Things to consider when purchasing the best scopes for 308 rifles

There are numerous scopes for 308 rifles in the market. Choosing the right scope for your needs can be confusing. You should look at several things when making your purchase if you don’t want the scope to disappoint you in the future. Here are some of these factors.


Magnification power is arguably the first thing you should look at when purchasing a scope for a 308 rifle. How much magnification will you need? It all depends on your particular use. Some scopes have higher magnification when compared to others.

However, this does not mean that it is better all around. Many are the times ultra-high magnification will not be necessary. You don’t need high magnification if you will be hunting game and deer. Should you go for a fixed zoom or variable zoom? It is very subjective. It is important to consider a scope that target scopes easily the moment you peek into it.

In most cases, the amount of magnification will mainly depend on the following factors:

  • Your budget. Scopes manufactured with more magnification adjustments are more expensive.
  • The specific situation you will be using your scope. Intuitive shooting will be possible with lower magnification. You should purchase a scope with 10x if you will be shooting less than 500 yards.

Objective lens

Objective lens is another important thing you should never forget when purchasing a scope for your 308 rifle. Normally, an objective lens is found at the front of the scope. The function of the objective lens is to allow light to come into the scope. This will give you a clearer sight picture. You need to have a clearer image when shooting at low light conditions.

What does it mean with a larger objective lens? This guarantees you brighter images. However, you should note that scopes manufactured with a larger objective lens are heavier. Away from that, you will be required to mount your scope higher over the barrel.

Eye relief

Eye relief is not of much concern when it comes to the 308 Winchester. The main reason behind this is that it does not have as much recoil as other ammunitions with the same effective range. But this does not mean that you should ignore a 308 rifle scope with better eye relief. Is it your first time to use a rifle? In that case, you might have a hard time absorbing the recoil of the rifle. This means that you will have a long way to go before it stops. You will end up being hurt if your eye socket is in its way. This might cause a serious injury.


The weight of a 308 rifle scope can be due to a number of sources. In most cases, most of the weight in the rifle scope comes from the lenses inside. Therefore, you will be forced to make a compromise at this particular point. It is advisable to get something with an objective lens of 42mm. Unfortunately, you might not be able to use this type of scope for hitting targets 900 yards or more away. Do you want to be using your scope for hunting? In such instances, you should buy something that will not add more weight to your gear.


The reticle in your 308 rifle scope will depend mainly on how you like shooting. For instance, a BDC reticle might be the best for you if you like shooting long distance. Most of the reticles in the market are manufactured with millings. Therefore, you should consider the bullet drop and elevation adjustments with every shot.

You can choose from a wide range of reticles available in the market. There is no reticle that is better when compared to the other. It will depend on your style of shooting and the specific reticle you are comfortable using.

Parallax adjustment

Parallax is not a significant issue in mid-range scopes. The reason behind this is that such scopes are already parallax adjusted to those ranges. Parallax should be a major consideration in long range scope. You will be required to deal with it constantly.

When does parallax happen? It occurs when the reticle is not in the same focal plane as the target. In such conditions, the reticle will move over your target when your eyes move in relation to the scope. Do you want to have a long range scope? You should look for one with parallax adjustment. They are manufactured with a turret at the top of the table.


It is an important factor especially if you will be using your rifle for hunting. It is quite hard when someone goes out hunting to find a perfectly clear day with nary dark cloud in sight. In most cases, you will be forced to hunt in the rain and thick fog. At times, it will be a combination of both. You can agree with me that this must be hectic.

This is the right time to go for a scope that can handle any kind of Mother Nature. Ideally, you should look for a waterproof and dustproof 308 rifle scope. When you have it, you don’t have to worry about banging your scope on trees and rocks.

Lens coating

The role of the lens coating in a rifle scope is to help it absorb as much ambient light as possible. Glare will be reduced. Kindly keep in mind that it can make it hard for you to aim properly. Additionally, the amount of light reflected by the lenses will be minimized drastically. It is very important since the reflected light does not only add to the glare. Besides that, you will know the location to your target.

Lens clarity

Do you know that a low quality scope will behave badly? Sunny weather may also cause unwanted reflections. What matters here is not having a clear view through the scope. With that in mind, you should look for those ones that won’t fail you when you are out in the open. Light transmission is another thing you should consider. Light transmission affects your final image the most.

Nowadays, most lenses manufacturers treat their products. This not only reduces glare but also maximize light transmission through them.

Mounting options

Mounting is the first crucial part of adjusting your scope appropriately. While some of the scopes come with mounting rings, some don’t. You need to know the exact length of your scope tube. This will enable you to know the specific cantilevers that will work for it. Furthermore, you should take the ring into consideration. Most of the rifles in the market are designed with base. What if the specific rifle does not have a base? You need to get one. Remember to invest in a quality base. It should fit perfectly into your rifle. The manufacturer lists the best bases that work perfectly with your rifle. There is nothing annoying like trying to fix all that out in the field.


There are few things to mention such as zooming in and out when it comes to adjusting your rifle scope. Changing the elevation is done via the magnification ring. The ring is located near the objective lens and via the turrets located in the middle of the scope.
