By keeping in mind, the following factors, you will easily buy the perfect rifle scope for under $400 you.


You are using a scope to increase your visibility like the thermal ones; hence, magnification is a very important aspect. In terms of magnification, most of the shooters think larger magnification is better. Everything depends on your shooting environment. Sometimes you will zoom in and sometimes you have to zoom out. So, the transition should be seamless for successful target acquisition.

But budget scopes may not always please you with their magnification transition. So, you need to pay extra attention to the magnification transition, when you are planning to buy a rifle scope under $400.

Objective Lens

The objective lens defines the area through which light enters the device. The larger objective lens allows a greater amount of light, as a result, a brighter image is generated. So, you should get a rifle scope with a larger objective lens if you are planning to use the scope in low light. But in that case, you will have to cost more. Therefore, you have to buy the one that comes with the best possible features in your budget.

When you are out there hunting squirrels or shooting targets, each ounce of weight matters, and a larger objective lens gets heavy with their size. So, you need to fine-tune your feature lists with your capability.

Lens Coating

Quality optics come with lenses covered with a specific type of coating so that your eyes and the lenses are protected. At the same time, quality coating assures better performance. Lens coating is of different types. Complete multicoating is the best in quality and they cost more than other types like full coating, normal coating, etc. Quality coatings have anti-glaring characteristics that result in the same crisp visibility almost all the time.

Therefore, you should go for the complete multicoating if possible. While buying the rifle scope under $400 check the lens coating carefully so that you don’t end up wasting your valuable money.


You are going to mount the scope on your rifle. So, you must be sure whether your chosen scope is the best fit for your scope or not.

When you are out there hunting or shooting, your rifle and the chosen scope must work seamlessly so that you can have a great shooting experience.

Some scopes have built-in mounts while you have to buy additionally for some other ones. Go for the one that fits the most with your rifle.

Construction Material

With each shooting, there will be moderate to heavy recoil that your scope must have to endure. Thus, scopes must be built with sturdy material to withstand the hardest recoil possible. Again, you will be shooting in the rain or at least in some sort of rough weather. The scopes need to be weatherproof and fog proof.

Choose the scope under $400 that has a rugged finish and is built with aircraft-grade aluminum, at least with some decent material.

Precision Power

You are using scopes to enhance your shooting skill and target acquisition. Precision power is the combined output of all the features of any optics. Magnification, clarity of lenses, objective lens size, etc. all contribute to the precision power. To acquire the maximum precision possible, you need to choose a decent rifle scope under $400.


Choice of the riflescopes will vary depending on your shooting range. Scopes that are perfect for mid-range shooting are not good for long-range shooting. So, you have to choose according to your shooting range.

For mid-range shooting, you will need a stable and accurate scope that features a fast zero-reset feature. And larger magnification is not a must in this case. And if you are planning to cover a long distance, you must go for the one with larger magnification.


Reticles are the crosshair of your scope. Reticles have different types. And you should choose depending on your shooting range. If you are a mid-range shooter you will move a lot, hence, BDC (bullet drop compensator) reticle can be the perfect choice for you. They are designed for mid-range and only work with guns that have a complementary design. Similarly, long-range shooters need reticle other than BDC ones.

Field of View

Field of view is the area that is visible to your eyes through any scope. So, a larger FOV means better visibility. Whether you will shoot in low light or daytime, a wider field of view will make your task easier and more enjoyable. That’s why you should consider this feature quite seriously.

Eye Relief

Eye relief refers to the distance that you should maintain between your eyes and the optics to have clear visibility. With the magnification, the eye relief will change. Therefore, you should choose a rifle scope under $400 that has decent eye relief. Shorter or longer eye relief than your necessity will make the shooting experience painful.


Sometimes shooters may forget to check this aspect since they are too busy with other features. But you should never neglect the weight of the scope. As you have to carry the rifle and scope, a lightweight combination will ease the task. On the other hand, a heavy rifle along with a scope will make target acquisition difficult for you. So, you should try to find a scope that is lightweight and can meet your requirements perfectly. A combination of scope and rifle like the henry 44 magnum can be the best option.

Elevation and Windage Adjustments

Elevation and windage correction options are the two most important adjustments that you will need very often. Without adjusting them correctly, you can’t acquire the target. Some scopes have fingertip features for those adjustments and others not. You should choose one that allows you easily adjust them.

Light Transmission

Light transmission is the combined result of the lens, coating, overall construction, and so on. Quality riflescopes assure perfect light transmission to provide you the best visibility. And better visibility will result in perfect shooting or hunting wild animals like coyotes with scopes. Some scopes clearly say about their light transmission. You should check about it before buying one.
