Abstract
A red dot optical sight apparatus for a firearm having an optical element and a light emitting diode disposed at the focal point of the optical element, in which at least the optical element is pivotal between a lowered, inoperative position and a raised, operative position. The apparatus further includes spring biasing to assure that the optical element is in a precisely defined position when pivoted to the raised, operative position.
