Setup and Mounting

Proper mounting is crucial for the accuracy and performance of your Burris Fullfield IV riflescope. Always ensure your firearm is unloaded and pointed in a safe direction before beginning any work on it.

Mounting the Scope

1. Choose Appropriate Rings: Select high-quality scope rings that match the 1-inch tube diameter of your Fullfield IV riflescope. Ensure the rings are compatible with your rifle's mounting system (e.g., Picatinny, Weaver).
2. Secure Base and Rings: Attach the scope base securely to your rifle's receiver according to the manufacturer's instructions. Then, attach the bottom halves of the scope rings to the base, ensuring they are properly aligned.
3. Position the Scope: Place the riflescope into the bottom halves of the rings. Adjust the scope's position forward or backward to achieve proper eye relief. This is the distance between your eye and the eyepiece when you are in a comfortable shooting position.
4. Level the Reticle: Rotate the scope within the rings until the reticle is perfectly level with the rifle's bore. A scope leveling tool is highly recommended for this step to ensure consistent aiming.
5. Tighten Rings: Install the top halves of the scope rings. Gradually tighten the ring screws in an alternating pattern (e.g., diagonally) to ensure even pressure. Refer to the ring manufacturer's torque specifications to avoid over-tightening, which can damage the scope tube.
6. Final Check: Once mounted, double-check all screws for tightness. Ensure the scope is firmly seated and does not move when subjected to light pressure.

Operating Instructions

Magnification Adjustment

The Fullfield IV 3-12x42mm scope features a 4x zoom system. To adjust the magnification, rotate the power ring located near the eyepiece. The numbers on the power ring indicate the current magnification setting (from 3x to 12x).

Focusing the Reticle (Diopter Adjustment)

To ensure a crisp reticle image, adjust the diopter. Point the scope at a plain, bright background (like the sky) and quickly glance through the scope. Rotate the eyepiece until the reticle appears sharp and clear. Avoid staring through the scope while adjusting, as your eye may compensate for blurriness.

Windage and Elevation Adjustments

The scope features finger-adjustable turret knobs for windage (horizontal) and elevation (vertical) adjustments. Each click of the turret adjusts the point of impact by 1/4 MOA (Minute of Angle). To make adjustments:

• Remove the protective caps from the windage and elevation turrets.
• Rotate the elevation turret (top) to adjust for vertical bullet drop.
• Rotate the windage turret (side) to compensate for horizontal wind drift.
• After zeroing, you can reset the turrets to "0" by lifting the turret cap, rotating it to align the "0" mark with the indicator, and then pressing it back down. This allows for quick return to zero after making temporary adjustments in the field.

Ballistic E3 Reticle

The Ballistic E3 Reticle is designed for quick and accurate aiming at various distances and in windy conditions. It features holdover points for bullet drop compensation and wind dots for wind drift compensation. Familiarize yourself with the reticle's specific subtensions and how they correspond to your chosen ammunition's ballistic trajectory.

Care and Maintenance

Proper care will ensure your Burris Fullfield IV riflescope provides years of reliable service.

• Cleaning Lenses: Use a soft lens brush or compressed air to remove dust and loose debris. For smudges or fingerprints, use a clean microfiber lens cloth and a small amount of lens cleaning solution. Wipe gently in a circular motion. Avoid using harsh chemicals or abrasive materials.
• Cleaning Exterior: Wipe the exterior of the scope with a soft, damp cloth to remove dirt or grime. For stubborn marks, a mild soap solution can be used, followed by wiping with a clean, damp cloth.
• Storage: Store your riflescope in a cool, dry place, preferably in its original packaging or a protective case, to prevent dust accumulation and accidental damage.
• Avoid Disassembly: Do not attempt to disassemble the riflescope. This will void the warranty and can cause irreparable damage to the optical system.

Troubleshooting

If you encounter issues with your Burris Fullfield IV riflescope, consider the following common solutions before seeking professional assistance:

• Blurry Image/Reticle:
  • Ensure the diopter adjustment (eyepiece focus) is correctly set for your eye.
  • Check for condensation on the lenses. Allow the scope to acclimate to ambient temperature.
  • Verify that the objective lens and eyepiece are clean and free of smudges or debris.
• Inaccurate Point of Impact:
  • Confirm that the scope is securely mounted and that all rings and base screws are tightened to the recommended torque specifications.
  • Ensure the reticle is level with the rifle's bore.
  • Check for barrel obstructions or damage to the rifle itself.
  • Verify that you are using consistent ammunition.
• Turrets Not Adjusting:
  • Ensure the turret caps are fully removed and the turrets are not stuck.
  • If the turrets feel loose or unresponsive, contact Burris customer support.
• Fogging Inside Scope:
  • The scope is nitrogen-filled and fogproof. Internal fogging is rare and usually indicates a seal compromise. If this occurs, contact Burris for warranty service.
