Holosun AEMS CORE Green Dot Sight - Black Anodized, 1.0 x 0.87, 2 MOA

The Holosun AEMS CORE green dot sight brings serious glass real estate to a micro-sized package built for shooters who refuse to compromise on field of view without the weight penalty. This compact 2 MOA green dot optic is engineered for modern sport rifles, defensive setups, and hunting rigs where you need fast target acquisition and peripheral vision without the bulk of traditional tube-style sights. At just 3.9 ounces and noticeably shorter than standard 20mm micro optics, the AEMS CORE proves you don't need a larger footprint to see more of the fight—or the game.

Built around a pressure-forged aluminum housing finished in black anodize, the AEMS CORE is designed to live hard on your rifle. The included lower 1/3 co-witness mount lets you use your iron sights as a backup and moves between platforms without swapping glass. IP67 waterproofing keeps internals dry whether you're running drills in the rain or hunting through weather. Shake Awake technology means your battery life lasts—Holosun rates the AEMS CORE at up to 50,000 hours on a single CR2032 lithium battery (included), turning your optic from a constant drain to a fire-and-forget piece of kit.

The oversized lens (1.0 x 0.87) is the AEMS CORE's standout advantage: double the glass surface area of conventional micro dots gives you a wider, brighter sight picture without requiring a heavier or taller chassis. The 2 MOA dot reticle keeps your target view uncluttered while delivering the precision for accurate shooting at distance. If you're building a rifle that needs a lightweight, dependable aiming solution with genuine optical advantages, the Holosun AEMS CORE delivers both.

Frequently Asked Questions

What rifles can I mount the AEMS CORE on?

The AEMS CORE mounts to any firearm with a standard Picatinny rail. The removable lower 1/3 co-witness mount adapts easily between rifles, and you can swap it to different platforms without removing the optic from its base.

Can I cowitness iron sights with the AEMS CORE?

Yes. The included lower 1/3 co-witness mount allows your iron sights to sit just below the green dot, giving you a backup aiming system and faster target reacquisition if needed.

How long does the battery last?

Holosun rates the AEMS CORE at up to 50,000 hours of runtime on a single CR2032 lithium battery. Shake Awake technology turns the sight off when it's not in use, conserving battery life when your rifle sits in the safe or on a truck mount.

How much does the AEMS CORE weigh?

The optic weighs 3.9 ounces without the mount, making it one of the lightest micro dot sights available. This minimal weight impact is a real advantage for hunters and sport shooters who count ounces.
