The Holosun HS403B is a 20mm micro red dot sight for rifles and carbines that helps focus the shooter's eye on the target for rapid acquisition. This optic features a red-illuminated 2 MOA reticle with 12 brightness settings for various low-light conditions. Powered by a single CR2032 battery, the HS403B has a 50,000-hour battery life and uses the Shake Awake feature to help preserve the battery by powering off the optic when not in use. When the battery fails, it's easy to swap it out for a fresh one, thanks to the convenient battery tray on the optic's side. Included with the optic are a lower 1/3 cowitness mount, low profile mount, T10 L key, rubber cover, battery, and lens cloth, so it's ready to be installed right out of the box. This model features 6061-T6 aluminum housing and has an FDE finish.Features:
