The Leupold Mark 4 Anti-Reflection Device (ARD) 30mm (MPN: 62870, Model: LE62870) is a specialized optical accessory engineered to eliminate target-side lens glare and reflection. In the high-UV, high-glare conditions of the Australian outback, direct sunlight striking a riflescope's objective lens can create a bright flash, immediately alerting game or revealing a shooter's position. This device utilises a high-durability, matte black polymer housing to secure a precision-engineered Tenebraex honeycomb baffle grid. This grid acts as a physical barrier to angled sunlight, allowing direct light to pass straight through to the shooter’s eye without distorting or dimming the sight picture. Beyond reflection control, the low-profile unit serves as a protective barrier shield for the front glass element against dust, grit, and scratching in harsh field environments.

Key Features:

• Tenebraex Honeycomb Grid: Features a dense network of microscopic cells that block off-axis light from striking the lens, stopping glint and glare while maintaining high light transmission.
• Direct Threaded Attachment: Screws directly into the objective lens threads of compatible optics for a secure, low-profile fit that does not add bulk to the rifle setup.
• Physical Lens Shielding: Provides mechanical protection for expensive front glass elements against airborne debris, dust, and scrub scratches during transport and field use.
• Rugged Polymer Construction: Built from a durable, lightweight polymer finished in matte black to eliminate any secondary reflections from the housing itself.
• All-Weather Performance: Completely mechanical design with no electronic components, ensuring reliable operation in extreme Australian temperatures and wet conditions.

Technical Specifications:

• Manufacturer Part Number (MPN): 62870 (also referenced as LE62870)
• Housing Material: High-durability polymer
• Finish: Matte Black
• Internal Grid Technology: Tenebraex honeycomb baffle
• Optic Compatibility: Designed specifically for post-2004 manufactured Leupold riflescopes. It fits scopes featuring a 24mm objective lens, as well as 20mm objective scopes built on 30mm maintubes.
• Sizing Note: While designated as "30mm" by Leupold (referring to the thread and outer housing size compatible with 30mm-maintube scopes), this unit is sized for 20mm and 24mm objective lenses and does not fit standard 30mm objective lenses.
• Power Requirements: None (fully mechanical, non-electronic accessory requiring no SAA or RCM electrical certifications).

Who It Is For:

• Tactical Marksmen: Precision shooters who require absolute concealment and must eliminate any potential lens flash that could compromise their position.
• Australian Varmint and Big Game Hunters: Ideal for hunters operating in the open, high-glare terrains of Australia where bright sunlight can cause severe lens flare or spook prey.
• Outdoor Sportsmen: Owners of compatible Leupold riflescopes looking to safeguard their optical investment from dust, sand, and physical damage when navigating dense scrub and rugged terrain.
