10 Best optics for AR 15s 2025 in the United States

The HOLOSUN HS407C X2 Red 2 MOA Dot Open Reflex Sight is a solid choice for users looking for a high-performance reflex sight for their AR-15 or full-sized handgun. A notable strength is its 2 MOA dot reticle, which contributes to precise targeting. The 1x magnification ensures that your field of view remains large, aiding in quick target acquisition. Durability is a key selling point with its 7075 Aluminum housing and anodized surface finish, making it resilient to rough handling and harsh conditions.

The Shake Awake technology is quite beneficial as it helps extend battery life by powering down when not in use and instantly reactivating with movement. Another impressive feature is the Solar Failsafe, which ensures the sight remains operational with a backup solar power source if the battery fails. The HS407C X2 also offers unlimited eye relief, meaning you can use it comfortably at various distances without straining your eyes. However, at 1x magnification, it may not be suitable for long-range precision shooting that requires higher magnification.

The sight's light weight of 0.09 pounds makes it easy to handle without adding significant weight to your firearm. While it excels in many areas, potential users should note that it's specifically designed for close to medium-range use and might not meet the needs of those requiring long-range optics. Additionally, it is tailored more towards handguns, although it can be adapted for AR-15 rifles as well. In summary, this reflex sight is excellent for those seeking durability, ease of use, and reliable performance in varying light conditions, particularly in close to medium-range shooting scenarios.

The Holosun HS510C & HM3X Combo offers a versatile and durable optics solution for AR-15 users. Its standout feature is the advanced LED technology, providing up to 50,000 hours of use on a single CR2032 battery, which means less frequent battery changes. The magnifier that flips to the side allows you to switch between 1x and 3x magnification conveniently, making it adaptable for both close and mid-range shooting.

The reticle options are flexible, with a choice of a 65 MOA circle with a 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only, all switchable at the push of a button. This ensures you can customize your aiming preference without needing to re-zero the sight. The protective titanium alloy hood enhances durability, and the sight is waterproof up to a meter, making it suitable for various weather conditions.

At nearly 5 ounces, it might add a bit of weight to your setup, but the trade-off is robust durability. The included protective storage case is a nice addition for keeping the equipment safe when not in use. On the downside, the product’s package dimensions are relatively bulky, which might be a consideration for some users. This optics combo is ideal for shooters looking for a reliable, flexible, and durable sighting system with the added benefit of easy magnification adjustment.

The HOLOSUN HS510C Multi-Reticle Green Open Reflex Sight is a versatile and durable optic designed for AR-15 rifles and other long guns. It features a robust aluminum housing with a titanium hood, ensuring it can withstand heavy use and recoil. The sight offers a 1x magnification and a 30mm objective lens, which is ideal for quick target acquisition without magnification. The Multi-Reticle System (MRS) allows users to switch between a 2 MOA dot and a 65 MOA circle, which is helpful for both precision and quick targeting.

One of its standout features is the Shake Awake technology, which conserves battery life by turning off the LED when not in use and instantly reactivating it with the slightest movement. Additionally, the Solar Failsafe feature ensures the reticle remains visible even if the battery fails, adjusting brightness according to lighting conditions. The sight is parallax-free with unlimited eye relief, making it comfortable to use for extended periods. Its compact size (3.3 inches long, 1.8 inches wide, and 2.3 inches high) and lightweight design (0.52 pounds) add to its usability without adding significant weight to the firearm.

The sight lacks magnification, which might not be suitable for long-range shooting. Additionally, while it includes night vision-compatible brightness settings, the sight itself does not have night vision capabilities. Users will appreciate the limited lifetime warranty, and its compatibility with firearms using a 1913 Picatinny Rail makes it versatile. The HOLOSUN HS510C is a strong choice for AR-15 users looking for a reliable, durable, and feature-rich reflex sight for short to mid-range shooting.
