Best Budget Red Dot for AR15 Reviews

Here is our list of the Best Red Dots for AR15 Under 100:

Bushnell Red Dot Sight Review

Bushnell Red Dot Sight

In our hunting endeavors over the years, we have used various Bushnell products. One feature, which we found common was ‘quality’. And, Bushnell TRS-25 Sight lives up to the Bushnell brand name. It has many features similar to Burris Fastfire III but at less than half the price. In fact, it is the best red dot sight for AR15 under 100 that we have ever used. 

Bushnell Trophy TRS is highly acclaimed and after learning about it, you would realize why. First is the user experience. Each feature contributes to delivering a great experience while you are shooting. Whether you are a highly experienced shooter with many years of practice, an avid hunter, or a newbie, Bushnell TRS-25 is likely to be the perfect fit for your AR15.

One of its top features is fast target acquisition even in low light conditions. The front lens is tinted amber to provide a bright contrast for fast target acquisition and accuracy. This feature is really helpful for hunters as it allows them to see their target even in the dim or fading light.

Bushnell TRS-25 provides a 3 MOA dot reticle which outperforms even a premium 2 MOA dot 3x the cost thanks to its parallax-free design. Due to its parallax-free design, the red reticle follows the eye movement and stays fixed on the target. This eliminates the need for centering.

It comes with 11 intensity levels for brightness settings. Higher the intensity, the higher the brightness level of the MOA dot. Yet, the MOA dot may appear blurry if the brightness intensity is set too high for the ambient light. It uses CR2032 battery. Bushnell claims up to 3,000 hours of battery life. During our review, we were able to log around 300 hours of battery life on Level 1 brightness.

How to Pick a Budget Red Dot

A red dot sight is a magnifying and targeting device that pairs with firearms to improve aim and precision. Red dots assist and by applying an aim point in the form of an MOA dot on a selected area or a pinpointed target.

Red dot sights provide more help and support than what most people generally assume. Although they are primarily a tool and accessory for firearms, red dots can be paired with cameras and telescopes as well.

Basically, the red or green dot sights are geared around aiming and scoping. They are a highly beneficial accessory for many products than just firearms. Red dots are a necessary add-on to improve one’s skill at shooting.

Speed and Accuracy

Compared to many other sights that can be attached to a gun or a camera, red dots offer a better experience. For example, they are far simpler to use when compared to iron sights. Similarly, they are more easily available.

Red dots may differentiate depending on the brand and specifications, but they all have one feature in common. When contrasted with iron sights, red dots offer increased speed for precise aimingThe way red dots operate and move to locate the intended target is amazing, especially in locating fast-moving targets.


Red dot sights also seem to have great reusability. Most red and green dots are versatile and can be connected to different equipment such as rifles, handguns, and shotguns. All these guns can benefit when paired with an MOA red dot sight, helping shooters greatly improve their range, accuracy, and speed.

Red dots prove to be a helpful tool and aid for experienced as well as new hunters. Most first time or inexperienced hunters that use even budget red dot sights have reported rapid accuracy improvements in a short span of time.

Experienced hunters will tell you that it takes perseverance and time to improve one’s focus. But red dot scopes can help you focus on targets easily and accurately, thus helping you shorten the learning curve.

Ease of Use

Most rifles are compatible with a range of sights, scopes and red dots. Obviously, you need to choose which of these can help you get a good sight and view of your intended target.

You may think you need an expensive scope for your rifle, but maybe you just really need a simple scope or a red dot sight. With the addition of a red dot optic, any shooting experience can be easily improved. Red Dots come with low magnification power, making them safer for inexperienced users.

The Best Red Dot Sights are a highly helpful accessory for different guns in many different ways. They are not only used by the first time or inexperienced shooters to practice and build up accuracy. The red dots can help experience shooters focus better as well.


All red dot optics are beneficial for improving shooting speed and accuracy. Still, it is important to understand their features to help differentiate among the different ones on the market.

Size and fitment should be the first thing to consider when buying a red dot sight. So it is important to consider one which would fit your selected firearm. Also, you should check whether your chosen scope is night vision compatible. It would allow you to see the dot even while using your night vision scope for AR15.

Another feature to consider when purchasing a red dot sight would be the battery life and power. Most electronic red dot sights are battery-powered, and the red dot reticle appears black when out of power. The MOA dot size also varies. For example, the 2 MOA dot covers around 2 inches at 100 yards.

Build quality and durability should also be considered when shopping for a red dot sight. As red dot scopes are mostly used outdoors during hunting, they should be able to withstand even rough conditions.
