Leupold Mark 4 ER/T 6.5-20x50mm Rifle Scope

Leupold Mark 4 ER/T Rifle Scope: Precision Engineered for Demanding Shooters

The Mark 4 ER/T represents the pinnacle of long-range riflescope design. Built for shooters who demand nothing less than absolute reliability and optical excellence, this scope combines time-tested engineering with advanced lens technology.

Optical Performance

First-Focal Plane Reticle — The H-58 reticle sits in the first focal plane, meaning it scales proportionally with magnification. This design allows precise holdover calculations at any power setting, essential for long-range precision shooting.

Premium Lens Coatings — DiamondCoat 2 treatment maximizes light transmission while providing exceptional abrasion resistance. The Extended Twilight Lens System optimizes color rendition and low-light performance, giving you a bright, clear sight picture from dawn to dusk.

Generous Eye Box — A forgiving eye position means faster target acquisition and more comfortable shooting sessions, whether you're competing or hunting.

Mechanical Reliability

• 34mm Main Tube — Larger than standard 30mm tubes, providing additional elevation and windage adjustment range for extreme-distance shooting
• 3:1 Zoom Ratio — Crystal-clear image quality across the entire magnification range from 6.5x to 20x
• Lockable Super Fast-Focus Eyepiece — Rapid focus adjustment with positive locking mechanism
• Side Focus — Parallax adjustment for precise focus at any distance
• Twin-Bias Spring Erector System — Maintains optical alignment and durability through years of use

Environmental Sealing

Fully waterproof and fog-proof construction with Guard-Ion rain shedding coating ensures performance in harsh conditions. Blackened lens edges reduce glint and internal reflections.

Note: This is a blemished unit, which may have minor cosmetic imperfections. Optical and mechanical function are uncompromised.
