Leupold Mark 3HD 3-9x40mm Rifle Scope Mil-Dot Reticle 30mm Tube

The Leupold Mark 3HD 3-9x40mm delivers precision optics engineered for tactical applications and long-range shooting. This scope combines Leupold's HD lens system with a robust 30mm main tube to provide exceptional clarity and reliable tracking across demanding conditions. Built to withstand recoil from magnum cartridges while maintaining zero, the Mark 3HD serves military, law enforcement, and civilian precision shooters who require unwavering optical performance.

What Makes This Different

The Mark 3HD incorporates Leupold's Twilight Max HD Light Management System, which increases usable light transmission by up to 5% compared to standard coatings. The 30mm tube provides 25% more internal adjustment range than traditional 1-inch tubes, allowing for extended-range shooting without external adjustment devices. The scope's aircraft-grade aluminum construction undergoes a proprietary hardening process that exceeds industry durability standards by 40%.

Key Features

• 3-9x magnification range with 40mm objective lens for versatile engagement distances
• Mil-Dot reticle system enables precise range estimation and holdover calculations
• 30mm main tube delivers 80 MOA of total elevation adjustment
• Twilight Max HD coating system maximizes light transmission in low-light conditions
• Waterproof to 1 meter depth and nitrogen-filled to prevent internal fogging
• Fast-focus eyepiece accommodates prescription glasses and varying eye relief
• Matte black finish reduces glare and provides corrosion resistance

Field testing demonstrates consistent tracking performance across temperature extremes from -40°F to +160°F. The scope maintains zero through 1,000+ rounds of .300 Winchester Magnum recoil testing. Competition shooters report reliable performance in precision rifle matches, while tactical operators utilize the Mil-Dot system for rapid range estimation in dynamic scenarios. The HD lens system provides clear target identification during dawn and dusk hunting conditions when standard optics struggle with light gathering.
