How to Buy the Best 3-9x40 Scopes​

How to Buy the Best 3-9x40 Scopes​

There is a good 3-9x40 scope for you out there whether you are a pro target shooter or a regular hunter, and all you need to do is to find it.

To ensure that you choose the right scope from the many options available, it is important to watch out for the following things when shopping.

1. Reticle

The reticle is a crucial part of a 3-9x40 scope and any other type that you might have as it is what makes it possible to pick up a target and aim, and so it is one of the most important things to consider when shopping.

While different manufacturers will offer their scopes with different reticles, there are typically three main types which are duplex, mil-dot and the BDC reticle.

If you are a beginner and prefer to keep things simple and easy to use, the duplex reticle is always the best choice. But, if you also want something that that can help with things like range estimation and bullet drop compensation mil-dot and BDC reticles respectively will be more ideal.

2. Lens Size

The lens size (more specifically the objective lens) determines the amount of light that the scope is able to gather and hence the brightness and clarity of the sight picture.

A 3-9x40 scope will have a 40mm objective lens diameter which is a great size. And this is not only because it is large enough to let more light in but also because it will not make the scope too heavy.

But, you can still get 3-9x scopes with larger lens sizes such as 50mm or even smaller 32mm ones. When it comes to the lens size, you will need to strike a balance between the amount of light you want to gather and the weight it will add to your rifle.

3. Material and Design

Materials used to make the scope will determine its durability and ruggedness or ability to withstand the harsh outdoor environment.

Aircraft-grade aluminum alloy is by far the best rifle scope material as it is not only tough but also lightweight enough to ensure the scope does not make your rifle too heavy.

Also, a scope that is nitrogen on argon-filed and O-ring sealed will also be generally more durable and will provide a fog, water, and shockproof performance.

For the design, a scope that will come with a matte black finish or any other dark finish is better than a gloss finish because it is less reflective and hence less likely to attract your prey’s attention.

4. Ease of Use

The ease of use of a 3-9x40 scope just like with all other scopes is quite subjective. What an experienced hunter might find straightforward to use might be complicated for a beginner.

However, when choosing your scope there are certain things that you should watch out for to ensure that the scope will be easy to use.

Key among them is the ease of mounting it on your rifle, and those that come with the mount rings will give you an easier time. Also, an easy to use scope is one that is easy to sight in and will hold zero well to ensure you do not have to keep adjusting.

Also, a scope with some easily adjustable zero locking and resettable turrets will give you a much easy time as it will be easier to adjust the windage and elevation settings.

5. Price

If you want to get top quality and high-performing 3-9x40 scope, you should not focus a lot on the price but should instead pay more attention to its build quality and features.

However, you cannot overlook the price when buying anything as you can only get what you can afford. Also, cheap scopes do not always have to be terrible quality as some brands are known to produce some high-quality but fairly priced scope.

Hence, you should come up with a budget by deciding on whether you want a basic under $50 scope or a more advanced model. Once you have the budget in mind, you should then shop for the best scope within that price range.


With the many top-notch quality 3-9x40 scopes in the market, you should not have a hard time picking one for mounting on your gun.

But, to choose the best 3-9x40 scope, you need to consider important things like the reticle type, lens, material and other factors not mentioned on our buying guide such as the field of view and turrets.

And in this piece, we have done most of the hard work for you by reviewing 10 fantastic 3-9x40 scopes, and all you now need to do is pick one that suits your needs.
