The Hawke Flip-Up Cover – Ocular Size 4 (Model 61053) is a precision-machined riflescope ocular lens protector designed to shield the eyepiece from physical impacts, field debris, dust, and inclement weather. Constructed from high-grade CNC-machined aluminium with a non-reflective matte black finish, this mechanical optical accessory provides heavy-duty physical protection over standard rubber or plastic alternatives. It is engineered specifically for riflescope models from 2015 onwards that feature Hawke's Size 4 ocular eyepiece bells, delivering a durable barrier for optics during storage, transport, and active field deployment.

Key Features

• High-Grade Aluminium Build: CNC-machined aluminium housing provides rigid impact resistance against direct brush strikes, scratches, and field abrasion.
• Single-Handed Deployment: Integrated spring-tensioned flip mechanism allows fast, one-handed opening and closing without losing line of sight on the target.
• Multi-Directional Opening: Configurable hinge system allows the cover to open and lock into user-selected orientations, including folding flat back, straight up, or sideways.
• Passive Mechanical Design: Completely mechanical design with zero electrical components, requiring no batteries or external power.

Who is the Hawke Flip-Up Cover – Ocular Size 4 for?

• Long-Range Precision Shooters — Requires an ocular riflescope cover engineered to fit the Size 4 ocular eyepiece bells of 34 mm main tube optics like the 3-15x44 and 5-25x56 Vantage HD 34 FFP configurations, keeping high-magnification ocular glass protected from dust between strings of fire.
• All-Weather Field Hunters — Requires a CNC-machined aluminium metal ocular riflescope cover designed to fit Size 4 eyepiece housings, offering one-handed opening and multi-directional positioning to protect 44 mm and 56 mm objective hunting scope ocular lenses in rain, mud, and abrasive terrain.

Less suitable for: Shooters requiring eyepiece protection for Frontier 30 SF riflescopes, Frontier 30 riflescopes, or XB/XB1 crossbow scopes, which require dedicated thread-matched professional scope covers, or shooters needing front lens protection, who require millimetre-matched objective flip covers.
