Adjusting the Side Focus Parallax
Parallax is a perceived displacement of an object relative to a background when viewed from different angles. In optics, parallax can result in a misalignment between the point of aim and the point of impact when the scope is not properly focused. The side focus parallax adjustment on the Burris AR 332 scope allows you to correct this misalignment and ensure precise aiming at various distances.
To adjust the side focus parallax, follow these steps:
1. Set the Focus Range
Rotate the side focus adjustment ring until the yardage mark on the ring corresponds to the distance to your target. The yardage marks are typically labeled in 50-yard increments.
2. Adjust the Fine Focus
Once you have set the focus range, make fine adjustments to the focus by turning the fine focus ring. This ring is typically located behind the side focus adjustment ring.
3. Check for Parallax
Look through the scope at the target. If the reticle appears to move relative to the target when you move your head or eye, there is still parallax present. Adjust the fine focus ring until the reticle remains perfectly still on the target as you move your head.
4. Repeat for Other Distances
If you are shooting at targets at different distances, you may need to repeat steps 1-3 for each distance to ensure correct parallax adjustment.
5. Repeat to Check
After you have adjusted the parallax, check it again by looking through the scope and moving your head. The reticle should remain motionless on the target.
6. Fine-Tuning for Extreme Distances
For shots at extremely long distances (e.g., 1,000 yards or more), you may need to make very precise adjustments to the side focus parallax. To enhance precision, you can use a parallax adjustment chart. These charts provide yardage marks and corresponding side focus settings for specific models of rifles and scopes. Refer to the Burris website or consult with a knowledgeable advisor to obtain a parallax adjustment chart for your particular setup.
Maintaining Zero Stability
Ensuring the stability of your Burris AR 332 scope’s zero is essential for accurate shooting performance. Here are some factors to consider:
9. Scope Mounting and Tightening:
The mounting system plays a crucial role in maintaining zero stability. Ensure the scope is securely attached to the firearm. Use a high-quality mount, such as the Burris PEPR mount, and tighten the screws to the specified torque. Avoid overtightening that can damage the scope or mount. Check the screws periodically to ensure they remain securely tightened.
For optimal stability, consider using a torque wrench to apply precise and consistent force when tightening the screws. Aim for the recommended torque values provided by the manufacturer or the scope mount instructions. A torque wrench allows you to evenly distribute the force without overtightening or undertightening the screws, ensuring a solid and stable connection between the scope and the firearm.
Proper scope mounting and tightening help prevent the scope from shifting or becoming loose during shooting, which can affect zero stability. By following these guidelines, you can minimize the likelihood of zero drift and maintain consistent accuracy.
| Screw Type | Recommended Torque Value (in/lbs) |
|---|---|
| Base Screws | 15-25 |
| Ring Screws | 10-15 |
