308 Scope Buyers Guide

Here are some tips that will help you find the right .308 scope for your rifle.

How to Pick the Best Product

The most important thing for you to remember when looking for a .308 scope is to ensure that it's compatible with your rifle. You can mount them on lots of different guns.

The second thing is to factor in the area where you intend to use it the most. Will your shooting occur in an open range or a deeply wooded area?

 What time of day will it be? Additionally, try to find one that has some level of protection for the lens. Eye relief is also detrimental to how well you'll be able to adapt to the scope.

Choose a scope that has a reticle that you're not going to be annoyed with seeing, and that will be easily viewed by you. And finally, consider the range in which the product is advertised.

 Of course, this may also depend on the rifle in use, but you may be able to stretch the maximum range of your weapon when mounting a scope that magnifies farther than 4x.

Scopes are usually made from dense materials that are difficult to break. Some of them will scratch much easier than others. There's no to know which won't scratch until you try it out for yourself, but you can minimize the chances of getting one that would.

Pay attention to what others have said about scope in question. Scopes that weigh a bit more might be less susceptible to receiving damage. Look at the placement of the turrets as well.

 Depending on how you shoot and your level of experience, they may get in your way if too large.

Using a .308 Scope for Hunting

If you're a hunter and plan on using a .308 scope for such events, you'll want to stick to those that offer good visibility in images. Also looking for a product that has varied levels of illumination.

What Is the Best Long Range Scope for 308?

In our opinion the best scope for 308 long range and medium range are: 

1. Vortex Optics Viper HS Second Focal Plane Riflescopes - Best Scope for Long Range (People's Choice)

Vortex Optics Viper HS Second Focal Plane Riflescopes

The Vortex Optics Viper HS is a riflescope that's recommended for people that require a solid reticle, or crosshairs.

There's nothing difficult about it at all. When you ready for a target, you will always spot it regardless of your level of magnification. However, some crosshairs have a tendency of getting in the way.

This one isn't too large either, offering more visual that models that block out too much from your field of view. Lenses are strong and entirely waterproof.

Although some adjustments would be better if they were loose, there's nothing frustrating about operating this scope on a .308.


  • Images that are seen through the optical are clear, even in the far corners of the scope
  • The lens if shielded with a coat that makes it scratch resistant
  • Reticle is easy to see but not too inconspicuous


  • The magnification adjustment is a bit tight, which may increase time spent before readying for a shot

2. Primary Arms FFP Rifle Scope - Best Scope for Optical Brightness


The Primary Arms FFP Rifle Scope has all the bells and whistles that one needs to make accurate shots. There's a battery inside (CR2032) tasked with controlling your brightness levels, something that could be extremely useful when shooting during twilight hours.

Shocks also won't faze the scope, whereby firing at a rapid pace will never cause harm to the lense or outer portions of the scope. And spotting won't be necessary until you reach approximately 150 yards. It is a bit on the heavy side, so you'll definitely notice it if moving away from a scope that's lighter than the FFP.


  • Contains a CR2032 battery that increases brightness in low-light environments
  • Isn't susceptible to shock damages
  • Spotting isn't a requirement for up to 150-200 yards


  • Quite heavy; adds a bit of weight to a rifle

  • Buttons and dials are easy to locate regardless of the amount of light available
