The Hawke Sunshade – Objective (40mm AO) (MPN 62004) is a dedicated optical accessory designed to screw directly into the objective bell of compatible Hawke riflescopes. Measuring 4 inches (100 mm) in length and weighing approximately 40 g, this anodised matte black aluminium tube acts as a physical barrier against stray light, lens flare, and internal optical reflections when viewing targets toward low-angle sunlight, over water, or across bright paddocks. In addition to improving contrast, the extended tube creates a standoff distance that shields the objective lens from direct impacts, field debris, and rain.

Key Features

• Glare and Flare Suppression: Extends the objective bell by 4 inches to block off-axis ambient light, eliminating washed-out sight pictures and maintaining target contrast in direct sunlight.
• Dual-Ended Threading: Features a rear male thread to mate with the scope objective and a front female thread that permits stacking multiple shades or installing compatible Hawke metal flip-up lens covers.
• Objective Lens Protection: Provides a rigid aluminium standoff that prevents branches, dust, and moisture from contacting the front glass element during field use.
• Lightweight Construction: Weighs approximately 40 g, minimising balance shifts and front-end mass on the host rifle platform.

Who is the Hawke 40mm AO Sunshade for?

• Varmint hunters shooting in high-ambient light open paddocks — Requires a 4-inch (100 mm) glare-reducing barrier on a 40 mm Adjustable Objective scope to prevent low-angle sun glare from washing out small, distant targets across exposed terrain.
• Precision target shooters operating in bright daytime conditions — Benefits from an approximately 40 g matte black aluminium tube that fits 40 mm AO bells to eliminate internal optical reflections and improve reticle clarity without substantially altering rifle balance.

Less suitable for: Applications where adding 50 mm to 100 mm of tube length compromises barrel clearance or snag-free portability in dense scrub (where an ultra-low-profile 9 mm honeycomb sunshade is preferred), or scopes with non-AO bells or differing diameters such as 32 mm, 44 mm, 50 mm, and 56 mm (which require dedicated, model-specific diameter sunshades).
