Magnification: This refers to the level of detail that a scope can provide at a given distance. A scope with a higher magnification will allow you to see your target more clearly, but it may also make it more difficult to acquire a target quickly.

Objective lens size: The objective lens is the lens at the front of the scope, and it determines how much light the scope can gather. A larger objective lens will allow for a brighter, clearer image, but it may also make the scope heavier and more difficult to mount on your rifle.

Reticle: The reticle, also known as the crosshairs, is the aiming point in the scope. There are many different types of reticles available, including duplex, mil-dot, and ranging reticles, each of which has its own specific features and benefits.

Eye relief: Eye relief is the distance between the eyepiece of the scope and your eye, and it is important to consider when shooting a rifle with a lot of recoil. A scope with a longer eye relief will allow you to shoot more comfortably, as it will help to reduce the amount of force that is transmitted to your eye.

Durability: It is important to consider the durability of a scope, as it will be subjected to a lot of wear and tear while being used in the field. Look for a scope that is made from high-quality materials and that has a durable finish to ensure that it will last for many years.

Price: Finally, consider the price of the scope, as it can vary widely depending on the features and quality of the product. Determine your budget and look for a scope that offers the features you need at a price that you can afford.
