10 Best optics for AR 15s 2026 in the United States

The SIG SAUER Tango-MSR LPVO 1-6X24mm rifle scope is a strong contender for anyone looking to enhance their AR-15 with a reliable optic. Its 1-6x magnification range makes it versatile for both close and medium-range shooting, allowing for quick target acquisition and accurate shots. The 24mm objective lens provides clear and bright images, aided by low dispersion glass for excellent light transmission and optical clarity. This is particularly beneficial in various lighting conditions, further supported by the 11X brightness levels of the illuminated MSR BDC-6 reticle.

The scope is lightweight at 2 pounds, which is manageable for most users, and it comes with a robust aluminum construction that ensures durability. Its waterproof and fog-proof design, with nitrogen-purged internals and sealed housing, guarantees reliability in adverse weather conditions. One of its standout features is the integrated throw lever for rapid magnification adjustments, a useful addition for tactical and hunting scenarios.

However, the scope does not include night vision capabilities, which could be a drawback for users intending to operate in low-light environments without additional equipment. Additionally, while the second focal plane (SFP) design keeps reticle size constant, it might not be ideal for those who prefer the reticle to scale with magnification. In conclusion, the SIG SAUER Tango-MSR LPVO offers excellent performance for its price point, making it a valuable option for hunters and tactical shooters seeking a robust and versatile riflescope.

The Leupold DeltaPoint Pro Red Dot Sight is designed to provide optimal performance for AR-15 users. It features a 2.5 MOA dot reticle, which is ideal for quick target acquisition and accuracy. The Twilight Max Light Management System enhances this by improving light transmission, reducing glare, and increasing contrast and resolution, making it easier to see in low-light conditions.

This scope also includes Motion Sensor Technology to prolong battery life by deactivating the illuminated reticle when not in use and reactivating it upon movement detection. Constructed from durable aluminum and weighing only 1.92 ounces, the DeltaPoint Pro is lightweight yet robust, offering waterproof, fogproof, and shockproof capabilities. It is compatible with shotguns, handguns, and rifles, making it versatile for various firearms. Its integral mount ensures secure and straightforward attachment.

However, it does lack night vision capabilities, which might be a limitation for some users. Additionally, while its lightweight nature is a plus, it could mean less durability compared to heavier, more rugged scopes. Backed by Leupold's lifetime guarantee, this sight promises reliable performance and durability. Ideal for hunting and general shooting, it is a solid choice for those seeking a high-quality red dot sight for their AR-15.

The Trijicon ACOG 4x32 Scope is a well-regarded choice for AR-15 enthusiasts and those in need of a reliable combat optic.

Additionally, its rugged aluminum-alloy housing makes it exceptionally durable, capable of withstanding tough environments without losing functionality. The design allows for ‘both eyes open’ shooting, which is beneficial for quick target acquisition in close-quarters combat or hunting scenarios.

The scope offers a magnification of 4x, providing good clarity for medium-range shots. The bullet drop compensating reticle is calibrated for popular calibers like .223 and .308, allowing for accurate shooting up to 800 meters. This makes it a great option for users who want precision over long distances.

For serious shooters and military personnel, the Trijicon ACOG 4x32 Scope offers a robust, combat-proven optic that meets demanding requirements.
