Leupold Mark 3HD 4-12x40mm Riflescope TMR Illuminated Reticle

The Leupold Mark 3HD 4-12x40mm delivers precision optics engineered for tactical applications and long-range shooting. This riflescope combines proven Leupold glass quality with modern illuminated reticle technology in a robust 30mm tube platform.

What Makes This Different

The Mark 3HD features Leupold's Advanced Optical System with fully multi-coated lenses that transmit 92% of available light for superior clarity in low-light conditions. The 30mm main tube provides 25% more internal adjustment range compared to standard 1-inch tubes, while the illuminated FireDot TMR reticle offers precise holdover points for extended range shooting. Built to withstand recoil forces up to .375 H&H Magnum, this optic exceeds military durability standards.

Key Features

• 4-12x magnification range with 40mm objective lens for versatile shooting applications
• Illuminated FireDot TMR reticle with 11 brightness settings plus off positions
• 30mm aircraft-grade aluminum tube with matte black hard anodized finish
• Waterproof to 1 meter depth and nitrogen-filled for fog-proof performance
• Side focus parallax adjustment from 50 yards to infinity
• 1/4 MOA click adjustments with audible and tactile feedback
• Compatible with standard 30mm scope rings and Picatinny rail systems

Field testing demonstrates consistent tracking accuracy across the full adjustment range, maintaining zero through temperature extremes from -40°F to 140°F. The TMR reticle pattern provides precise aiming points for wind compensation and bullet drop compensation out to 800+ yards. Low-profile turrets resist accidental adjustment while remaining accessible for field corrections. The scope maintains optical clarity throughout the magnification range without edge distortion or chromatic aberration.
