Begin by ensuring your rifle is unloaded. Use appropriate scope rings and a mounting base compatible with both your rifle and the scope. Position the scope on the rings, adjust for eye relief, and ensure crosshairs are level before tightening the ring screws evenly.
To zero your scope, start at a short range (25 yards) and fire a group of shots. Adjust the windage and elevation knobs to move the point of impact to the center. Repeat this process at your preferred zeroing distance (usually 100 yards).
Use a soft, lint-free cloth or a lens cleaning brush to remove dust. Apply a small amount of lens cleaner to the cloth (not directly on the lens) and gently wipe in a circular motion. Avoid using rough materials or excessive pressure.
Loosen the mounting rings slightly and rotate the scope until the crosshairs are level with the rifle. Use a bubble level for accuracy, and re-tighten the screws evenly once aligned.
Fogging is usually due to moisture. Ensure all seals are intact and consider using anti-fog sprays. Store the scope in a dry environment, and if the issue persists, contact Bushnell for possible repairs.
Use the ballistic drop compensation (BDC) reticle by aligning the target with the appropriate drop point mark that corresponds to the range. Refer to the user manual for specific calibration details based on your ammunition.
Regularly check and tighten all screws, keep the lenses clean, and store the scope in a dry, cool place. Avoid exposure to extreme temperatures and moisture, and periodically inspect for damage or wear.
Ensure the lenses are clean and free from obstructions. Adjust the eyepiece focus and make sure the objective lens is properly adjusted for the lighting conditions. Consider using anti-reflective lens coatings if available.
Ensure the scope is securely mounted and check for any movement in the mounting system. Verify that the ammunition is consistent and that environmental factors like wind are accounted for.
Check for debris or obstructions around the knobs. Ensure they are not over-tightened and inspect for any damage. If the issue persists, consider professional servicing or contacting Bushnell support.
