each scope comes in a matte black finish and is covered by the company's Tactical Optics Warranty.
