Basics of Rifle Scope Adjustment

Adjusting a rifle scope is an essential part of shooting. It allows the shooter to make precise shots by aligning the scope with the rifle. There are two main types of adjustments: windage and elevation. Windage adjusts the horizontal alignment of the scope, while elevation adjusts the vertical alignment.

The most common unit of measurement for scope adjustment is the Minute of Angle (MOA). MOA is a unit of angular measurement that is equal to 1/60th of a degree. One MOA at 100 yards is approximately 1.047 inches. This means that if a shooter adjusts their scope by one MOA at 100 yards, the point of impact will move by approximately 1 inch.

The reticle is the crosshairs or other aiming point in the scope. It is important to ensure that the reticle is centered in the scope before making any adjustments. This can be done by adjusting the eye relief and focus of the scope.

Zeroing the scope is the process of adjusting the scope to match the point of impact of the rifle. This is typically done at a specific distance, such as 100 yards. Once the scope is zeroed, the shooter can make adjustments to the scope to compensate for bullet drops at longer distances.

Alignment is critical when adjusting a rifle scope. The scope must be aligned with the rifle’s bore to ensure accurate shots. This can be done by using a bore sight or by adjusting the scope while shooting at a target.

Internal adjustment is the process of making adjustments to the scope’s internal components. This is typically done by adjusting the turrets on the scope. The turrets control the windage and elevation adjustments.

Understanding the basics of rifle scope adjustment is essential for accurate shooting. Windage and elevation adjustments, MOA measurements, reticle centering, zeroing, alignment, and internal adjustment are all important factors to consider when adjusting a rifle scope.
