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 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.

The ATN Thor LTV is a thermal scope designed primarily for hunting and shooting in low-light or no-light conditions. It offers a useful magnification range of 5x to 15x, which covers most general hunting scenarios. The 160x120 thermal sensor with a 12-micron pixel size delivers clear thermal images, enhanced further by SharpIR technology for sharper, more detailed views. This is especially helpful for spotting animals in dense cover or total darkness. Eye relief is generous at 90mm, providing comfortable viewing without straining your eye, and the scope weighs about 1.4 pounds, making it light enough to mount on most rifles without affecting balance.
