Leupold keeps their successful tradition of delivering state of the art sport optics alive with persistent attention to detail, precision and quality. This American optics company, located in Portland, Oregon, pioneered the process of nitrogen purging to waterproof riflescopes in 1947. Since then and to this day Leupold continues to develop new technologies, and use advanced materials to push the envelope to produce some of the world's finest sport optics.
Military, special ops, and law enforcement tactics have changed dramatically in the last decade. The ubiquitous 3-9x40 or straight 4x & 6x sighting systems are now being eclipsed by high powered zoom riflescopes. Larger objectives are favored for their ability to gather light and deliver a brighter image. Precision shooters looking for greater magnification and a bright sight picture will find the 6.5-20x50 Mark 4 ER/T M1 Riflescope to be right on point. Like all of the Leupold Mark 4s this scope has the added windage and elevation adjustments made possible by the 30mm main tube. The large 50mm objective helps to deliver a brilliant sight picture, even under less than ideal lighting conditions. Leupold carefully matches each lens element in the optical stack so every scope delivers the best image possible, regardless of the ambient lighting situation. The powerful 6.5-20x configuration of this Mark 4 definitely lets you reach out to great distances. While the 6.5x magnification can most definitely be sighted while hand held, the 20x end of the zoom will be most effective when your bipod is deployed and solidly set onto a stable surface. When it's go-time, and 100 percent success is the only option, you can count on Leupold to deliver the optical advantage you need for a victorious conclusion.
To use a riflescope with your firearm, you'll need a mounting base and mounting rings in addition to the scope itself. Bases attach to your firearm and rings attach to your scope. By affixing the scope mounted rings to the rifle mounted base you create a reliable accurate, and secure sighting system. Proper spacing of the rings, as well as the ring height should be considered to ensure a proper line of sight can be established. This will maximize the value of your investment, and enhance your shooting experience. It should be noted that in many mounting applications, a professional gunsmith's skills will be needed for proper installation.
Absolutely waterproof and fogproof
30mm Diameter main tube milled from a single piece of 6061-T6 aluminum
Target style M1 knobs with 1/4 MOA precision adjustments are easy to read and adjust under difficult conditions
Side focus parallax adjustment for fast, easy parallax focusing from 75 yards to infinity, from any shooting position
Index Matched Lens System
Proprietary coating materials are individually specified for each lens surface within the riflescope, based on its refractive index, placement, and function. These coatings are also matched to each lens' glass type and multi-layered to minimize reflections and maximize light transmission. The result is unparalleled brightness and clarity.
TMR Reticle in First Focal Plane
The Tactical Milling Reticle expands upon military Mil-Dot type reticles with variable sized and spaced tic marks for increased ranging precision. Calculations are based on the Mil-Dot ranging system, with the added advantage of having 1/2 mil spaced hash marks & 0.20 mil spaced tick marks near the posts for greater accuracy and versatility
This scope has the reticle positioned in the first focal plane. The reticle is magnified
along with the image, so you can estimate range at any magnification setting.
