Selecting the right AR tactical rifle scope is a crucial decision for any firearm enthusiast, whether you're a seasoned shooter, a law enforcement officer, or a military professional. As a trusted supplier of Ar Tactical Rifle Scopes, I understand the importance of making an informed choice. In this blog, I'll guide you through the key factors to consider when choosing an AR tactical rifle scope to ensure you find the perfect match for your needs.

Magnification

One of the first things to consider when choosing an AR tactical rifle scope is magnification. Magnification determines how close your target will appear through the scope. Higher magnification allows you to see distant targets more clearly, but it also reduces your field of view and can make it more difficult to track moving targets. Lower magnification, on the other hand, provides a wider field of view, making it easier to acquire and track targets quickly.

For tactical applications, a variable magnification scope is often the best choice. Variable magnification scopes allow you to adjust the magnification level based on the distance to your target and the shooting conditions. A common magnification range for AR tactical rifle scopes is 1-6x, 1-8x, or 1-10x. These scopes provide a good balance between close-range and long-range shooting capabilities.

Reticle

The reticle, also known as the crosshair, is another important factor to consider when choosing an AR tactical rifle scope. The reticle is used to aim at your target and provides a reference point for making adjustments to your aim. There are several types of reticles available, each with its own advantages and disadvantages.

  • Duplex Reticle: The duplex reticle is one of the most common types of reticles. It consists of a simple crosshair with thick outer lines and thin inner lines. The thick outer lines make it easy to acquire your target quickly, while the thin inner lines provide a more precise aiming point.
  • Mil-Dot Reticle: The mil-dot reticle is a popular choice for long-range shooting. It consists of a series of dots or hash marks placed at specific intervals on the reticle. These dots can be used to estimate the distance to your target, make windage and elevation adjustments, and measure the size of your target.
  • BDC Reticle: The BDC (Bullet Drop Compensator) reticle is designed to compensate for the bullet drop at different distances. It consists of a series of aiming points placed at specific distances on the reticle. These aiming points are calibrated for a specific bullet weight and muzzle velocity, allowing you to aim directly at your target without having to make any adjustments for bullet drop.
  • Illuminated Reticle: An illuminated reticle is a reticle that can be illuminated with a light source. This makes it easier to see the reticle in low-light conditions, such as at dawn, dusk, or at night. Illuminated reticles are available in a variety of colors, including red, green, and blue.

Objective Lens

The objective lens is the lens at the front of the scope. It determines the amount of light that enters the scope and affects the clarity and brightness of the image. A larger objective lens allows more light to enter the scope, resulting in a brighter and clearer image. However, a larger objective lens also makes the scope heavier and more bulky.

For tactical applications, a medium-sized objective lens is often the best choice. A common objective lens diameter for AR tactical rifle scopes is 30mm or 34mm. These lenses provide a good balance between light-gathering ability and portability.

Tube Diameter

The tube diameter refers to the diameter of the main body of the scope. A larger tube diameter allows for more internal adjustment range, which means you can make larger adjustments to your aim. It also provides more room for internal components, such as the erector tube and the adjustment turrets.

For tactical applications, a 30mm or 34mm tube diameter is often the best choice. These tube diameters provide a good balance between internal adjustment range and portability.

Adjustment Turrets

The adjustment turrets are used to make windage and elevation adjustments to your aim. Windage adjustments are used to move the point of impact left or right, while elevation adjustments are used to move the point of impact up or down.

There are two types of adjustment turrets: capped turrets and exposed turrets. Capped turrets are covered with a cap to protect them from accidental adjustment. Exposed turrets, on the other hand, are not covered with a cap and are more accessible for quick adjustments.

For tactical applications, exposed turrets are often the best choice. Exposed turrets allow you to make quick and easy adjustments to your aim without having to remove the caps. They are also more durable and less likely to be damaged by rough handling.

Eye Relief

Eye relief refers to the distance between your eye and the eyepiece of the scope when you have a full field of view. A longer eye relief is important for tactical shooting because it allows you to maintain a proper shooting position and reduces the risk of scope eye, which is a condition caused by the scope hitting your eye when the rifle recoils.

For AR tactical rifle scopes, a minimum eye relief of 3 inches is recommended. Some scopes offer even longer eye relief, up to 4 inches or more.

Durability

Tactical shooting can be rough on your equipment, so it's important to choose an AR tactical rifle scope that is durable and reliable. Look for scopes that are made from high-quality materials, such as aircraft-grade aluminum or magnesium alloy. These materials are lightweight, strong, and resistant to corrosion.

In addition, look for scopes that are waterproof, fogproof, and shockproof. Waterproof scopes are sealed to prevent water from entering the scope, which can damage the internal components. Fogproof scopes are filled with nitrogen or argon gas to prevent the internal lenses from fogging up in humid or cold conditions. Shockproof scopes are designed to withstand the recoil of the rifle without losing their zero.

Price

Price is always a consideration when choosing an AR tactical rifle scope. AR tactical rifle scopes can range in price from a few hundred dollars to several thousand dollars. The price of a scope depends on several factors, including the magnification range, the type of reticle, the objective lens diameter, the tube diameter, and the brand.

While it's important to choose a scope that fits your budget, it's also important to remember that you get what you pay for. A high-quality AR tactical rifle scope is an investment that will last for many years and provide you with reliable performance.
