The Hawke Flip-Up Cover – Objective (40mm), model 61003, is a precision-engineered optical accessory designed to shield non-adjustable objective rifle lenses from environmental debris, dust, moisture, and impact. Built from high-grade, rust-resistant machined aluminium with a matte black finish, this cover installs via direct screw-in attachment directly into the internal objective threads of compatible optics. It features a spring-assisted, one-touch flip mechanism that supports rapid, single-handed deployment in the field, while providing multi-directional rotational positioning so shooters can index the lid's opening angle to clear rifle bolts or auxiliary hardware.

Key Features

• Screw-In Thread Mounting: Direct screw-in attachment threads directly into the objective housing for secure, tool-free installation that will not slip under firearm or spring-piston airgun recoil.
• Single-Handed Deployment: Integrated spring-assisted opening allows fast, one-touch access to the objective glass for quick target acquisition.
• Customisable Rotational Orientation: Fully indexable design allows the cover to be positioned to flip open upward, downward, left, or right to accommodate rifle clearances.
• Aluminium Construction: High-grade machined aluminium body resists UV exposure, high temperatures, and physical impacts without cracking or warping.

Specifications

• Lens Fitment: 40mm objective lens
• Mounting Interface: Internal objective screw thread (tool-free installation)
• Material: High-grade aluminium
• Finish: Matte black
• Operation: Mechanical spring-assist, one-touch flip-open
• Power Requirements: None (purely mechanical)
• Optic Compatibility: Post-2015 Hawke non-AO riflescopes (including Vantage 3-9x40, Vantage 4-12x40, Vantage IR 40mm, and Airmax 30 SF Compact 3-12x40)

Who is the Hawke Flip-Up Cover Objective 40mm for?

• Pest control shooters — Requires the direct screw-in thread mounting designed specifically for post-2015 Hawke 40mm non-AO rifle scope objective bells, ensuring the flip cover remains firmly seated under repeated recoil without shifting.
• Stalk hunters navigating dense brush — Protects the exposed 40mm objective lens from scratches and debris while providing spring-assisted, single-handed deployment for immediate target acquisition.

Less suitable for: Hawke scopes equipped with an Adjustable Objective (AO) mechanism, pre-2015 Hawke optics, Hawke Frontier 30 / Frontier 30 SF models, and Hawke XB/XB1 crossbow optics; shooters using 40mm AO scopes require a dedicated AO-threaded flip cover (model 61004) to match the distinct thread pitch and outer bell dimensions.
