  2. Carefully align the sight's base with the rib rail on your shotgun.

Operating Instructions

Reticle Illumination

This red dot sight features a fiber optic illumination system, which means it does not require batteries. The reticle's brightness automatically adjusts based on the ambient light conditions. In sufficient sunlight or artificial light, the red dot will appear clearly on the lens.

Windage and Elevation Adjustment

The red dot sight allows for windage (horizontal) and elevation (vertical) adjustments to zero your sight. Use the provided Allen wrench for these adjustments.

  • Elevation Adjustment: The front centerscrew is used to adjust the height. Tightening this screw will lower the point of impact (POI). The rear centerscrew is used to adjust the height. Tightening this screw will raise the point of impact (POI).
  • Windage Adjustment: The left front screw and right front screw are used to adjust the sight horizontally. Adjust these screws to move the point of impact left or right as needed.

Perform adjustments incrementally and test fire to achieve desired accuracy. Always ensure the screws are snug after adjustment to maintain zero.

  • Cleaning Body: Wipe the aluminum body with a soft, damp cloth to remove dirt and debris. Avoid harsh chemicals or abrasive materials.
  • Storage: Store the red dot sight in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, ensure it is clean and dry.
