The Holosun AEMS Core Green (AEMS-120101) is an Advanced Enclosed Micro Sight built from durable aluminum that delivers a 2 MOA green dot reticle through a 1.1 x 0.87 inch window, giving you double the glass surface area of standard 20mm micro optics in a housing that runs up to 50,000 hours on a single CR2032 battery with Shake Awake motion activation. Designed for carbine shooters, duty rifle users, and competition builders who want a compact enclosed green dot sight for AR platforms and tactical builds with a large field of view and industry-leading battery life, the AEMS-120101 brings the same proven AEMS platform to shooters who prefer the 540nm green wavelength for faster eye acquisition in mixed lighting.

Special Features
- The 540nm green wavelength sits at the peak of human visual sensitivity, meaning your eye detects and locks onto the green dot faster than a red dot under the same lighting conditions, which translates directly to faster first-shot acquisition.
- The enclosed emitter design seals the LED and internal optics inside the aluminum housing, protecting the emitter from dust, debris, and direct moisture exposure that open-emitter designs leave unguarded on an unsuppressed or suppressed host.
- The window delivers double the glass surface area of standard 20mm micro optics while the housing sits 11 percent shorter overall, giving you a wider field of view and lower profile than competing micro designs of the same category.
- Shake Awake powers the sight on the instant the rifle moves and shuts it off after a selectable inactivity period, preserving battery life between sessions without requiring manual power management before a draw or range engagement.
- The last setting recall function brings the dot back at your previously used brightness level every time the sight activates, so your intensity setting is never wrong for your current environment after storage or transport.
- The side-load CR2032 battery tray uses a sealed, screw-retained design that allows a full battery swap without removing the sight from the mount or disturbing your established zero.
Practical Benefits
- The 2 night vision compatible brightness positions make the AEMS-120101 a capable optic for hunters and shooters who pair it with Gen I through Gen III night vision devices on a dedicated low-light or night hunting carbine build.
- The plus or minus 50 MOA adjustment range provides more windage and elevation latitude than most micro optics in this class, making the AEMS-120101 compatible with a wider range of mounting heights and host platform combinations.
- The lower one-third co-witness mount ships in the box and sets the dot at 1.63 inches, keeping your iron sights visible through the lower portion of the window without requiring a separate riser, adapter, or additional hardware purchase.
- The 3.9 oz weight keeps your carbine balanced and front-end light across extended range sessions, competition stages, and field carry situations where optic mass affects handling and fatigue over time.
- Your AEMS-120101 gives you a wide-window enclosed green dot with 50,000 hours of battery life and motion-activated power on a duty-ready carbine platform, so your rifle is always ready without manually switching the optic on or checking power levels before you head out.
The Holosun AEMS Core Green (AEMS-120101) with its 2 MOA green dot and oversized enclosed window is a dependable option for carbine shooters, competition builders, and duty rifle users who want a fast-acquisition green dot, rugged fully enclosed construction, and maximum battery life in a compact and lightweight micro sight package.
