Setup
Mounting the Riflescope
- Choose Appropriate Rings: Select high-quality rings that match your rifle's mounting system and the riflescope's 30mm tube diameter.
- Secure Mount: Attach the rings to your rifle's base according to the manufacturer's instructions, ensuring they are properly aligned and torqued.
- Position Riflescope: Place the riflescope into the rings. Adjust its position forward or backward to achieve optimal eye relief.
- Level Reticle: Use a reticle leveling tool to ensure the reticle is perfectly level with the rifle.
- Tighten Rings: Securely tighten the ring screws evenly, following the manufacturer's recommended torque specifications to prevent damage to the scope tube.
Zeroing the Riflescope
- Bore-Sighting: Begin by bore-sighting your rifle to get the initial point of impact close to the target.
- Initial Shots: Fire a few shots at a target at your desired zeroing distance (e.g., 100 yards).
- Adjust Turrets: Use the elevation and windage turrets to adjust the point of impact. Each click of the turret corresponds to a specific change in MOA (Minute of Angle) as indicated on the turrets.
- Set RZR Zero Stop: Once zeroed, follow the instructions in the detailed manual (not provided here) to set the RZR Zero Stop, allowing for quick and precise return to your established zero.

Operating the Riflescope
Magnification Adjustment
Rotate the magnification adjustment ring located near the eyepiece to change the magnification level. The 2-10x32 model offers a versatile range for various shooting distances.

Parallax Adjustment
The parallax adjustment knob is integrated with the illumination dial on the side of the scope. Rotate this knob to eliminate parallax error, ensuring the reticle and target are on the same focal plane at various distances. This is crucial for precision shooting.
Reticle Illumination
The illumination dial is part of the side focus knob. Rotate the dial to select one of the 10 brightness settings for the reticle. 'Off' positions are located between each setting to quickly turn off illumination without cycling through all levels.
