2. Setup and Installation
The Glo-Dlo Pro sight is designed for universal fit on shotguns with vent rib barrels. Installation typically involves cleaning the mounting surface and securely attaching the sight using its adhesive backing.
Installation Steps:
- Prepare the Surface: Ensure the vent rib surface where the sight will be mounted is clean, dry, and free of oil or grease. Use an alcohol wipe if necessary and allow it to dry completely.
- Position the Sight: Carefully align the Glo-Dlo Pro sight on the vent rib, ensuring it is centered and straight.
- Remove Adhesive Backing: Peel off the protective backing from the adhesive strip on the bottom of the sight.
- Attach the Sight: Press the sight firmly onto the vent rib. Apply consistent pressure for several seconds to ensure a strong bond.
- Allow to Cure: For optimal adhesion, allow the adhesive to cure for at least 24 hours before extensive use. Avoid exposing the sight to moisture or extreme temperatures during this period.


3. Operating Instructions
The TRUGLO Glo-Dlo Pro Fiber Optic Shotgun Sight utilizes ambient light to illuminate its fiber optic element, providing a bright, clear aiming point. This design is particularly effective in varying light conditions.
Usage Guidelines:
- Eye Dominance: The sight is designed to help eliminate problems with eye dominance, encouraging shooters to keep both eyes open for a wider field of view and improved situational awareness.
- Target Acquisition: The bright red fiber optic dot draws the eye quickly to the front sight, facilitating rapid target acquisition.
- Proper Gun Mounting: The low-profile design supports proper gun mounting and shouldering, contributing to consistent shooting form.
- Light Conditions: The fiber optic gathers available light, making the sight visible in bright daylight and low-light conditions. Performance may vary in extremely dark environments where no ambient light is present.
4. Care and Maintenance
Proper care and maintenance will ensure the longevity and optimal performance of your TRUGLO Glo-Dlo Pro Fiber Optic Shotgun Sight.
Maintenance Tips:
- Cleaning: Periodically clean the fiber optic element and the sight housing with a soft, lint-free cloth. If necessary, use a small amount of mild soap and water, then dry thoroughly. Avoid harsh chemicals or abrasive materials.
- Inspection: Regularly inspect the sight for any signs of damage, such as cracks in the fiber optic or loosening of the adhesive bond.
- Storage: Store your shotgun in a clean, dry environment to prevent dirt and moisture accumulation on the sight.
5. Troubleshooting Common Issues
This section addresses common issues you might encounter with your fiber optic shotgun sight.
Troubleshooting Guide:
- Sight Appears Dim:
- Ensure the fiber optic element is clean and free of obstructions.
- Verify there is sufficient ambient light for the fiber optic to gather. Fiber optic sights rely on external light sources.
- Sight is Loose:
- If the sight becomes loose, the adhesive may have failed. Carefully remove the old adhesive residue from both the sight and the vent rib. Re-attach using a strong, weather-resistant adhesive suitable for firearms accessories.
- Ensure the surface was properly cleaned and dried before initial installation.
- Inaccurate Aiming:
- Confirm the sight is properly aligned and centered on the vent rib.
- Practice proper shooting fundamentals, including consistent gun mounting and sight picture.
