10 Best AR scopes 2025 in the United States

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 Trijicon ACOG 4 x 32 Scope USMC Rifle Combat Optic for A4 is a highly durable and combat-proven AR scope. Its magnification ranges from 3x to 4x, offering versatility for different shooting distances. The reticle is illuminated without a battery using tritium and fiber optics, which automatically adjusts based on light conditions, ensuring visibility at all times. The objective lens diameter is 40mm, providing a clear and bright field of view.

The eye relief is somewhat limited at 1.5 inches, which might be less comfortable for certain shooters, especially those requiring glasses or wanting a safer distance from recoil, but still within acceptable range for many users. The scope's rugged aluminum-alloy housing makes it almost indestructible, suitable for harsh combat environments. The bullet drop compensating and ranging reticles are specifically designed for the USMC's M16A4 weapon system, making it highly specialized for this type of rifle.

While it is not equipped with night vision, the scope’s performance in low light conditions is commendable due to the illuminated reticle. Users looking for a robust and reliable scope for combat or hunting will benefit most from this product, though those needing longer eye relief might need to consider alternative options.

The ZEISS LRP S3 6-36x56 First Focal Plane MOA Riflescope is designed for those passionate about long-range shooting and hunting. With a magnification range from 6x to 36x, it provides versatility whether you're aiming close or far. The 56mm objective lens and advanced optics, featuring Extra Low Dispersion (ED) glass and ZEISS T* multi-coated lenses, ensure a bright and clear view with impressive 90% light transmission. This means better performance in low light conditions, which is crucial for hunting at dawn or dusk.

The illuminated reticle, visible even in daylight, enhances accuracy with customizable red or green illumination options and five intensity levels, focusing on the center section for precision aiming. Additionally, the first focal plane design means that the reticle scales correctly with magnification, keeping your aim consistent at all ranges. One of the standout features is its total elevation travel of 110 MOA, making it excellent for extreme long-range adjustments. The Ballistic Stop provides a reliable return to zero, and the External Locking Windage Turret allows for quick and secure windage adjustments.

Durability is another strong point – with a 34mm main tube and a design that withstands up to 1,500 g-force shocks, it's built to last. However, weighing in at 39.1 ounces, it is on the heavier side, which might be a drawback for those looking to minimize added weight to their rifles. Despite the substantial investment, this riflescope offers a robust feature set for serious shooters and hunters.
