10 Best AR 15 scopes 2026 in the United States

The Trijicon ACOG 4 x 32 Scope is a versatile and robust choice for those needing a reliable AR-15 scope. It features a magnification range from 3x to 4x, which is suitable for mid-range shooting. The objective lens diameter of 40mm ensures clear and bright images. One of its standout features is the tritium/fiber optic illuminated reticle that adjusts brightness based on available light, making it advantageous for various lighting conditions without needing batteries. The red Chevron ranging reticle aids in bullet drop compensation up to 800 meters, enhancing long-range accuracy, particularly when paired with the USMC's M16A4 weapon system.

The eye relief is relatively short at 1.5 inches, which might be less comfortable for some users, especially with powerful recoil. The rugged aluminum-alloy housing makes it extremely durable, a notable feature for combat or harsh environments. The scope employs the Bindon Aiming Concept, allowing for 'both eyes open' shooting, which can improve situational awareness in close-quarter combat situations.

While it does not feature night vision, this scope is highly rated by users for its reliability and performance in diverse conditions. It is relatively heavy at 2 pounds, which might add noticeable weight to the rifle. The product is well-regarded but comes at a premium price, reflecting its advanced features and durable build, making it a suitable choice for serious shooters and professionals in demanding environments.

The ATN Thor 5 LRF is a high-tech thermal scope designed to enhance shooting performance in low visibility conditions such as night or fog. It features a 4-16x magnification range suitable for various distances, and a 320x240 sensor resolution paired with a bright OLED display provides clear, detailed images with rich colors, making target spotting easier in any light. The built-in laser rangefinder (LRF) allows quick distance measurement to targets, improving shooting accuracy.

A notable feature is the advanced ballistic calculator that automatically adjusts aiming points based on environmental data, helping shooters achieve more precise shots without manual calculations. Users can customize and share reticles, adding both functionality and personalization. The scope also records HD video of hunts for later review or sharing.

However, the scope weighs over 2 pounds and is larger than typical AR-15 scopes, which may affect balance and handling on lighter rifles. The price and technical complexity might exceed the needs of casual shooters, and export restrictions limit its availability. For serious users focused on thermal imaging and precision shooting with an AR-15, the Thor 5 LRF provides advanced capabilities, while newcomers or budget-conscious users might find it more than necessary.

The ATN X-Sight 5 LRF is a digital smart scope designed for AR-15 rifles, offering a wide magnification range from 3x to 15x, which is versatile for both close and medium-range shooting. Its ultra HD 4K+ resolution delivers very clear images with vivid colors, making target identification easier during the day. One standout feature is its enhanced night vision mode, allowing you to see clearly in low light without extra equipment, which is great for hunting in dawn or dusk conditions. The scope includes multiple reticle options, so you can choose what best suits your shooting style. It also boasts a ballistic calculator built-in, which helps adjust for bullet drop and wind, potentially improving accuracy without manual calculations.

The eye relief and field of view are reasonable for this magnification range, but keep in mind it weighs 2.1 pounds, which is a bit heavier than typical AR-15 scopes, so it might affect the rifle's balance. Turrets and adjustments are digital and controlled through the device’s interface, which may appeal to users comfortable with technology but could be less intuitive for those who prefer traditional manual knobs. Additional features like video recording in 4K, Wi-Fi connectivity, and recoil-activated slow-motion video are unique perks, especially for users who want to capture their shooting sessions or stream live.

These smart features can also draw more battery power, though the scope offers a solid 14+ hours of use on a full charge. If you want a high-tech scope with day and night capabilities and integrated technology for hunting and shooting, this scope fits well. However, if you prefer a lightweight, straightforward scope with manual controls, this model might feel more complex and heavier than necessary.
