Holosun AEMS221301 Green Dot Sight - Black Anodized, 2 MOA Green Dot/65 MOA Circle Reticle, 1x Magnification

The Holosun AEMS221301 is a compact green dot sight designed for shooters who want genuine glass optics without the bulk of a full-size reflex. This black anodized unit packs double the glass surface area of standard 20mm red dots into a footprint that's 11% shorter and weighs just 3.9 ounces—ideal for AR platforms, pistol builds, shotguns, or any rifle where weight and sight picture matter. The 2 MOA green dot pairs with a 65 MOA circle reticle, giving you a sharp aiming point and a reference ring for rapid target acquisition.

Built around Holosun's proven green-dot technology, the AEMS221301 includes practical features that earn trust in the field: Solar Failsafe automatically switches to battery if ambient light drops, so you're never left without a reticle. Shake Awake motion detection wakes the sight only when you move it, conserving battery life to a rated 50,000 hours—more than five years of continuous use. The multi-reticle system lets you dial between the 2 MOA dot and 65 MOA circle depending on your shooting distance and preference. The removable lower 1/3 co-witness mount comes included and can be swapped out, letting you adapt the sight across multiple guns without buying new hardware.

Rugged 7075-T6 aluminum housing resists recoil shock and abuse. Removable flip-down lens covers protect glass when the sight isn't in use. No batteries are included, but the long battery life and solar backup mean you can mount it and shoot through seasons without worrying about the reticle dying at an inconvenient moment. For hunters, precision rifle shooters, and home defenders who want a compact, proven green dot, the AEMS221301 delivers field-proven reliability in a package that doesn't compromise sight radius or add unnecessary weight.
