Understanding MOA
What is MOA?
MOA, or Minute of Angle, is a unit of measurement commonly used in the shooting and optics industry to describe the adjustment and accuracy capabilities of rifle scopes. One MOA is equal to 1/60th of a degree, which translates to approximately 1.047 inches at 100 yards. MOA allows shooters to make precise adjustments to their scope in order to compensate for various factors such as windage and elevation.
Why is MOA important in a rifle scope?
Having a rifle scope with MOA adjustment capabilities is crucial for shooters who strive for accuracy and precision in their shots. By making precise MOA adjustments, shooters can compensate for wind drift, bullet drop, and other external factors that affect bullet trajectory. This ensures that the bullets hit the intended target by adjusting the scope’s crosshairs, compensating for any deviations caused by external factors.
How does MOA impact accuracy and precision?
MOA directly impacts the accuracy and precision of a shooter’s shots. By allowing shooters to make small adjustments to their scope, MOA helps to fine-tune the point of aim and point of impact relationship. Without MOA adjustments, shooters would have to guess the necessary holdover or hold-off, leading to inconsistent shot groupings and reduced accuracy. With MOA, shooters can achieve more consistent and accurate shots by making precise adjustments based on external factors.
Parts of the Rifle Scope for MOA adjustment
Identifying the windage knob
The windage knob on a rifle scope is typically located on the right side of the scope and allows for adjustments to account for wind conditions. It is labeled with directional indicators, usually “L” for left and “R” for right, indicating the direction in which the point of impact will move when the knob is adjusted.
Recognizing the elevation knob
The elevation knob, located on the top of the rifle scope, is used for adjusting the vertical point of impact of the bullet. It is marked with indicators such as “+” and “-” to indicate the direction in which the bullet impact will move when the knob is adjusted.
Use of the side parallax knob
The side parallax knob, found on some rifle scopes, is used to correct for parallax error, which occurs when the reticle appears to move in relation to the target when the shooter’s eye position changes. Adjusting the side parallax knob eliminates this error and ensures that the reticle remains focused on the target.
