Collimator AT3 Tactical Alpha 2 MOA Green

AT3 Tactical Alpha 2 MOA with Green Dot is AT3’s first reflex sight featuring a battery‑saving function (Shake Awake). This allows the sight to run on a single battery for many years. The model is affordably priced and highly versatile. It is compatible with rifles and carbines (AK, AR15) as well as shotguns. The package includes two mounts: Absolute Cowitness and Lower 1/3 Cowitness.

Versatile applications

The AT3 Tactical Alpha is designed for long‑gun platforms including AR15 and AK carbines, semi‑automatic shotguns and hunting rifles. The sight body is precision‑machined from 6061‑T6 aluminum. The unit is lightweight and rugged with the high Absolute Cowitness mount and weighs approximately 185 g. The model retains zero reliably even on large‑caliber .50 weapons and provides a true 1× view with no parallax, making it suitable for both sport shooting and hunting.

Robust construction

The AT3 Alpha uses multi‑layer anti‑reflection coatings on the lenses that are resistant to scratches and deliver bright, high‑contrast images. The sight has been recoil‑tested with calibers 5.56, .308, 12GA and maintained zero even under extreme conditions. It is certified to 800 g recoil rating and meets IPX7 water‑resistance standards (submersible to 1 m for 30 minutes). The tube is nitrogen‑filled to prevent internal fogging during rapid temperature changes.

Green aiming dot

The sight features a 2 MOA green dot, ideal for both dynamic and precision shooting. The dot has a total adjustment range of up to 70 MOA and is adjusted via exposed turrets with 0.5 MOA click value. Brightness includes 9 daytime settings plus 2 settings for night‑vision compatibility.

Up to 50,000 hours runtime on one battery

The sight offers an impressive runtime of over 50,000 hours on a single battery (roughly 6 years), thanks to the efficient LED and the Shake Awake system which powers the sight down after 15 minutes of inactivity and instantly wakes it when the weapon is moved.

Absolute Cowitness Riser Mount

The AT3 Tactical ships with a factory‑installed Absolute Cowitness Riser Mount (Cantilever) that moves the optic forward from the eye — making the dot faster to acquire and allowing co‑use of iron sights. With the Absolute Cowitness mount the dot aligns with the iron sight plane, so if the sight fails or the battery dies you can continue accurate fire without removing the optic.
