The Best 3-9×40 Scope: Ultimate Selection and Guide (Top 5)

If you’re looking for the best 3-9×40 scope you’re in the right place because we’ve put together this top 5 list just for you. The 3-9×40 has become a staple for North America hunting because it gives you a lot of what you need without needless frills.

Below you’ll find a quick table with the 5 scopes we recommend. There’s both budget friendly options or options great for the money along with my personal favorites in this category from Leupold and Vortex. You’ll find a break down of each scope further down this article.

What To look For In Your Scope

Picking out a scope isn’t very difficult but there are a couple factors to consider when making your purchase. The features such as focal plane, reticle, and resolution to name a few are important traits to pay attention to. While all of the best 3-9×40 scopes on our list of five are excellent options there may be one more suitable to your needs.

Below I’ll quickly go over some traits or characteristics you may want to take into consideration while making your scope decision. Hopefully this way you’ll have taken everything into consideration before the purchase and make your best possible choice.

Your Shooting Environment

One of the most important things in my opinion is the environment you’ll be shooting in the majority of the time. If most your time will be spent in the woods you’ll need a scope that’s very durable, provides fog purging, water resistant, and overall has the ability to withstand these tougher conditions.

Range shooting or sport shooting is often done in better weather conditions. This lets you focus less on the durability of the exterior of the scope and maybe find a scope that puts your money into the glass, turrets, and clarity.

Unfortunately we don’t live in a perfect world and not all scopes excel in all areas. If you’re going for a 3-9×40 scope that budget friendly you’ll have to decide which traits are important to you. However, if you’re willing to spend the extra money on a higher end scope you can really get something special.

Does Focal Plane Matter?

The short answer is no focal plane doesn’t matter. It really comes down to what you’re used to or if you’re a beginner just find the one you understand easier. There’s always on ongoing debate on which focal plane is better for hunting and which is better for competition but it all boils down to personal preferences.

Detailed Features

The more detailed features or traits you want to look at are the reticle, zoom, parallax, and resolution. Each of the best 3-9×40 scope will vary so pay attention to the more detailed information of your scope.

Your reticle is very important. You can get a glass etched reticle or standard but the quality of glass with your reticle will make a big difference. Since it’s what you’ll be focusing on through your scope you need to make sure it’s a good one.

A lot of scopes lose clarity when you’re zoomed in at max. If you’re going to be using max magnification often make sure your scope has a reputation of clear images when at maximum zoom. If you’re going to be hunting with this scope most hunting is done around 300 yards so you should be fine without using the maximum.

The standard parallax for a 3-9×40 scope is around 50 yards with two options exist for magnification and resolution: digital or optical. Parallax is essentially an optical illusion that makes the reticle appear to move.

Resolution is another one of the most important things to consider for your scope. Most decently priced scopes will have a good resolution and that’s why I typically recommend staying away from very cheap scopes. As long as you’re spending at least a little money on a decent scope you should have something with good resolution. Make sure it’s high on your priority list.

Why Use A 3-9x40 Scope?

The 3-9×40 scope is popular because it gives you a lot of what you need without other extras. This means you’re getting exactly what you pay for without wasting money on other features you may not need. The 3-9×40 magnification of 3x is low but favorable for most hunting conditions.

This has made this type of scope ideal for hunting in North America. It still gives you enough magnification for a little longer distance shooting if needed. I think it will continue to grow in popularity because people want a practical hunting scope without worrying about the extra frills.

There are still choices to make though, You’ll choose between illuminated options, compact designs, but the majority of these scopes are classic, sleek, and won’t break your bank while providing you with a scope you can be confident in.

The Best 3-9x40 Scope

Below you’re going to find the 5 best scope options for your 3-9×40 scope purchase. Make sure to still take into consideration the features you want and what is going to be most important to you in a scope. Then find the one below that matches your criteria the best but any of these 5 scopes will make a great option!

Commonly Asked Questions

What does the 3-9×40 mean on a scope? – The 3 means three power or 3x. This means the image appearing through the scope is 3 times closer than it appears with the naked eye. The 9 means the exact same thing except at 9x closer than what the naked eye would see. Lastly, the 40 is the objective diameter of the lens in millimeters.

Is a 3-9×40 scope sufficient for long shots? – It will depend on some different factors such as your vision and type of game you’re hunting. However, you should be able to hunt deer size game at 100 – 300 yards very easily with this type of scope. When you’re at 9x with basic vision you should be able to hit at 450 yards.

Is it possible to mount a scope without a rail? – It is possible to mount a scope without a rail but it will require the help of a gunsmith if you want it done properly. It’s not something I would venture out and try without any experience.
