Choosing the best scope for a 308 rifle is easier than you think. The 308 is a rifle which is designed to shoot a bullet at a long distanced target. The 308 is about the best tactical rifle, but it’s not necessarily for only snipers. It’s a great rifle for hunting too, especially large and medium game.

Nikon M-308 4-16x42mm



Leupold 115390 Mark AR Mod 1 3-9×40 mm



Bushnell Elite 6500 2.5-16x42mm Mil Dot Reticle


Requirements for the best 308 Riflescope

1. Clarity and distance capability

Since 308 rifles are designed for long range shooting, scopes for such rifles should be precise up to 300 yards and above. If the riflescope is accurate only to 250 yards, but at increased magnification lacks clarity, the rifle will not be perfect for long distance shots, irrespective of the circumstance.

This does not mean there are not some wonderful short to medium range scopes which will work perfectly on a 308 rifle. There are. This simply means, overall, for 308 rifles, the scope isn’t the best.

When we talk about clarity, we mean a scope which does not show a view that is distorted at extended magnification and shows a very clear image view under both low light and bright light conditions.

2. Durability

The best 308 rifle scope should be one that satisfies its purpose. It might not be used in tight areas where limbs and branches might be an issue. But then, the lenses have a need for treatment to make them resistant to scratch.

The tube has to be sealed, usually filled with argon or nitrogen to resist fog, and should have a solid construction. The riflescope’s interior parts are protected by the sealing and filling with gas which makes it more durable. What the riflescope is made of should be given consideration, because you need something that is not going to get damaged easily. It’s also important for the scope to be shock resistant because hard recoil can occur on a 308 rifle. Most 308 rifles are usually bolt action; hence, the best scope for a 308 rifle must be able to resist the shock that occurs from the locking into place of the bolt.

Buying a quality rifle scope means it should take a long period before it is replaced for the same purpose, assuming that the scope is well maintained. Thus, the scope needs to be well built and durable. Naturally, it is not easy to know how durable a scope will be. There are yet some indicators which would prove how long the scope is likely to last for.

3. Easy to use

Great scopes shouldn’t be hard to use, should be easy to decrease or increase magnification and should not take too much time in sighting them in. After sighting in, a good scope should remain steady, so it’s not necessary for it to be sighted again after the rifle has fired a few rounds. This is important not only for a 308 but all riflescopes. However, this is essential for long range scopes. If a scope doesn’t remain sighted in at 400 yards, a shooter can miss his target if it’s not aligned even slightly.

The dials have to be simple to adjust and to read. The scope’s eye relief has to be comfortable, and the reticle has to be clear. If the scope’s eye relief is not right or its reticle is not clear, it isn’t simple to use.

The objective lens’ diameter is important too. A longer diameter will show a better view, which will make it easier finding and tracking a target. The scope is not simple to use if finding your target is difficult.

4. Cost

A high grade 308 scope and a cheaper one could have a big difference in their cost. Normally, the high-quality scopes cost much. But this shouldn’t be true for all situations. What the rifle and scope will be used for is a major factor.

For instance, with less than $50, you can get compact tactical riflescopes which are of high quality. However, these scopes are usually light weight, with an objective lens of about 32mm, and mostly do not have variable magnification. They are mainly less than 8 inches long too. Though these scopes are good, they wouldn’t fit for long range shooting like targeting a moving elk or deer. However, they might be okay for hunters who are likely shooting at a game less than 100 yards.

On the other hand, there are 308 rifles copes which cost more than $1000. As expected, the expensive scopes usually have high-quality components and more features. So before buying a scope, it is advisable to consider the purpose of the scope carefully. We know that ‘cheap’ implies an inferior product, but this doesn’t apply always. Also, that a rifle scope is very costly does not mean it’s the best .308 riflescope. As important as the price is, it certainly is not the most important factor that requires consideration. The best .308 Riflescope will probably be within the range of $350 and $1000.

With all these requirements in mind, we will now look at the best scopes for a 308 rifle.
