The Hawke Professional Flip-Up Cover – Ocular (44mm) for Frontier Models (Hawke 61151) is a high-grade machined aluminium protective cap designed for threadless 44 mm riflescope eyepiece assemblies. Engineered specifically for Hawke Frontier optics, this passive mechanical accessory replaces standard rubber covers to deliver rugged lens protection against dust, grit, rain, and physical impact. Built with internal mechanical position stops, the cap folds back flat or holds securely at chosen angles, while its 360-degree clamp-on interface permits customizable left-, right-, or upward-flipping opening positions to suit individual shooting preferences and bolt clearances.

Key Features

• Machined Aluminium Construction: Manufactured from high-grade aluminium with a matte black finish to resist extreme field temperatures and heavy centre-fire recoil without softening or becoming brittle.
• Internal Position Detents: Mechanical position stops hold the cover securely open at fixed angles or flat against the riflescope body during firing strings.
• 360-Degree Rotational Mounting: The friction clamp-on mechanism allows installation in any orientation for left, right, or vertical flip activation.
• Direct 44 mm Eyepiece Fit: Designed for an exact friction fit over 44 mm outer ocular scope rims, ensuring a tight seal against environmental debris.

Who is the Hawke Ocular Frontier for?

• Hawke Frontier Riflescope Owners — Secures a dedicated 44 mm clamp-on diameter aluminium flip-up ocular cover specifically engineered to match threadless 44 mm Frontier eyepiece assemblies against physical lens scratches.
• Australian Bush Hunters and Pest Controllers — Requires a 44 mm clamp-on machined aluminium ocular cover that seals out red dust, grit, and rain in harsh environments while withstanding heavy centre-fire recoil.

Less suitable for: Riflescopes with 46 mm ocular bells (which require model 61152), standard Vantage or Endurance WA scopes, threaded objective lenses, or transit scenarios requiring full body and turret protection where a full neoprene scope cover is better suited.
