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 EOTECH EXPS3-0ODGRN is a holographic weapon sight designed to fit well on AR-15 rifles, especially for those looking for quick target acquisition and compatibility with night vision gear. Unlike traditional scopes with magnification, this sight offers a 68 MOA ring combined with a 1 MOA dot reticle, providing a clear aiming point without zooming in. This makes it great for close to mid-range shooting where speed and accuracy are key. The sight has a generous eye relief, so you don’t have to position your head perfectly to see the reticle clearly, which adds to comfort and faster aiming.

It mounts easily on common Weaver or Picatinny rails using a quick detach lever, saving time when switching between setups. The side button control is compact and doesn't take up much rail space, making it ideal if you want to add a magnifier later for longer shots. Its construction is sturdy aluminum, weighing just 11 ounces, so it won’t add much bulk to your rifle. Plus, it’s night vision compatible, which is a big bonus for low-light or tactical use.

Since it doesn’t have magnification, it’s not suited for long-range precision shooting. Also, while the reticle is excellent for fast target engagement, some users might prefer a traditional scope if zoom is important to them. The EOTECH EXPS3-0ODGRN is well-suited for hunters, competitive shooters, and tactical users who value quick, reliable aiming over magnification. Backed by a solid 10-year warranty, it’s a dependable choice if you want a high-quality holographic sight for your AR-15.

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.
