-
Iterative Adjustment and Confirmation
Windage adjustment is an iterative process. It requires careful observation of shot placement at the chosen zeroing distance. After each adjustment, firing a group of shots confirms the effectiveness of the change. If the shots are still impacting left or right of the desired point of impact, further windage adjustments are needed. This process continues until a tight group is achieved, indicating that the laser’s windage is correctly aligned with the weapon’s bore axis.
Proper windage adjustment is an essential step in achieving accurate targeting with a PEQ-15. By understanding the mechanics of windage, the function of the adjustment turret, and the influence of environmental factors, users can effectively zero their devices and ensure optimal performance in various shooting scenarios. This precision enables consistent and reliable target engagement, maximizing the utility of the PEQ-15 as a valuable aiming tool.
4. Elevation Adjustment
Elevation adjustment plays a critical role in achieving a precise zero with a PEQ-15 laser aiming device. This adjustment compensates for the projectile’s ballistic trajectory, influenced primarily by gravity. Because projectiles follow a curved path downwards after leaving the barrel, the laser’s projected straight line must be adjusted vertically to intersect the trajectory at the desired range. This intersection represents the zero point, where the point of aim and the point of impact converge. Without proper elevation adjustment, the laser’s point of aim will not accurately reflect the projectile’s point of impact, leading to vertical deviations in shots.
Consider a scenario where a rifle is zeroed at 50 yards. If the elevation is set too low, the projectile will impact below the laser’s point of aim. Conversely, if the elevation is set too high, the impact will be above the point of aim. Precise elevation adjustment is therefore crucial for achieving accurate shot placement. This adjustment is performed using the elevation turret on the PEQ-15, which allows for incremental vertical shifts in the laser’s projected point of aim. These adjustments are made in conjunction with windage adjustments to achieve a perfect zero, where the laser accurately represents the projectile’s point of impact at the designated range. For example, a shooter may make incremental adjustments to the elevation turret, firing groups of shots after each adjustment and observing the impact points relative to the laser’s point of aim. This iterative process continues until the point of impact consistently aligns with the point of aim, confirming the correct elevation setting.
Accurate elevation adjustment, in conjunction with precise windage adjustment, is fundamental to realizing the full potential of a PEQ-15. Mastery of this process allows users to confidently engage targets at varying ranges, knowing that the laser’s point of aim accurately reflects the projectile’s point of impact.
