Buyer’s Guide

AR-556 scopes play a crucial role in enhancing accuracy and flexibility for AR-15 rifles chambered in 5.56mm NATO. When choosing the right scope, several key factors come into play, from optical performance and ergonomic design to durability and mounting options.

Optical Performance

Begin by considering the scope’s magnification range, typically expressed as power (e. g. , 1-6x24). Higher power settings offer greater zoom capabilities but may reduce light transmission through the lens. The exit pupil, calculated by dividing the objective lens diameter by the magnification, affects low-light performance – a larger exit pupil allows more light into your eyes.

Ergonomics and Mounting

The scope should feature adjustable objective (AO) and windage/elevation turrets for precise targeting adjustments. Note the click value of these turrets; smaller increments provide finer adjustments but may be more challenging to operate. The scope’s length of pull (distance between the eye and rear of the scope) should match your shooting stance for optimal balance.

Durability and Environmental Protection

AR-556 scopes deployed in various environments require different levels of protection. Look for waterproof, fogproof, and shock-resistant designs. Higher durability ratings, such as Mil-Spec 810G standards, ensure the scope can withstand harsh conditions. Premium coatings on lenses and tube walls prevent scratches and maintain optical clarity.

Parallax Adjustment and Zeroing

Proper parallax adjustment compensates for eye relief variation, ensuring consistent point-of-impact at different distances. High-end scopes offer electronic parallax correction, automatically adjusting focus for all distances beyond a set limit. Understanding your scope’s zeroing requirements helps maintain accuracy across multiple firearm platforms.

FAQ

What is an AR-556 scope?

The AR-556 scope refers to a specific optical sighting system designed for the 5.56 NATO cartridge. These scopes combine magnification capabilities with ballistic compensation features tailored for modern military and tactical rifles chambered in 5.56.

They incorporate advanced materials and coatings for durability and optical performance in various environmental conditions.

What are the key features of AR-556 scopes?

Key features include adjustable elevation and windage knobs, illuminated reticle options, and weather-resistant construction. Most scopes offer ballistic compensation settings for different ammunition loads and barrel lengths, optimizing point of impact for various shooting scenarios.

These scopes often include features like first and second focal plane reticles, tactical turrets, and parallax adjustment. The optical systems typically use multiple lens elements with anti-reflective coatings to minimize chromatic aberration and maintain clear, crisp images across the entire field of view.

What caliber is the AR-556 scope designed for?

AR-556 scopes are specifically engineered for the 5.56 NATO cartridge, providing optimized ballistics, elevation, and windage adjustments for this round. They are not suitable for other calibers and may not perform as intended with different ammunition types.

The scope’s tube diameter and objective lens size are optimized for 5.56 ammunition, ensuring proper light transmission and accurate ballistics calculations. Users should verify their scope’s specifications are compatible with 5.56 loads before purchase.

How do AR-556 scopes handle different ammunition loads?

AR-556 scopes are designed to accommodate various 5.56 ammunition loads, including subsonic, standard velocity, and high-velocity rounds. The scope’s ballistics adjustments and zeroing procedures account for differences in cartridge performance parameters.

Users should refer to their scope manual for recommended adjustments when switching between load types. Proper zeroing and understanding of each load’s ballistic characteristics is essential for consistent accuracy with different 5.56 ammunition selections.

What maintenance requirements do AR-556 scopes have?

AR-556 scopes generally require regular maintenance including lens cleaning, reticle inspection, and protective coating evaluation. The scope should be cleaned according to the manufacturer’s recommendations, typically using appropriate cleaning solutions and microfiber cloths.

Users should check the objective lens and eyepiece for proper alignment, inspect the reticle for wear, and verify all controls function smoothly. Regular lubrication of moving parts and tightening of retention screws ensures optimal performance and longevity.

What are the most common installation requirements?

Cheap or poorly machined barrels may cause issues with scope mounting rings, requiring special care during installation. Users should verify their barrel has a proper 1:7 or 1:8 rifling twist rate for 5.56 ammunition.

Installation typically requires a scope base or ring system compatible with the scope’s 30mm tube diameter. Proper alignment of the scope with the receiver’s mounting points is crucial for optimal performance and safety.
