2. Mounting the Sight
The PRO Target Reflex Red Dot comes with a Weaver low mount and is also compatible with pistol slides using a Delta Point Pro footprint.
- Ensure the firearm is unloaded and safe before proceeding.
- Attach the included Weaver low mount to the sight using the provided mounting screws and tools.
- Place the assembled sight onto your firearm's compatible rail system (e.g., Weaver or Picatinny rail).
- Align the sight properly and tighten the mounting screws evenly to secure the sight firmly to the rail. Do not overtighten, as this can damage the rail or sight.
- For pistol slide mounting with a Delta Point Pro footprint, follow the specific instructions provided by your pistol manufacturer for optic installation.
Operating
1. Power On/Off and Brightness Adjustment
The sight features an 8-setting brightness adjustment dial.
- To turn on the red dot, rotate the brightness adjustment dial (located on the side of the sight) clockwise from the 'OFF' position.
- Continue rotating the dial to cycle through the 8 brightness settings. Select the setting that provides optimal visibility for your lighting conditions.
- To turn off the red dot, rotate the dial counter-clockwise back to the 'OFF' position.

2. Windage and Elevation Adjustments (Zeroing)
The sight features 1 MOA detented elevation and windage turrets with 100 MOA of travel.
- Elevation Adjustment: The elevation adjustment turret is located on the top of the sight. To adjust the point of impact vertically, use a small flat-head screwdriver or the provided tool to turn the turret. Turning clockwise typically moves the point of impact down, and counter-clockwise moves it up.
- Windage Adjustment: The windage adjustment turret is located on the side of the sight. To adjust the point of impact horizontally, use a small flat-head screwdriver or the provided tool to turn the turret. Turning clockwise typically moves the point of impact right, and counter-clockwise moves it left.
- Zeroing: Perform zeroing at a shooting range following safe practices. Fire a group of shots, observe the point of impact relative to your aim point, and make precise adjustments to the windage and elevation turrets until your shots consistently hit the desired target area. Each click of the turret corresponds to 1 MOA (Minute of Angle) of adjustment.

Maintenance
1. Cleaning
- Lenses: Use the provided lens cleaning cloth or a soft, lint-free cloth specifically designed for optical lenses. Gently wipe the lens surfaces to remove dust and smudges. For stubborn marks, a small amount of lens cleaning solution can be applied to the cloth, not directly to the lens. Avoid using abrasive materials or harsh chemicals.
- Body: Wipe the exterior of the sight with a soft, damp cloth to remove dirt or debris. Do not use solvents or strong cleaning agents.

- Store the sight in a cool, dry place, away from direct sunlight and extreme temperatures.
- If storing for an extended period, it is recommended to remove the battery to prevent potential leakage.
