Riflescopes basics

The riflescopes are one of the most important accessories in the panorama arms, offering the shooter the opportunity to get a fairly accurate shot at long range. To properly use these scopes essential to understand fully all of its components. Only this way the shooter can extract optimum performance over the entire viewfinder weapon. Here are some of the key concepts of the many lenses used with weapons.

730132POpening:
The opening degree indicates the diameter of the front lens of a Riflescopes. The aperture is expressed in millimeters and always next to the increases. For example, an 8x viewfinder 56 presents an opening of 56mm front lens. This is a really important thing in telescopes as against your gains are larger, the larger opening. This is because the most powerful riflescopes require more light to give a good image to the shooter.

Parallax adjustment:
The term refers to parallax time when the goal is not clearly focused within the lattice. This occurs when a sudden movement by the shooter or when changing the distance of the shot. Viewers increases of up to 11 are factory set with no parallax for distances less than about 110 meters in the central firearms. Those who exceed these increases have a ring, usually located in the front lens, which allows the shooter to adjust the parallax and prevent blurred grids.

Increases:
They represent the power that has a particular viewer to visually bring the target to the shooter. Are expressed by a figure accompanied by an “x” for example 6x. This means that the shooter to aim a 6x viewer is seeing the target 6 times closer than when they look to the naked eye. At a magnification riflescopes are also called power.

Field of view:
Represents the width and height of an image through Riflescopes spotted an overall distance of about 100 meters. When the field of view increases, the shooter finds it easier to locate their targets. The problem can come up when you use too big for shots at close range, as the field of view is significantly reduced and the shooter does not control all of what is happening around you.

Eye point:
Indicates how far accurate ocular (rear lens) the shooter can see the full picture in the viewfinder. Viewers powerful weapons equipped must present a greater eye relief, so as to prevent injury to the shooter with the display caused by the sharp fall after a shot. It is also recommended that the viewers for pistols have a great distance to the eye, so you can see the whole picture at arm’s length.

Resistance:
All viewers that boast quality must submit a nitrogen blanket that insulate and protect them from rain, humidity, and even sudden temperature changes. The nitrogen filling prevents the formation of humidity inside the visor and thus prevents fogging under all circumstances. Similarly, all turrets and adjustment rings must be completely sealed to prevent ingress of dust or particles which might damage its operation.

Optical treated:
Some viewers feature a special coating on their surfaces that avoids the appearance of unwanted glare and reflections. These optical fluorato treated with magnesium or ruby ​​layers also improve the viewfinder image in low light conditions.

Exit pupil:
Indicates the diameter of the column of light that leaves the viewer into the eye of the shooter. Used to know and assess the degree of brightness of the image you see in the optical. The higher the value of the exit pupil, the easier it is for the shooter to keep his eye aligned with the image. Similarly, the larger the index, the RIFLESCOPESr offer better performance in low light conditions.

Reticle:
It is the key element of riflescopes, as it serves to the shooter establishes his shot and tune your aim. It is represented by a “cross” which works as a reference central point to handle focus your shot. There is a wide and varied range of grids and we can even find them electronically lit. In general, grids that have a thicker cross used in shots at close range and moving targets, while finer grids are preferred by long distance shooters.

Lens caps:
Its main function is to protect the objectives of the dust and possible scratches or accidental scratches. However, there are some covers with colored plastic, in an emergency, allow the shooter to shoot without removing them. There is also a special type of cover known as “Flash Kill”, which has a shape similar to a honeycomb and prevents any reflections caused by the lens. This cover is widely used by snipers, allowing them to hide at all times the enemy position. Finally, there are the so-called tapas “flips up” with a simple tap rising operating alone and quickly leave the riflescopes.

Adjustment turrets:
Two sprockets that correct and adjust the display grid. The top turret controls the elevation turret while the charge to correct lateral lateral deviations. The turrets precise viewers have a scale that allows the shooter to make adjustments depending on the weather conditions (wind) or to possible movements of the target. The manuals for these viewers incorporate a section showing the degree of correction experienced by the viewer for each “click” adjustment turrets.

* The best quality and best brand of riflescopes.
