10 Best AR 15 scopes 2025 in the United States

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.

The Leupold VX-5HD 3-15x44 CDS-ZL2 is a high-quality riflescope well suited for AR-15 owners who want versatility from close to longer-range shooting. Its magnification range of 3 to 15x allows for flexibility, making it good for both quick target acquisition and more precise shots. The 44mm objective lens, combined with Leupold’s high-definition lenses and Guard-ion coating, offers clear and bright images even in challenging weather, which is helpful for hunting or outdoor use.

The Impact-29 MOA reticle is placed in the second focal plane, meaning the reticle stays the same size as you zoom, which some shooters prefer for clarity but may require adjustments when estimating range at different magnifications. Eye relief is generous and the side focus parallax adjustment makes it easier to keep your target sharp from various shooting positions. A standout feature here is the CDS-ZL2 turret system, which provides two full revolutions of elevation adjustment and includes a push-button ZeroLock to prevent accidental changes. This customization, combined with Leupold’s option for laser-marked bullet-drop dials tailored to your specific ballistics, is great for serious shooters who want precision without fuss.

The scope is built tough with waterproof, fogproof, and shockproof construction, and backed by Leupold’s lifetime warranty, ensuring it can handle rough conditions and last for years. It weighs about 2 pounds, which might be a bit heavy for those looking for a lightweight option on their AR-15. Also, being a second focal plane scope, the reticle’s use at varying magnifications might not suit everyone. This scope is ideal for AR-15 users who value clear optics, ruggedness, and customizable elevation settings, especially for hunting or tactical use, but those wanting a lighter or first focal plane scope might consider other options.
