It is an indispensable tool in a Call of Duty. It makes target acquiring and tracking almost effortless and dead-accurate, and we pray to have one mounted on our weapon if we ever find ourselves in a gun fight. Yes, it is the red dot scope, and it is an excellent addition to most firearms, not just rifles.
There is an extensive range of riflescopes which might be more effective than red dot scope for acquiring moving or long-range targets. Nevertheless, red dot sights are ideal for swift target acquisition. Nothing can compete with having a striking reference point that can be used to pinpoint targets easily, allowing you minimize reaction times and achieve nearly instantaneous shots.
Red dot scopes functions by using light from a red light-emitting diode (LED) that is then narrowed by a spherical collimating mirror in order to create the characteristic red dot as a reticule or aim point. This system ensures that the red dot is aligned with the weapon that it is attached to regardless of eye position, allowing it to be used as a reference point for aiming.
These scopes have quite a few other desirable features, aside from rapid target acquisition. They are light and small, therefore very portable. There is no magnification involved which gives the user a wide field of vision, minimal parallax problems, and maximal eye relief. Since the reticule is emitted by the device itself, it is independent of external factors, and can function in nearly all lighting or weather conditions. These sights are also not affected by recoil, and are energy efficient, capable of lasting for up to thousands of hours. They are firmly mounted using Weaver style bases and can be placed from 5 to 30 cm away from the eye. The minute of angle (MOA) of the reticule can be adjusted easily and comes in dot sizes 1, 4, 6, 8 and 10. The larger the dot size, the easier it is for most people to find their target. A few models have sights which are enclosed in multi-coated rubber casings to ensure they are fog and shock resistant.
Therefore, with their adaptability to varying environments, red dot sights come in handy whenever weapons are in the picture. Whether you are a hunter hunting for hiding prey, a soldier undergoing a mission in a dimly-lit location, a police trying to take down an armed suspect with hostages, or a Prepper defending yourself from Zombies, the red dot sight can ease your burden greatly.
