For Sport or Duty, the Holosun 403 Will Get You on Target

The Holosun HE403B features a 2 MOA dot, a 50K hour battery life from a 2032 battery, and shake awake technology for unrelenting reliability on your duty, sporting, or home defense firearm. With 12 brightness settings, 10 daylight and 2 night-vision, the H403B-GR green dot can be matched to almost any lighting situation or environment with the press of a button.
