Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    Embodiments of the invention relate to a dot sight device that is designed and built for firearms, especially heavy and medium size machine guns, for the purpose of all armed forces, hunters, and police departments. A dot sight device offers a very large field of view design that provides rapid target acquisition for both stationary and moving targets. In addition, a dot sighting device also provides pin-point accuracy, which ensures every round is on target to ultimately suppress enemies faster, reduce collateral damage, and conserve ammunition. 
         [0003]    2. Discussion of the Related Art 
         [0004]    Iron sights are commonly used by shooters for aiming firearms such as rifles, or medium and heavy machine guns. Each iron sight requires the shooter to align a rear and front sights of a rifle along with the target, which requires trainings and shooting skills. 
         [0005]    Dot sights were developed for the purpose of offering rapid target acquisition of both stationary and moving targets with limited training. A dot sight can easily convert non-experienced shooter into a skilled marksman. A dot sight is also commonly known as a non-magnifying reflector (or reflex) sight that is mounted on firearms to provide the shooter an aiming indication in the form of a red dot. Dot sights are designed and developed to offer sportsmen, hunters, policemen and soldiers the ability to acquire and engage target or targets quickly and effectively. Dot sights are user friendly devices in the sense that it only requires the shooter to position the dot on the target and upon pulling the trigger, a projectile will impact the point of aim. 
         [0006]    A standard dot sight design uses a red light-emitting diode (LED) at the focus of collimating optics, which generates a red dot or an illuminated reticle that stays in alignment with the weapon. The dot sight then may be attached to the weapon regardless of an eye position (i.e., parallax free). 
         [0007]    A dot sight can also use an infrared light source at the focus of the collimating optics to generate a light that is invisible to the human eye. By using an IR coating technology, an illuminated reticle will then be visible at the lens that stays in alignment with the weapon. The dot sight then may be attached to the weapon regardless of eye position (i.e., parallax free). 
         [0008]    A parallax free dot sight refers to a visible dot that remains parallel to a bore of the firearm, so no matter what position the shooter&#39;s eye is in, it will remain relative to the sight allowing the shooter to engage target or targets in stationary or moving platforms (i.e.—helicopters and boats). 
         [0009]    A very large field of view design enables the shooter to keep both eyes open during operation to enable an unlimited field of view at any distance. The eye relief is also unlimited, which means that the shooter&#39;s eye position behind the sight does not affect how well the shooter sees the target 
         [0010]    Shooting with both eyes open offers the shooter enhanced situational awareness to allow the possibility to deal with multiple targets. A dot sight helps a shooter become an effective marksman offering ability to aim accurately and quickly under any extreme or stressful conditions
