10 Best AR scopes 2025 in the United States

The ATN Thor 5 LRF Smart HD Thermal Scope is a strong contender in the thermal scope category, particularly suited for hunters who want advanced features. One of its standout strengths is the Ultra Sensitive Next Gen Thermal Sensor, paired with a high-resolution OLED display that offers rich colors and detailed visibility, making it easier to spot targets in varying light conditions.

Magnification ranges from 4x to 16x, providing flexibility for both close and long-range shots, while the built-in Laser Rangefinder is a valuable addition for those who want to ensure precision at any distance. The Advanced Ballistic Calculator helps users make informed decisions about their shots, enhancing accuracy and reducing guesswork.

The ability to create custom reticles is a fun and unique feature, allowing users to personalize their shooting experience. Moreover, the scope includes HD video recording capabilities, enabling hunters to capture their adventures in great detail, which is perfect for sharing with friends or reliving successful hunts. However, the size and weight of the scope (2.1 pounds) may be cumbersome for some users, particularly during extended outings. The scope is also ITAR restricted, meaning it cannot be exported, which might limit its accessibility for some users. Lastly, with a price point typically associated with high-end thermal scopes, it may not be suitable for budget-conscious hunters. The ATN Thor 5 LRF Smart HD Thermal Scope is a high-quality option for serious hunters seeking advanced technology and functionality, although potential users should weigh its size, weight, and price against their specific needs.

The Vortex Crossfire II 4-12x44 riflescope is a solid choice for AR owners who want versatility for mid-range shooting and hunting. Its 4-12x magnification range offers flexibility, letting you zoom in for detailed shots or zoom out for a wider view. The 44mm objective lens provides a good balance, gathering enough light to give clear, bright images without making the scope too bulky. The Dead-Hold BDC reticle is designed to help estimate bullet drop at different distances, which is handy if you’re hunting or shooting at varying ranges without complex adjustments. With a field of view of about 24.7 feet at 100 yards, you get a decent sight picture that helps track moving targets. Eye relief is generous at over 115mm, making it comfortable and safe to use with rifles that have a bit more recoil or a heavier setup.

The scope’s construction is sturdy, using aircraft-grade aluminum with O-ring seals and nitrogen purging to keep water, dust, and fog out, so it can handle tough outdoor conditions well. One thing to keep in mind is that the reticle is not illuminated, and the scope doesn’t support night vision. Also, while it’s very durable and offers lifetime warranty coverage, the weight of around 17 ounces might be noticeable on lighter AR platforms.

This riflescope suits hunters and shooters who want a reliable, clear optic with useful range compensation features in a rugged package without extra high-tech complexity.

The Nightforce NX8 4-32x50mm F1 scope offers a very wide magnification range, from 4x to 32x, making it highly versatile for both close and long-distance shooting. This means you can quickly target fast-moving objects nearby or zoom in sharply on distant targets with excellent clarity. Its 50mm objective lens allows good light gathering for bright, clear images even in low light. The MIL-XT reticle is designed for precision, featuring clear markings that help with fast and accurate aiming, especially useful in competitive or hunting situations. The first focal plane reticle keeps the aiming marks accurate at all zoom levels, which is a valuable feature for shooters who adjust magnification often.

Eye relief is 3.5 inches, which is adequate but may feel a bit tight for some users, especially with higher recoil firearms. The scope’s field of view ranges from a wide 26.1 feet at 4x to a narrow 4.6 feet at 32x, which is typical for this magnification range but means you'll see less surroundings when zoomed in. Durability stands out, as the scope is built with a sturdy 30mm aluminum tube and weather-resistant features, suitable for harsh hunting conditions. It also includes helpful extras like flip-up lens covers and a power throw lever for quick zoom changes.

The main downsides are the relatively short eye relief and the scope’s length and weight, which might feel bulky for some shooters or certain rifle setups. This scope is a strong option for hunters and shooters seeking a reliable, sharp, and versatile AR scope that can handle varied shooting scenarios.
