The invention may take form in various components and arrangements of components, and in various steps and arrangements of steps. The drawings are only for purposes of illustrating preferred embodiments and are not to be construed as limiting the invention.
Firearms and other weapon systems commonly utilize laser emitters for a number of purposes. For example, aiming lasers having one or more laser emitters bore-sighted to the barrel of a firearm or other weapon are used as weapon sights for aiming the weapon. Similarly, laser illuminators emit a beam to illuminate a target area and are often paired with aiming lasers. Laser emitters are also used to mark or designate enemy targets to pinpoint the location of enemy targets and reduce the chance that friendly forces are mistaken as an enemy target. Commonly, laser accessory devices will employ a lens cap or cover to cover the laser emitters when the unit is not in use, e.g., to keep the laser lenses clean and/or dry as well as preventing accidental laser emissions. The present development contemplates a new and improved cover system for laser accessory devices.
