Will this flip-up cover fit my Hawke Sidewinder 4-16x50 riflescope?

Yes, this model 61009 is specifically engineered to fit Hawke scopes featuring a standard 50mm objective lens with internal threading, including matching models like the Hawke Sidewinder 4-16x50 FFP. However, please note it does not fit Hawke Adjustable Objective (AO) scopes or non-threaded models.

How does the cover attach to the scope, and can I adjust the opening direction?

The cover features a direct thread-in mount that screws securely into the front objective housing of compatible Hawke scopes. It also incorporates a 360-degree rotational internal locking mechanism, allowing you to orient the lid to open upwards, sideways, or downwards depending on your preference and turret clearance.

How durable is the construction for rough outback hunting conditions?

Unlike generic plastic or rubber caps that can crack in extreme cold or degrade under harsh UV exposure, this cover is crafted from high-grade, precision-machined aluminium. It is built to withstand heavy recoil forces across centre-fire calibres and provides robust physical protection against dust, mud, and rain during multi-day bush trips.

Does this mechanical accessory require any Australian electrical certifications for use?

No, as a purely mechanical optical accessory with no electronic components or power requirements, it does not need 240V compatibility, SAA approval, or an RCM certification. It is fully compliant for commercial sale and consumer ownership across all Australian states and territories.

50mm Flip Up Cover - Hawke 61009

The Hawke Flip-Up Cover – Objective (50mm) (Model 61009) is a precision-engineered optical accessory designed to shield the front objective lens of compatible riflescopes from rain, dust, mud, and physical impact. Constructed from high-grade, precision-machined aluminium, this cover secures via a direct thread-in mount to provide a rigid, recoil-resistant barrier for standard 50mm non-AO Hawke riflescopes across rimfire, centre-fire, and springer airgun calibres.

Key Features

Direct Thread-In Attachment: Screws directly into the internal threads of compatible 50mm objective lens housings, ensuring a secure fit that resists high recoil and field movement.
360-Degree Rotational Positioning: Features an integrated internal locking mechanism that allows the user to rotate and lock the cap to open in any direction, preventing interference with rifle barrels, actions, or turrets.
Machined Aluminium Construction: Built from durable aluminium to prevent cracking, distortion, and wear in demanding outdoor conditions compared to standard plastic or rubber friction caps.
Tactile One-Handed Operation: Equipped with opening tabs for fast, single-handed deployment in hunting and tactical situations.

Who is the Hawke Flip-Up Objective Cover 50mm for?

Hunters using standard Hawke optics — needing a dedicated riflescope flip-up objective cover that secures straight into the factory threads of non-AO 50mm objective lenses to shield glass from moisture and dirt during field carry.
Competitive shooters — requiring rapid one-handed target acquisition via tactile opening tabs positioned precisely around the 50mm objective without obscuring rifle action or turret visibility.

Less suitable for: Riflescopes featuring Adjustable Objective (AO) assemblies, non-threaded objective bells, or non-matching objective sizes including 24mm, 32mm, 40mm, 42mm, 44mm, and 56mm diameters; these setups require dedicated AO flip-up caps, slip-on covers, or alternative sized thread-in optic caps.
