Most tactical-inspired and long-range centerfire scopes have a side knob for parallax adjustment, sometimes called side focus. This will eliminate the parallax at that distance and make for more accurate shooting. When adjusting for parallax, simply turn the knob until both the reticle and the target are in focus simultaneously (or as close to in focus as possible). There’s an explanation for parallax, why it’s a problem, and how to tell if it’s a problem. Scopes with the adjustments on the front are called AO or A/O models. Weve got all of your outdoor needs covered with guaranteed low prices on all sporting and. As a result, if your scope is properly sighted in, your shot should go exactly where you want it to go.

Ive talked about scope parallax many times over the years because its such an important and misunderstood aspect of rifle performance. Since the reticle appears to move when you shift your gaze, you cannot be assured of a shot that will go where you think it should go. The problem with parallax comes in when you don’t have a direct line of sight to your target. It makes the target look out of focus when you move your head or eye slightly right or left from the. In this illustration, you can see that the focal plane for the target image and the reticle are the same, so you don’t have to adjust the parallax. The rifle scope parallax is a kind of optical illusion. When the angle at which you are viewing the image through the scope changes, so will the reticle position relative to the target image. You can see that it is in front of the reticle, which means you have a parallax problem. In the illustration above, the point where the focal lines cross and form an X is the focal plane for the target image. Instead, it moves the planes at which these two objects are in focus so that they are the same (so they’re coincident.) You can tell that you have a parallax problem if you shift your gaze slightly and the reticle appears to change position. It is very important that you understand that correcting for parallax does not change the focus of the reticle or the focus of the image. If they’re not focused to the same plane, you have a parallax problem, an optical illusion that has to be corrected or you won’t be able to shoot accurately. Two things get focused in your scope: the reticle and the image itself. Parallax is a situation where the focal plane in your scope is offset from the reticle. Let’s explore more on what this term means and how to figure out if it’s a problem for you. Parallax occurs when the target and reticle are on different planes within the scope. For scopes with adjustable parallax which is going to be the majority of them with magnification over, oh, 8X or so the first thing to know is to ignore the yardage markings on the parallax adjustment dial. It’s a common term used when describing scopes, but how well do you understand what parallax is? Even more important, is it something you should worry about? The answer to the second question is a definitive yes, if you’re a long-range hunter or shooter.
