Adding a red dot sight to your hunting or shooting arsenal will improve your accuracy and speed. It will allow you to pin targets more efficiently and accurately than an iron sight, and many red dot sights are also more effective at improving speed and accuracy than some advanced magnified optics.

Our list of the 10 Best Red Dot Sights will help you identify which is best for the specific type of hunting or shooting you intend to do. Our Buyer’s Guide will also provide additional information about the most important factors to consider when shopping for a red dot sight.

Buyer’s Guide

To put it simply, a red dot sight is a mechanism that provides the shooter with a holographic red dot that assists in aiming. Within the mechanism, a red-light-emitting diode (LED) reflects off an angled piece of glass, which, in turn, emits a bright, focused red point wherever you’re aiming (4).

For beginning shooters, a red dot sight is a great way to accelerate your learning curve and shoot more accurately from the get-go. But when setting out to choose a red dot sight, make sure you consider the following factors: size, style, weapon and caliber, and battery type and life.

Size

Red dot sights come in a variety of sizes that are designed to fit with specific weapons. The red dot sight that’ll work best for your weapon will depend on the size and style of the weapon in question. More specifically, the available rail space on your weapon will dictate which red dot sights will be most compatible.

It’s important to keep in mind how much space your optics will use, as well as whether you want to use the optics with any additional accessories. You may quickly take up all available rail space with a larger optics on a smaller weapon, which rules out the possibility of adding other accessories.

Weight is also synonymous (in many cases) with size. Placing a heavy sight on a small weapon can render that weapon virtually useless for many scenarios. Always keep in mind that the ideal optics should enhance the efficacy of your weapon instead of taking away from its efficiency.

Style

There are two major styles of red dot sights: open or window-based designs and traditional, tube-like styles. Of the aforementioned sights above, Aimpoint (tube) and EOTech (open window) offer great examples of these distinct styles.

In general, the open window design is more compact and low profile than tube-style designs. The open window design also tends to offers a wider field of view because there is less to interfere with your vision, especially when using both eyes to aim. Additionally, open sights tend to be less bulky and lighter in weight.

In contrast, the tube-style design often provides more durability and protection for the optics it contains. Many tube-style sights are often more waterproof and capable of suffering more abuse than comparable open window designs.

Battery Type and Life

Battery type and life can vary incredibly between red dot sight manufacturers. One of the biggest issues that come with more exotic battery types is the availability of replacement batteries. CR123 batteries, for example, may not be available to you locally and can sometimes even be hard to find online.

It’s also important to consider the batteries that other shooting accessories utilize. If you’ll be using multiple accessories with your rifle or shotgun setups, it can be helpful to consolidate to a single battery source so that it’s easier to purchase replacements in bulk.

Longer battery life is, of course, desirable. However, competitive shooters will use their optics in a different manner than hunters, which means varying needs for battery life. In addition, optics that are put into use for military or law enforcement officials must come with batteries that offer outstanding life so that they keep the optics ready to use at a moment’s notice.

Frequently Asked Questions

A red dot sight is a common classification for a type of non-magnifying reflector (or reflex) sight for firearms, and other devices that require aiming, which gives the user an aimpoint in the form of an illuminated red dot (5).

A quality red dot sight will improve your ability to acquire targets quickly and hit them more accurately. Our list of Frequently Asked Questions will dive into some technical terms that apply to red dot optics and explore proper maintenance techniques.

What is ‘parallax’? 

The dictionary definition of parallax is ‘the effect whereby the position or direction of an object appears to differ when viewed from different positions.’ In our case, parallax refers to an optical illusion that must be corrected. It describes a situation where the focal plane of the object in the scope is offset from the reticle.

What is ‘MOA’?

A ‘Minute of Angle’ (MOA) is an angular measurement. One ‘MOA’ is equal to 1/60thof a degree and spreads about 1” per 100 yards. It’s important to recognize that 1 MOA is a different size at different distances. For example, 8” at 800 yards is still just 1 MOA.

What’s the best way to clean a red dot sight? 

When we talk about cleaning a red dot sight, we’re mainly referring to the lenses. For starters, it’s widely believed that you should never use Windex or similar glass cleaners, paper towels, or soap to clean the lens of a red dot sight. In fact, the most acceptable method for cleaning your red dot sight is by using a lens pen. If you don’t have immediate access to a lens pen, you can white vinegar on a Q-tip or a Q-tip wetted with alcohol.

What is a ‘lens pen’?

A ‘lens pen’ is a small, lightweight, pen-shaped cleaning tool that’s specifically designed for camera lenses and other optics items. Most featured a concave cleaning tip that’s especially suited to the lenses of rifle scopes and sights.

Summary

If you’re looking to improve speed and accuracy, it’s tough to argue against the benefits of a red dot sight for competitive shooters, hunters, and military or law enforcement officials alike.
