Parallax Focus Adjustment - AO - Adjustable Objective (front lens casing)
Parallax effect is the term that describes the difference in angles between objects that are seen up close and those seen far away. When you look at telephone poles passing by on the side of the road, those closest to your car seem to pass very fast, while the ones far away seem to go very slow. That difference is due to the parallax effect.
The reticle in your scope is like a telephone pole that's very close. If you move your head on the stock while watching the target through the scope the reticle may seem to move, wobble or blur against the target. That affects where you perceive the aim point to be, and that affects your accuracy. Parallax focus correction adjustment reduces this phenomenon to the greatest extent possible.
Parallax focus correction therefore is a must for anyone attempting to use either a high magnification scope, shooting drastically different yardages with the same scope or anyone attempting to shoot at extremely close ranges or extremely long ranges. Especially so if it is a combination of these factors.
This scope features Parallax focus correction from 15 yards to infinity.
Adjusted by the objective i.e., it is an AO "Adjustable Objective" scope.
