Aimpoint COA, 3.5 MOA Red Dot, A-CUT Interface, Enclosed Emitter, Black The Aimpoint COA is a 1X, non-magnifying red dot reflex sight with a 3.5 MOA aiming point, built for carry and duty pistols, with the option to run it on carbines, shotguns and rifles. This listing is Aimpoint part number PA000489, which mounts via the A-CUT interface (pistol slide or mount must have an A-CUT cut), finished in Black. Like every Aimpoint sight, it is operationally parallax-free: the dot stays parallel to the bore no matter where your eye sits behind the window, so if the dot is on the target, so is your zero. In the box you get: CR2032 battery, Aimpoint tool. Add the Aimpoint COA 3.5 MOA sight to your cart at BattleHawk Armory and set your firearm up with an optic that professionals have trusted for decades. 3.5 MOA Aiming Point and Daylight-Bright Clarity The 3.5 MOA dot is the heart of the COA. A dot this size covers little of the target at distance for precise shots while staying easy to pick up quickly at close range. The sight offers 4 night vision compatible settings and 8 daylight settings, so you can turn the dot down for use behind night vision devices or up for bright sunlight. Night vision compatibility makes it a natural fit for low-light and professional use. Battery Life and Power The COA runs on a single CR2032 battery and is rated for 50,000 hours (over 5 years) of constant operation. In practice, that means many shooters can leave the sight switched on and replace the battery on a set schedule rather than worrying about whether the optic will be ready when it is needed. Long run time is one of the main reasons Aimpoint sights are chosen for duty guns, home defense firearms and hunting rifles that need to be ready without fuss. Built Rugged for Hard Use The housing is 7075-t6 high strength aluminum, enclosed emitter, and the sight is submersible to 82 feet (25 meters). Aimpoint designs its sights to stand up to recoil, impacts, weather and temperature swings, which is why so many military, law enforcement and civilian shooters rely on them.
