What Is Red Dot Sight?

A red dot sight is an optical device attachable to a wide variety of guns. It basically gives you a greater advantage over your target. It is widely used by hunters, law enforcement officials, as well as military personnel. It allows for the greater effectiveness of shots, in terms of accuracy and precision. The best budget red dot sight for AR15 will enable you to be on your mark time and time again.

This device is mounted on a gun rail and works similarly to a telescopic scope. The difference is, the scopes are used to magnify the image. A red dot sight, is used to pinpoint the part of the image which the shooter wishes to target. This is done by illuminating the reticle onto the image of the target being viewed through the window. The reticle is usually produced by a laser or a LED light which helps in acquiring perfection while aiming.

Besides this, certain manufacturers use green lasers or LED lights to illuminate the target. In other cases, the reticle design may be different. Thus it is clear that red dot sight comes in a wide variety of shapes, sizes, designs, and forms.

There are certain auxiliary benefits that come with the red dot sights. Shooters will have the opportunity to reduce and minimize eye fatigue while achieving higher consistency levels. The device also helps in better vision in low lighting conditions, and helps achieve greater stealth in special operations. The functioning of these slick devices can also be augmented – by pairing it with magnifiers and night vision equipment.

Factors to Considered while Choosing the Best Budget Red Dot Sight for AR15

Reticle Size and Pattern

The aimer that is projected onto the objective lens is called the reticle, and the type of reticle you need is one of the most crucial factors that should determine your purchase. It is an illuminated dot or any other intricate design that essentially pinpoints the target.

Reticles need not only be a dot but can also be displayed a chevron pattern or even a triangle. The purpose of the gun should be kept in mind while utilizing the right reticle. For instance, a smaller dot is best suited in long-distance shooting. Reticles may also take more refined and versatile forms. Some reticles have an outer ring with a smaller dot in the center, that helps in long distance accuracy. The outer rings are used to provide greater direction and consistency.

Some red dot sights may also take the form of cross hairs or grid lines, that are used to determine the distance. High-end reticles are extremely versatile and often include multiple reticle styles that can be changed depending upon the requirements of the situation and surroundings.

Reticles use the minute angle of measurements to determine sizes – much like scopes. Smaller minutes of angles represent smaller dots while circles and cross hairs may also be specified, allowing the shooter to get a more comprehensive idea of using the sight. Highly skilled shooters often use the design and minute of angle measurements in the reticle to determine their distance from the target.

Types of Reticle Projection

The uniqueness of the red dot sight is derived from the projection of the reticle. Red dot sights are projected either as reflex or holographic sights, and are used to classify the sights themselves.

Hunters use the reflex sights a lot more than other shooters. An LED is placed behind the lens, that shines onto the objective lens. This then acts much like a mirror, and ultimately reflects the light into the eyes of the shooter. The interesting part is, that the mirroring image isn’t noticeable – as the lens merely reflects the wavelength of the LED. This is while allowing all other wavelengths to pass through. This LED produces the reticle, while giving the impression that it gets projected onto the target.

Tube and Open Design

The constituent components of red dot sights could vary in different ways – depending upon the aspects of technology and classification. In matters of design, the device components can be either closed off in a tube or open.

Tube sights have a lot of resemblance in their appearance to standard scopes. All of the necessary components are housed by their tube designs, and they can act as a great option for shooters looking for a more rugged alternative.

All of the components of the device are protected in the metal tube casing. Tube sights also provide greater versatility, as they can be used with filters for attaining greater control in changing conditions. A tube sight will also give you much better visibility. This is applicable even in sunny conditions, as the tube essentially helps to block out the sun and allowing a much clearer image for the shooter.

Open sights, on the other hand, are known to be less bulky and have a significantly smaller footprint. These are also called “mini red dots”. These sights don’t have any unnecessary components, and generally sport a bare design that is responsible for housing only the objective window and illumination source. The downside is that these sights are not considered to be a good choice for working with filters.

Battery and Power

Battery power is used to illuminate the reticles in most cases for red dot sights. The lifespan of the battery is important and should be considered as crucial, while choosing the best budget red dot sight for an AR15. Holographic lights usually have a smaller battery span, as compared to reflex LED lights. Due to the use of laser energy, holographic lights require more energy and typically run out of juice much quicker. LED lights, on the other hand, are famous for low energy consumption, and their batteries can sometimes last up to 1000 hours before they need to be replaced.

Nowadays, with the rapid transformation and advancement of technology, sights are equipped with alternative forms of power. These new-gen sights use fiber optics and tritium capsules for power. Sights such as these, do not have any electronic components, but they sometimes can suffer when it comes to illumination. It has been widely reported that many such sights have been rendered effectively useless, as they have to washed out in brighter locations. Nowadays cutting-edge technology allows us to enjoy the experience of sights for hours on end, without having to worry about replacing or replenishing the power source.
