Our Top 5 Picks for Best Red Dot Sights

Red dot sights are the first optical upgrade most gun owners make. The sight’s popularity comes from a combination of low entry-level price and improved aiming ability. Any shotgun, rifle, or handgun sight that is an illuminated, non-magnified optical is known as a red dot sight.

Red dot sights incorporate several different technologies including fiber optics and holographic reticles. These sights use red, sometimes green, circles of various sizes. The dot, or chevron, aligns with the target aiming directly at the line of sight. This lining up of the gun to the target helps the user make the perfect shot.

Multiple layers of Tasco’s Rubicon finish fully coat the objective lens. This unique coating filters out harsh reds from the light spectrum making it suitable for bright daylight glare.

Even though the Rimfire is not waterproof certified, the assembly has an all-weather, matte finish for environmental hazards protection.

Red Dot Sight Benefits

Red Dot Sight BenefitsThe beginning shooter gets lots of shooting instructions thrown at them every day like, sight your target before touching the trigger.  Place your feet correctly while leaning forward slightly. Focus on the front sight and exhale to find a natural pause, and so on.

These instructions are all good, but when you add nervousness or a common fear of the recoil and muzzle blast, everything becomes overwhelming. For a new shooter to enjoy success and have some fun, it’s essential to make the process as simple as possible. Using a red dot sight is an excellent accessory for making the beginner’s life a little simpler.

Traditional methods have always leaned toward learning to shoot through iron sights before moving to advanced optics. However, modern thinking points toward teaching beginners to hit the target for a better and more enjoyable experience.

Science proves the brain learns from making the hit, not missing it and the red dot optic helps lessen the learning curve. Using a red dot optic makes the learning process positive and rewarding by helping the shooter hit early and often.

Five benefits of using a red dot scope are:

  • Wider field of view than most tube style sights
  • Faster and easier targeting
  • Greater accuracy rate
  • Unrestricted eye relief
  • Good low light operations

With the available red dot optic mounting solutions variety, you can attach one to most firearms. Whether you use a handgun, shotgun, or rifle, your shooting can benefit from attaching a red dot sight.

Red dot sights are durable, lightweight, and compact with simplistic operations, all for a moderate price. The biggest concern when it comes to red dot sights is determining the best one for your planned use and budget.

Features Considerations

There are many features to consider when choosing a red dot sight. However, there are four features we consider the most important when picking out your red dot sight.

  1. Housing Configuration
  2. Projection Type
  3. Reticle Style
  4. Red Dot Sight Battery Life

1. Housing Configuration

benefits of using a red dot scope Red dot sights come in two styles, tube or open style.

A tube style red dot sight looks very similar to a standard sight. Tube housing lets the shooter add protective covers and filters to the optic lens. These filters give you an advantage in bright sunlight that makes it easier to see the red dot when targeting.

Open style sights, do not have the classic tube style and consist of just the bare minimum basics. These basics include an objective window for sighting with a source of illumination. Since the open style has less room than the tube, you can’t add filters or protective lens covers.

2. Projection Type

With a red dot sight, you can choose from a reflex sight or holographic sight. The reflex sight projections are the most common projection found in red dots with recreation for their basic use.

Reflex sights reflect LED light, which is located behind the lens, and directs it into the shooter’s sightline. The objective lens is a partial mirror that prevents most of the light from passing through. When using a high-quality reflex sight, the lack of light is hardly noticeable. In the reflex sight, the reflective lens coating reflects only the light wavelength emitted by the reticle illumination system.

The holographic projection differs from the reflex sight in that the illumination comes from the front of the lens. In this setup, a laser diode light projects onto the viewing window and creates a holographic red dot. In simple terms, this means a laser light application takes a photograph of the reticle.

The hologram, sandwiched in the glass, forms a viewing window and assists the shooter with aiming at their target. In the field, the holographic and reflex sight have completely different technologies that are used for the same reasons.

3. Reticle Style

When you talk about the reticle, you’re referring to the red dot used for bringing the gun into line with a target. While all reticles illuminate for easier shooting in low light conditions, they aren’t always red or even a dot.

Since the red dot patterns and colors vary, you want to find the one the will allow you the most comfortable shooting experience. The optical patterns can range from one dot to crosshairs, or a bullseye pattern. Colors can also vary in red, green, blue or some sights give you a choice of all three in a single sight.

Higher end sights not only allow for different color adjustments but also have multiple dot pattern style choices. You can also adjust the reticle size to suit your targeting needs. Normally, the larger the dot, the faster the targeting.

We advise avoiding the fancy style red dot patterns. You want your eye naturally aligned with the reticle center. The fancy dot patterns distract the eye and can cause an extreme slowdown in acquiring the target.

4. Red Dot Sight Battery Life

Battery life might not come to mind when considering what red dot sight to buy. However, when you’re out in the field, you depend on the reticle showing up when you need it. If your battery has a short lifespan, you may lose the light when aiming at a target. If your reticle goes dark, targeting gets difficult, and accuracy suffers.

LED reflex sights use less battery energy than those using a holographic option. When choosing the best battery life, you want a scope that delivers at least one thousand hours constant on use. Preserve your battery life by turning the sight off whenever possible.

Cold weather shooting also affects the life of the battery. When using your sight during the winter, always carry a spare battery for backup. Having an extra battery on hand keeps you ready for anything.

Tips for Choosing a Red Dot Sight

Once you purchase your first AR-15 rifle, your next step is looking for an optical upgrade. The hard part of buying an optic is you get a ton of choices. A red dot scope that’s right for someone else might not be a good choice for you.

With all the styles and functions available, choosing is difficult. Here is a quick guide to help point you in the right direction based on your needs and budget.

Better Quality Doesn’t Always Come at a Higher Price

Just because a sight costs a lot doesn’t mean you’re getting higher quality with better features than the cheaper model. Advertising can draw you to an expensive red dot sight, but it’s missing some key features. A $500 sight may only have one pattern style with just one dot color. On the other hand, the $200 sight has two dot colors with three different pattern styles. Eye focus varies in each person.

Having a sight that you can change the reticle shape and color makes a huge difference in your shooting experience. This is where comparing apples to apples when it comes to features makes a big difference.

Gun Compatibility

All red dot sights are not always compatible with any gun. Manufacturers design specific sights to go with a certain type of gun which won’t work with others. Be sure the sight you are considering is compatible with the gun you plan to mount it on.

The Right Size and Weight Sight

When buying a sight, having the right size is as important as buying one that is compatible with the gun. The sight weight affects the gun weight which has a direct effect on using the gun. If the sight is too large or heavy, you can’t effectively handle the gun with the sight attached. Without good handling, it greatly diminishes the speed and accuracy of the shot.

Sight Mounting

You must accurately mount your new red dot sight. If the sight is even slightly off, it throws off your whole aim. Make sure the sight adapts to the right mounting system for your gun. Precise sight mounting helps you hit the target with each shot.

 Video Review


For those new to choosing an optical upgrade for their firearm, the red dot sight is an excellent choice. When you have an extremely accurate firearm, like the AR-15, you want to pair it with a top-quality aiming accessory.

The red dot sight turns your firearm into a formidable defense weapon with high-speed target acquisition and precise aiming. A red dot sight delivers far more accuracy and speed than a standard iron sight.

There are virtually hundreds of available red dot sights on the market. With the many choices, you must make careful consideration for choosing the best sight suited for your desired application.
