Holosun AEMS211301 AEMS Red Dot Sight, Black Anodized, 2 MOA Red Dot with 65 MOA Circle Reticle, 1.1 x 0.87

The Holosun AEMS red dot sight is a compact, lightweight optic built for shooters who want a wide field of view without the bulk of standard 20mm tube designs. At just 3.9 ounces and 11% shorter than conventional micro red dots, the AEMS delivers glass area and light transmission that punches well above its size—ideal for tactical rifles, competition builds, defensive setups, and hunters running lightweight AR platforms or pistol-optic carbines.

Inside that 7075-aluminum housing lives a 2 MOA red dot paired with a 65 MOA circle reticle, giving you precision aiming flexibility whether you're working distance or close quarters. The Solar Failsafe system keeps the reticle running in daylight without eating through batteries, while Shake Awake technology powers the optic down when it sits still and wakes it on motion—a feature that stretches battery life to an impressive 50,000 hours on alkaline power alone. You get Holosun's Multi-Reticle System, so you can dial in whichever aiming pattern works best for your rifle and task.

The AEMS ships with a removable lower 1/3 co-witness mount and clear flip-down lens covers, and that mount design lets you swap it across different platforms without fuss. Black anodize finish resists corrosion and glare, and the whole package is engineered to run hard without flinching.

Frequently Asked Questions

What's the field of view on the Holosun AEMS red dot?

The AEMS features a large field of view in a compact package—that's one of its core strengths compared to standard 20mm tube designs. It achieves this through its optimized glass surface area without adding weight or bulk.

What's included in the box?

The AEMS comes with a removable lower 1/3 co-witness mount and clear flip-down lens covers to protect the glass when not in use.

Will this mount work on different rifles?

Yes. The lower 1/3 co-witness mount is removable, allowing you to adapt the optic across multiple firearm platforms and mounting systems.

How does the battery last so long?

The AEMS combines three power-management features: Solar Failsafe harvests daylight to supplement battery use, Shake Awake powers the optic down during periods of inactivity, and the reticle itself is engineered for efficiency. Together, these deliver up to 50,000 hours of battery life.
