What to Look Out for When Buying the Best Scope for 308 Sniper?

You don’t just buy the first scope you see. You have to check its features to determine if it is suitable for your .308 rifle. Here are some of them:

Magnification Power

The first thing you need to check when buying a riflescope for your .308 Sniper is the magnification power. Keep in mind that not because the other brand has higher magnification means it is better than others. You only need a very high magnification during deer hunting, elk, or game hunting. With regards to whether to choose fixed or variable zoom, it depends on individual preference. For hunting, select a scope that can acquire the target fast once you peek into it.

Eye Relief

In a .308 rifle, eye relief is less vital since it does not have much recoil compared to other ammunition with the same effective range. But it does not mean you will ignore it. For starters, you might have a hard time absorbing the recoil of the gun with your shoulder. It means it will not stop right away. You might hurt your eye and could lead to injury. Pick a scope with 3-1/2″ to 4″ eye relief.


The scope’s weight will depend on the lenses inside. If you prefer a light scope, pick the one with a fixed 9x zoom having a 42mm objective lens. But, it will not help you hit your targets beyond 900 yards. If you use it for hunting, you will definitely need a lighter scope.


The reticle or crosshairs will depend on how you shoot. For instance, if you prefer a long-range shooting, a BDC reticle is perfect for you. Reticles of this type have millings, so you can focus on the following adjustments bullet-drop, windage, and elevation with every shot. You can choose from different types of reticles depending on your shooting style and which reticle you are comfortable with.

Objective Lens

The objective lens is found in front of the scope, and its primary function is to allow light to enter the scope and provide a clearer view of the image. The bigger the objective lens, the more light penetrates the tube and the clearer the view will be. If you are shooting with poor light, this is of great help.

The bigger the objective lens, the heavier the scope will be. Look for a middle ground to view the image in high quality, without adding too much weight. For hunting, the 42mm objective lens is the best option. But if you want a bit higher, you can find the one with 50mm and with fixed zoom so it will not be that heavy.

Parallax Adjustment

For short to mid-range scopes, parallax is not as essential as the other features as these scopes are parallax-adjusted already. But. For long-range, parallax adjustment is something you have to focus on. Parallax takes place if the reticle and the target are not on the same focal plane. This makes the reticle move over the target once your eyes move in the scope. If you have a long-range scope, look for the one with parallax adjustment, the one with a turret at the top of the tube.


If you will be using your rifle for hunting, this feature is quite vital. You will never know when it will rain, so it is better to have a scope that remains functional in any weather. Sometimes you will be greeted with thick fog, rain, or both. Choose the one that can handle all types of weather, including shock, so don’t worry if you accidentally bang your scope on rocks and trees while hunting.

Lens Coating

Riflescope lens coating can absorb more ambient light in a low light environment as it reduces the glare making it hard to aim accurately. Lens coating reduces the reflected light that could affect the accuracy of your scope. You can choose from coated, fully coated, multicoated lenses, and fully multicoated optics.

What Makes a Great .308 Scope?

The .308 Sniper is one of the most popular hunting gear all over the world. It has a longer range of up to 1000 yards and is one of the top-performing ammunition today. To take advantage of its long effective range, you need to match it with a compatible scope that can provide you a better sight picture up to 800 yards. Keep in mind that achieving 1000 yards is difficult not unless you took a class in hunting or are an army-trained sniper.

The .308 Winchester has minimal recoil, which makes eye relief less of a priority. But, always keep a distance between your eye and the eyepiece, as the rifle might have a hard time kicking back. You can look for a scope with around 3-1/2 inches to 4 inches eye relief is sufficient.

The magnification power and other scope aspects will depend on the purpose of using the rifle. If your purpose of using it is for hunting, you should keep your scope as lightweight as possible. If you are into game hunting, you need to be as close to your target as possible. It would help if you did not attempt to shoot it from 800 yards away. The most will be shooting from 150 yards if you use a .308 Winchester. A scope that performs at 9x or 12x is good enough.

Frequently Asked Questions (FAQ)

What size scope should I get for the AR .308?

The size of the scopes for an AR .308 varies, and it is not right to say that one is better than the others. It is subjective. You can choose any size of scope. Just make sure it will fit your AR, perform well, and provide the quality you need.

You can buy the biggest one you can find in the market. Make sure it will not interfere with the rifle functions. If you select a scope that will not fit the use, you intend for it. Then it is worthless.

To determine how big the scope you need, focus on its objective lens. For example, a scope with a 50 mm objective lens is far bigger than a 42 mm objective. Even if the 50 mm objective scope can collect more light, it is too bulky if you use it for hunting. It is a must that you pick the right size of the scope based on what you need.

Nikon M-308 vs. P-308: Which one is better?

Nikon M-308 riflescope is superior than P-308 Nikon riflescope. Although these two have the same features, the M-308 has the edge because of the premium features you cannot find in the P-308. Some of these features include the higher magnification, large range of FOV and eye relief, and the parallax setting.

The Nikon P-308, on the other hand, is much cheaper than M-308. Also, the additional features of M-308 are vital features for long-range shooting. So, when it comes to value, the P-308 is better than the M-308.

Nikon Buckmasters II 3-9x 40mm vs. Leupold Mark AR MOD 1 Riflescope: Which one is better?

Leupold Mark AR and Nikon Buckmasters II have the same features but from different companies. Both Nikon Buckmasters II and Leupold Mark AR MOD are designed for short and medium-range shooting. For those who do not know, the profiles of these two riflescopes are almost identical. But, the Nikon Buckmasters II is much cheaper than Leupold.

The Leupold Mark AR MOD 1 was made in the USA, so if you do not have enough budget and want a riflescope with the same quality as Leupold, choose the Nikon Buckmasters.

Leupold VX-2 3-9x40mm Riflescope vs. Leupold VX-3i 3.5-10x40mm Riflescope: Which one is better?

These two scopes belong to the same company, but one is better than the other. The Leupold VX-3i has the advantage over the VX-2. The VX-2 is the type of hunting scope you bring during a regular weekend hunting adventure.

The VX-3i with a matte black exterior has more to offer. One important thing you should know. It is more expensive than the VX-2 model may be because it has more features.

If you think you only need a regular but reliable scope, buy the Leupold VX-2. It is the best option if you prefer something exceptional to push the .308 to the test.

What is the Effective Range of a 308?

The most effective range of a .308 is an 800-meter maximum, but the USMC says it’s a 1000 yard maximum effective range. Many shooters agree with 800-meter and indicate it is the maximum limit for reliable hits in harsh weather.

What scope should I put on my 308?

Search for a scope that can provide 3 ½ to 4 inches of eye relief so you will be on the safe side. Choose an optic with greater eye relief if you prefer a scout rifle set-up that enables you to use the scope with both eyes open.

What is the best scope for ar 10 308?

If you choose medium-range targets, meaning your targets are 400 to 700 yards, buy the 4x to 9x scope with a 30-40mm objective. For a long-range shot, this refers to target 700 yards and above. It would be best to have a scope with 9x magnification and a 40 mm plus objective lens.

How far can a 308 shoot?

Ideally, a 308 can shoot accurately up to approximately 1000 meters at sea level pressure. But with the advancement of aerodynamical ability in projectiles, the range has extended even further by choosing the appropriate bullet for longer distances.

Will a 308 kill a deer at 400 yards?

The .308 riflescope is powerful enough to kill deer, moose, bear, elk, and pronghorn out to 300 yards, but the bullet drops quickly, and the trajectory is similar to the bell-shaped curve 500 yards. For 400 yards, a long-range riflescope is enough.

What magnification do I need for 1000 yards?

When it comes to magnification, 18x to 25x is ideal for 1000 yards. It depends on the shooter’s preference. Some hunters prefer to go lower than 18x, sometimes even as low as 10x, as higher magnifications can result in further issues.

How Much Eye Relief Do I Need for .308?

For .308, the scope that maxes out at 9x or 12x is enough to provide for your needs since most hunters will be shooting from 150 yards.
