Get ready to dive into the world of optics and discover how to enhance your AR-15’s capabilities.
Understanding AR-15 Scope Fundamentals
The world of AR-15 scopes can seem vast, but understanding the basics is crucial to finding the right fit. Let’s break down the different scope categories and some key terminology.
Exploring Scope Varieties
First, let’s discuss the types of scopes available. Each type caters to specific shooting needs and preferences.
Red dot sights provide a simple and efficient aiming solution. They project a small illuminated dot onto the lens, allowing for rapid target acquisition. These are particularly well-suited for close-quarters combat situations or scenarios requiring fast target engagement. One primary advantage of a red dot is its compact size and lightweight design, making them easy to mount and carry. Because they lack magnification, they excel in scenarios where immediate situational awareness is paramount. However, red dots are not always ideal for longer-range shooting. The lack of magnification limits precision at extended distances.
Holographic sights offer a similar function to red dots but utilize a different technology. They project a holographic reticle, often in the form of a circle or other shape, onto the lens. This technology often provides a wider field of view and can be perceived to have less parallax than red dots. Parallax refers to the apparent shift of the reticle in relation to the target, and minimizing it increases accuracy. Like red dots, holographic sights are excellent for fast target acquisition at close to medium ranges. While they are often considered superior in terms of field of view and potentially less parallax, they can be more expensive than red dots and can sometimes be bulkier.
Low power variable optics (LPVOs) are increasingly popular for AR-15 rifles because of their versatility. These scopes offer variable magnification, typically ranging from 1x to 4x, 6x, or even 8x. This allows shooters to engage targets at close range (using the 1x setting) as well as at intermediate distances (using higher magnification). The ability to switch between magnification levels makes LPVOs ideal for general-purpose use, home defense, and tactical applications. However, compared to red dots, LPVOs can be more complex and heavier.
Rifle scopes with higher magnification levels offer the greatest precision for long-range shooting. These scopes typically have a fixed or variable magnification higher than what is commonly seen on an LPVO. They are often used for hunting, target shooting, and other applications that prioritize accuracy at greater distances. While offering excellent clarity and the ability to see small details, higher magnification scopes can limit your situational awareness at close ranges. These scopes also tend to be larger and heavier than other options.
Deciphering Magnification
Magnification, expressed in numbers such as 1-4x or 3-9x, indicates how much closer the target appears to the shooter. A 1x magnification means no magnification, providing a true view of the target. Higher magnification numbers, like 3x or 9x, bring the target closer. It’s important to match the magnification with the intended use of the AR-15. For instance, close-quarters scenarios benefit from low or no magnification for rapid target acquisition. Conversely, longer-range shooting demands higher magnification for precision. Consider your primary uses to guide your magnification selection.
Understanding Reticles
A reticle is the aiming point within the scope’s field of view. Several reticle designs exist, and each has specific advantages. Common reticle types include the duplex, BDC (Bullet Drop Compensation), Mil-Dot, and MOA reticles. A duplex reticle has thick outer posts that taper into a fine crosshair or point in the center. A BDC reticle uses markings to help compensate for bullet drop at various distances. The Mil-Dot reticle uses small dots for range estimation and holdover, whereas an MOA reticle utilizes minute of angle measurements. Select a reticle that aligns with your shooting style and the distances you typically engage targets.
Considering Objective Lens Diameter
The objective lens, located at the front of the scope, affects the amount of light that enters the scope. A larger objective lens diameter collects more light, resulting in a brighter and clearer image, especially in low-light conditions. However, a larger objective lens also increases the scope’s size and weight. The trade-off between light-gathering ability and scope size should be considered when making your choice. For hunting or shooting in dim environments, a larger objective lens may be beneficial. For lighter and more compact setups, a smaller objective lens might be preferred.
Key Features to Consider When Choosing an AR-15 Scope
Beyond the basics, several features will significantly impact your overall experience. Careful consideration of these elements is critical to making the right choice.
Determining Your Intended Use
The intended use of your AR-15 is the most significant factor influencing scope selection. If you are using it for home defense, speed and close-range accuracy are top priorities. A red dot sight or a low power variable optic (LPVO) would likely be the best choice. For hunting, magnification, a suitable reticle (like a BDC), and rugged construction are crucial. When target shooting, precision, clarity, and higher magnification take precedence. Those engaging in tactical or duty applications will likely want durability, reliability, and fast target acquisition, even if the budget is higher.
Setting a Budget
Setting a budget early in the process is a smart way to narrow your choices. Scopes range in price from relatively inexpensive to very costly. The quality of optics, materials, and features often correlates with the price. Decide how much you are willing to spend, and then explore the market within that range. Do not be afraid to invest in better glass if possible as that is an important factor, though the features you need also matter.
Focusing on Durability and Reliability
Your scope must be able to withstand the rigors of its intended use. Look for features like a waterproof, fog-proof, and shock-resistant construction. The materials used, and the overall build quality, will directly impact the scope’s reliability. Scopes designed for military or tactical applications are often built with exceptional durability.
Analyzing the Mounting System
The mounting system securely attaches the scope to your AR-15. Choose between scope rings and one-piece mounts. The height of the mount can also be important if you want to be able to co-witness with iron sights, this means you will still be able to use your iron sights, even with the scope on. The material of the mount (steel or aluminum) will affect its durability and weight.
Adjustments and Features
Elevation and windage adjustments allow you to fine-tune the scope’s point of impact. Consider the types of turrets, such as capped turrets, exposed turrets, or tactical turrets. Exposed tactical turrets often have easier access to adjustments in the field. Also, look for other features like illumination, which can be very helpful in low-light situations.
Examining Field of View
Field of view (FOV) is the width of the scene you can see through the scope at a given distance. A wider field of view is very advantageous, especially at lower magnifications, as it allows you to acquire and track targets more easily. It’s important for situational awareness, especially in dynamic environments.
Assessing Eye Relief
Eye relief is the distance between your eye and the scope’s eyepiece where you can see a full, clear image. Sufficient eye relief prevents “scope bite” (the recoil impact hitting your eyebrow). Longer eye relief is very important for high-recoil rifles.
Recommendations for Excellent Scopes
Let’s examine some specific scope models, broken down by category, as examples.
Several red dot sights are highly regarded for their quality and durability. The Aimpoint PRO, the Trijicon MRO, and the Sig Sauer Romeo5 are excellent choices. These red dot sights all offer reliable performance, robust construction, and fast target acquisition, making them good choices.
For holographic sights, the EOTech EXPS series is frequently praised for its wide field of view and fast target acquisition. These sights, like other holographic scopes, offer a distinct advantage in dynamic shooting environments.
The low power variable optic category offers considerable flexibility. The Vortex Strike Eagle, the Primary Arms 1-6x or 1-8x scopes, and the Sig Sauer Tango-MSR are popular options that offer great value. These scopes are suitable for various applications, including home defense, hunting, and general-purpose use.
For longer-range precision and target shooting, rifle scopes with higher magnification are the best choice. Leupold, Nightforce, and Bushnell offer excellent rifle scopes. Leupold’s VX-Freedom line provides a good balance of quality and value. Nightforce is known for its exceptional durability and performance. Bushnell’s Match Pro series is designed with competition shooting in mind.
Mounting and Zeroing Your Scope: A Quick Guide
Once you have a scope, you need to mount and zero it. Here’s a simple overview of the procedures.
First, ensure that the mounting system is compatible with your AR-15’s rail system. Follow the manufacturer’s instructions to securely attach the scope to your rifle. Then, you must “zero” your scope, which means adjusting it so that your point of impact aligns with your point of aim at a specific distance. Boresighting, a process of visually aligning the scope with the bore of the barrel, can help with the initial zeroing process. Then you can proceed with test shots and adjustment to get the scope perfectly zeroed for your preferred range.
Maintenance and Care for Your Scope
Regular maintenance ensures your scope performs optimally.
Regularly clean the scope’s lenses with a lens cleaning solution and a microfiber cloth to remove dust, dirt, and fingerprints. Store your scope in a cool, dry place when not in use. Protect it from extreme temperatures and direct sunlight. For scopes with illuminated reticles, monitor the battery life and replace the batteries when necessary.
Conclusion: Choosing the Right Scope
Selecting the right scope for your AR-15 is a crucial decision. It directly impacts your rifle’s performance and how well you can use it for your specific goals. Carefully consider the scope types, magnification, and features that align with your needs and budget. Thoroughly researching your options, considering the factors discussed in this guide, and choosing a scope that best fits your shooting style, will significantly enhance your experience.
