{TOP 7} Best Scope and Red Dot Combo for AR-15 Reviews (2023)

Best Scope and Red Dot Combo for AR-15

There are several scopes on the market, each with a distinguishing feature that makes it stand out from the crowd. The issue with riflescopes is that they usually have specific applications where they work best. For example, a long range scope is not an excellent optic for close-range shooting and vice versa. Because of this, most gun owners have to purchase numerous scopes that can satisfy the different shooting applications. One of the answers to this problem of getting multiple scopes is having a riflescope and a red dot combination.

In this article, we’ll look at some preferred red dot optics that can be combined with regular scopes and fit perfectly on the most common weapons, such as the AR 15 rifle. Before the end of this scope review, you should have found out which scope and red dot combo is the best buy for you.  

Why use a Red Dot and a Scope Combo?

Red dot sights mounted to riflescopes are commonly used by IPSC participants. This optic combination has grown in popularity over the years as more shooters and hunters recognize its benefits.

If the distance between a shooter and the target is very close, a red dot sight is the ideal optical tool. Because these helpful instruments have a magnification power of only 1x, you may use them even when you have both eyes open. The 1x magnification makes the field of vision substantially larger than that of riflescopes. Having a red dot sight mounted onto a riflescope is less expensive than purchasing two separate mounting systems.

When firing at 50 m from the target or closer, you have to use a red dot sight for best results. However, if your target is far away, you need to use a riflescope.

When a target is around 20 meters, a red dot sight can be very helpful. Riflescopes are not always the simplest to use for precise aiming in a short distance. By combining the benefits of these two optical gadgets, you’ll have a well-equipped tool for any hunting situation.

The Benefits and Drawbacks of a Scope and a Red Dot Sight

The Benefits of Red Dot Sights

The Benefits of Red Dot Sights

A Red dot sight is an excellent optical instrument for acquiring targets quickly at short ranges. These compact gadgets have a 1x magnification and allow the shooter to aim with both eyes. The field of vision is substantially larger than scopes due to the 1x magnification and thin coating of material that holds the lens.

With the aforementioned properties, a red dot allows the shooter to watch the movement of many animals at the same time. Because these optics are mainly utilized during the daytime, the illumination can be tuned to a brightness appropriate to outdoor lighting. The eye relief is infinite, which means that the shooter’s eye doesn’t have to be in a certain position to clearly see the dot. Lastly, red dots have no parallax, which means the aiming point is always on the target regardless of where the shooter’s eye is positioned.

The Benefits of a Rifle Scope

The Benefits of a Rifle Scope

A Rifle scope is an essential tool for a precise shot. They enlarge pictures at a variable or fixed magnification, allowing for a detailed examination of a target. To make an ethical shot, a shooter must first check whether the animal is fit for harvest – at long distances, and this can only be achievable with some magnification. Most modern riflescopes include variable magnification, which allows the operator to modify magnification depending on the target’s distance.

Riflescopes, particularly those with large objective lenses (like 56 mm), performs admirably in low light. There are also night vision scopes that can be used for night shooting. Aiming at an animal from 150 meters away with a red dot will not yield results. Riflescopes that have an illuminated reticle often provide better illumination than red dots. With higher magnification scopes, the shooter can make parallax adjustments so that the image stays in focus at that given distance. This method achieves high precision, especially when shooting at distances greater than 200m.

Benefits of The Red Dot and Riflescope Combo 

The advantages of a red dot placed on a riflescope are now easier since we’ve discussed the merits of both optical systems. If your target is less than 50 meters, use a red dot; if it is further away, use a riflescope. A red dot is very beneficial when your target is 20 meters away, and it would be difficult to aim with a riflescope at that distance.
With this configuration, you get the benefits of both optics, which means you’re ready for any hunting circumstance. Mounting a red dot on a scope is a less expensive option than acquiring two separate mounting options. Many shooters are skeptical of mount manufacturers’ claims of 100% repeatability. Such folks prefer fixed mounting options; in this configuration, both the scope rings and red dot mount rings are fixed.

Disadvantages of Combined usage 

There are various drawbacks to this configuration.
Some may object to the bulkiness, claiming that a combo is unappealing to the eye and heavy. To some, it is more comfortable to use a red dot on its own, but if you require magnification, switching between the two would take too long, even if the scope mounts are detachable.

Solutions for Mounting Red Dots

There are two possible ways of attaching a red dot on a scope. It may be installed on top of the scope or at an angle of 45°. IPSC shooters like to install their red dot on the side because 223 rifles create less recoil; thus, the shooter doesn’t have to squeeze the butt of the rifle on his shoulder in an optimum way when taking a shot. Both configurations are feasible for hunters, but a red dot on top of a riflescope is far more convenient for hunters. With this setup, you just elevate your head to gaze through the red dot without moving the butt of your rifle from its position.

Why is a Scope and  Red Dot Combo Useful?

For hunters, this combo is useful when hunting in sparse and dense forested areas. The riflescope will allow the hunter to take a shot from 100meters upward in a sparsely forested area. Even so, in areas with few trees, a hunter will require magnification to inspect the game before firing.

A riflescope and red dot combo allow the hunter to have more time to choose the animal they want to shoot. When an animal is coming from a densely forested direction, it is difficult to see or aim until it is very close to the hunter. In these scenarios, a red dot is beneficial because it allows the shooter to aim at the animal even when it is 10 or 20meters away. When the target is this close, you’ll need fast target acquisition. The red dot’s 1x magnification, unlimited eye relief, and lighted dot can help you do exactly that.

The best red dot and scope combo for the Ar-15: Things to consider before purchasing

Now it is time to walk you through a well-researched shopping guide, which contains all of the criteria you will need to locate the ideal Red Dot and Scope Combo for your Ar-15.


If you are concerned about the product’s quality, make sure you look into its certifications or compliances. A product certification assures that the production methods have been followed and the quality is regulated in accordance with the standards. High-quality products are more durable. You should also buy a long-lasting product to avoid the headaches of fixing or replacing it. And it may prove to be cost-effective in the long term.


This is another reason people buy an optic. The main thing to remember here is that you must evaluate the product features to ensure that they are truly aligned with your need. Some optics have an excessive number of features, most of which are unnecessary. So why buy something that isn’t going to help you? Be explicit in your needs, and you will find the best product for you. 

Price Comparison

When looking for the greatest Scope And Red Dot For Ar 15, price comparison is essential. We frequently stress cost comparison charts since they allow you to compare rates from various providers. A chart like this might help you make an informed purchasing decision and get the greatest value for your money.

Comparing costs will help you select the most competitive alternative because it is crucial to balance cost with other variables such as features, quality, and convenience.

After-Sales Support

After completing your first purchase, you may require after-sales assistance for a variety of reasons. Such as mounting instructions. As a result, ensure that your product’s maker or vendor delivers excellent after-sales care. If you are happy with the after-sales service, you will be a satisfied client. That is why a product will earn the worst ratings if they lack a responsive after-sales support team.


Although warranty is an indication of a trustworthy optic, many decent optics are not covered by a warranty. However, if you have two options, one covered and another not covered, you must choose the one with a warranty. It assures that there will be a replacement or repair if your optics get damaged in accordance with the provisions of the policy. Some suppliers even have a money-back guarantee if the optics does not meet your expectations within a certain time frame.

Features Of A Good Red Dot and Scope Combo 

Finding a scope and red dot combination may be difficult for most people. This guide will help to ensure you make the best choice. We’ll look at the most important features and the reason you need them. When making a choice, it is critical to consider some features. Red dot and scope combos are not made equal; there is usually some feature or distinction that makes one stands out from the crowd. Let’s start with some features:

Windage and Elevation 

Windage and elevation adjustments are critical in any scope. That is because you need to be able to make corrections if the shot appears to be going off. The turrets make things as simple as possible; just turn the knob as needed.


If you need to spot a target that is far away, magnification is essential. However, magnification is not a standalone property of red dot optics; it is possible with the help of a magnifier. So whether you want to aim with a red dot with a magnifier or a regular scope with variable magnification, you can always sight far-distance targets. 

Objective Lens

The objective lens size will influence your choice of scope. When glancing through a scope, larger objectives will offer you plenty of space. Similarly, a smaller target will have fewer. Remember that bigger objective lenses would allow more light to pass through it. If you’re a hunter who starts hunting at dawn and desires better image quality in low-light settings, this might be a helpful feature.


Regular scopes do not need power the majority of the time; however, red dot sights need a battery to function. You may need to purchase additional batteries. Even though batteries are supplied out of the box, it is smart to always have extra batteries.

Reticle size and type

Another factor to consider is the reticle size and type. Reticle designs include chevrons, dots, and other patterns. The sizes vary, but a reticle with a size of 2 MOA or below will not be easy to use and may make an accurate shot impossible. Large dots might be difficult to hit if you want to make accurate shots. The MOA range of an optic can range from 2 MOA to 12 MOA. 

Best Scope and Red Dot Combo for AR-15

1. Trijicon ACOG Optic

The Trijicon ACOG is the best rifle scope and red dot sight combo on our list. This scope is highly sophisticated and made of technologically advanced equipment.

Furthermore, the reticle on the ACOG is an engraved crosshair .223 ballistic design that is ideal for close-range combat. This Trijicon Acog optic is suitable for close range to medium-range shots, thanks to the red dot sight on top of the scope and the fixed 4x powered optic. The bullet drop compensation, which can handle a 5.56 round, is one of the most important features in this Trijicon Acog riflescope and red dot combo.

Surprisingly, this AR 15 optic with an attached red dot has a lot of basic functions.

However, those features are actually one of the greatest you can get from a riflescope and red dot sight combination.

The Marine Corps deployed this ACOG ar 15 scope, which prompted a Congressional probe owing to the dramatically increased number of successful headshots. How can anyone be upset with such a result? If the US Marine’s results didn’t impress you, then the surprisingly pleasant regular features should win you over rather than turn you off. The Trijicon ar 15 scope and red dot combination are one of those scopes with a top-mounted red dot that is truly effective.

This scope is undoubtedly less expensive; thus, we would recommend replacing the red dot function if you meant to use this scope for a long time. If you cannot afford the $2000 top-of-the-line red dot sight for your rifle and you’re searching for a low-cost option, search no further than the NcStar scope.
