Things To Consider When Buying A .308 Scope


Once of the things you are going to want to consider when purchasing a scope is the magnification level and whether or not you want a scope with adjustable magnification. The amount of magnification you are going to want your scope to have will depend on a few different things such as:

  • The situation you will be using the gun and the scope in. Keep in mind that lower magnifications allows for more intuitive shooting. Scopes with 10X or less are best for shooting targets that are less than 500 yards away.
  • The more magnification adjustments a scope has the more the price will go up in most cases.

Objective Lens Size

Another thing you want to consider when buying a scope is the Objective lens size of the scope. The larger the Objective lens the brighter the object will appear. However, you do need to keep to mind that larger objective lenses adds weight to the scope. It may also mean that you will need to mount your scope higher over the barrel.

How the Scope is Adjusted

Another thing you will want to consider is how the scope is actually adjusted. There are basically two different types of adjustments the MOA and the Focal plane. Both have their advantages and disadvantages.
