Are you confused about whether to use a red dot sight or a scope for your trusty AR-15? Well, you’re not alone. While both options may seem interchangeable at first glance, they each have their own unique advantages that can make all the difference in your shooting experience.
So, whether you’re a seasoned pro or just starting out, sit tight as we explore the different expectations to have when you choose between red dot sights and scopes and also help you find the perfect fit for your needs.
Overview of the AR-15
The AR-15 is a lightweight, semi-automatic rifle that is popular among hunters, target shooters, and law enforcement. It is highly customizable with a variety of optics and accessories available to suit the user’s needs.
When choosing a red dot or scope for an AR-15, consider budget, intended use, and dot size. Top-of-the-line options include Aimpoint ACRO and Holosun 509T while budget options include HS407C and DeltaPoint Pro. Offset red dot sights depend on personal preference and LPVO mounted on rifle may not be needed for 3-15x scopes.
Additionally, consider the size of dot when choosing a red dot sight; larger ones are easier to see but obscure targets, while smaller ones are more precise but harder to find quickly. Window size is also important — larger sizes have a better view of the target but are harder to keep the dot centered while smaller ones are easier to keep centered but have less view of the target area in smaller optics.
Pros and Cons of Red Dot Sights
Red dot sights are a popular choice for many AR-15 owners due to their versatility, accuracy, and ease of use. They offer a great way to improve your speed and accuracy when shooting. However, there are some pros and cons to consider when deciding if a red dot sight is right for you.
Pros:
Red dot sights provide a wide field of view, making it easier to acquire targets quickly. They also allow you to keep both eyes open while shooting, which can help with peripheral vision and target acquisition. Additionally, they are lightweight and compact, making them easy to mount on an AR-15.
Cons:
Astigmatism can cause trouble seeing clearly at night, so if you suffer from this condition you may want to opt for a flash hider or prism scope instead. Additionally, red dot sights can be expensive depending on the model you choose, so budget should be taken into consideration when selecting one.
Pros and Cons of Scopes
When deciding whether to put a red dot or scope on an AR-15, it is important to consider all the pros and cons of each option. Scopes offer improved accuracy and more precise aiming capabilities, as well as magnification that can be adjusted to suit the shooter’s needs.
On the other hand, scopes are heavier than red dots and require more time to adjust and zero in. Ultimately, the decision between a red dot or scope depends on personal preference, budget, intended use, and dot size.
Scope Types
Fixed power scopes
Fixed power scopes have a single magnification level, such as 4x or 6x. They are often more rugged and durable than variable power scopes and may be less expensive. Fixed power scopes are a good option for shooters who only need to engage targets at one particular range.
Variable power scope
Variable power scopes allow the shooter to adjust the magnification level, such as from 3-9x or 4-12x. They are more versatile than fixed power scopes and can be used for a wider range of shooting applications. Variable power scopes may be more expensive than fixed power scopes and may not be as rugged.
First focal plane (FFP) scopes
FFP scopes allow the reticle to change size as the magnification level is adjusted. This means that the reticle can be used for range estimation and bullet drop compensation at any magnification level. FFP scopes are more expensive than second focal plane (SFP) scopes but may be more versatile.
Second focal plane (SFP) scopes
SFP scopes have a reticle that remains the same size regardless of the magnification level. This means that the reticle can only be used for range estimation and bullet-drop compensation at one particular magnification level. SFP scopes are less expensive than FFP scopes but may be less versatile.
Tactical scopes
Tactical scopes are designed for use in tactical or military applications. They may have features such as illuminated reticles, bullet drop compensation, and range estimation markings. Tactical scopes are often rugged and durable and may have a wider field of view than traditional hunting scopes.
Hunting scopes
Hunting scopes are designed for use in hunting applications. They may have features such as long eye relief, low-profile turrets, and a wide field of view. Hunting scopes may be less rugged than tactical scopes but are often more lightweight and compact.
Types of Red Dot Sights
Reflex sights
Reflex sights use a single, illuminated red dot or green dot reticle that is projected onto a small mirror or lens in the optic. The shooter looks through the lens and sees the dot superimposed on the target. Reflex sights are compact and lightweight, making them ideal for use on handguns and rifles.
Holographic sights
Holographic sights use a laser to project a holographic reticle onto a glass plate in the optic. The shooter looks through the plate and sees the reticle superimposed on the target. Holographic sights are similar to reflex sights in terms of size and weight, but may be more durable and resistant to shock.
Prism sights
Prism sights use a prism to reflect the reticle back to the shooter’s eye. They are more compact than traditional scopes but offer some magnification, usually in the range of 1-5x. Prism sights are a good option for shooters who need a little magnification but still want a lightweight and compact optic.
