Magnification Power

The magnification power of a rifle scope is the zoom factor of how much the sight picture of your target is magnified. Magnification plays an important role especially when you plan to shoot your target from longer ranges. However, too much magnification will result in a smaller field of view of your target thus reducing the accuracy of your shot.

Hence, you should choose the right amount of magnification according to the ranges you plan to shoot from so you will get a wide field of view as well as a slightly enlarged image.

Reticle

A reticle basically consists of crosshairs in a circle which displays the position of your target. There are many type of reticles such as mil-dot reticle and BDC reticle in which the crosshairs and dots differs in arrangement for a specific purpose when hunting.

Also, some illuminated reticles in either red or green color comes in handy during low light conditions. Bright reticles are important so that you will have a high clarity and bright image of your target when hunting.

Objective Lens Diameter

An objective lens increases light transmissions which result in more light gathered in your scope so that the image of your target is bright and clear. Therefore, a larger diameter objective lens will increase the amount of light entering your scope hence improving the image quality of your target even under low light conditions.. However, it does not play a role in increasing the field view of your rifle scope.
