Best Scopes For The Ruger AR-556

Sport hunting is a serious business. Gun owners and rifle enthusiasts are always on the lookout for the best rifle on the market. And a lot of thought is also given to the accessories that might be available for rifles as well.

The Ruger AR 556 is a semi-automatic rifle. It is made from forged aerospace-grade aluminum. Fans of the Ruger AR  556 enjoy using it at the shooting range and for sport. Part of the fun of using your rifle for sport, is the ability to add on accessories. Using accessories with your rifle will allow you to achieve better shots and scores.

One of the accessories that can be added on to your Ruger AR 556 is a scope. A scope will magnify your vision when you are looking through it. The scope will help you hit targets that are at a greater distance. This heightened ability to see and aim at targets is a definite positive when sport shooting.

Simply put, scopes are based on a system of optics and magnification. Scopes will have an adjustment mid body for windage and elevation. The windage adjustment moves the reticle left and right. The elevation adjustment will move the reticle up and down. The goal is to have the settings just right so that the bullet will impact right at the junction of the crosshair.

Most scopes should also have a focus adjustment. This can be a knob that turns or an adjustable eyepiece. This adjustment really helps to sharpen the focus on the object you are viewing.

Additionally, some scopes will have a variable magnification option. This is usually a ring that will adjust the magnification near the forward end of the eyepiece.

And finally, some scopes might have an illumination adjustment. This option helps adjust the light level in the scope. The advantage to having this option is the increased ability to shoot in different light levels.

Since scopes can be mounted at different places along the rifle; it will depend on the magnification level and the length of the eye box.
