Optical sight device, which is fixed on the arms for better aiming at the target. Distinguish between day and night optical sight, the first of which is intended for use in the daytime.
The design of the optical sight consists of the following elements:
1. Lens. Consists of two or more lenses. The lens shooter, in fact, sees a magnified image of an object an upcoming shot. The larger the lens diameter, the better the image.
2. With the help of the inversion system inside the device, the image being observed from upside-down is straight. Ie, thanks to this design element, we see the object of shooting is not "upside down", and, as expected, "head-up".
3. The reticle represents deposited on a glass plate drawing, is used directly for convenience of an aiming. Thanks to this grid, the shooter sees the lens the image is lined. The location of the lines indicate where you have shot (crosshairs), and in some cases allows you to calculate the distance separating the shooter and the target.
4. It is impossible to lose sight of this element as an eyepiece. It looks into the eyepiece of the aiming eye. Characteristics of ocular destruction. It's the distance from which you can see in the eyepiece without the danger of damaging the eye as a result of recoil of the shot. Typically, the value of removal - a few tens of mm.
5. If the reticle makes aiming easy, for the sheer enjoyment of sight "meets" the mechanism of input of horizontal and vertical amendments, to move the reticle in the image plane observed through the eyepiece. Using this mechanism, align the reticle with the desired object, and fire! In some cases the mechanism allows to take into account parameters such as the deviation of bullets flying in a strong crosswind, moving targets, etc.
6. At dusk or amid dense vegetation thin reticle (see P3) becomes invisible to the shooter's eye. To overcome this difficulty is provided a node illumination reticle, this device, whose name speaks for itself. Highlighted maybe the markings or the Central part, and in some cases only the point where you have shot. The supply of light is carried out, in most cases, with the help of LEDs. Scopes, in which the brightness can be adjusted, it seems preferable.
7. And finally, a uniform design of all these elements brings together the body of the sight.
After this brief review of the components of the optical sight, it would be appropriate to look at the quality and features of this device as a single integrated system.
The sights of different magnification (zoom). There are two type of sights: with constant and with variable magnification. The first of these give the lens the image once and for all fixed scale. The second by adjusting the size of the image: the shooter can "zoom in" or, conversely, "zoom out" of the observed objects. If You know, for what purpose and in what conditions will you catch in the lens of Your sight, You'd better choose a rifle scope the first type, the most suitable for Your needs increase. Devices of the second type are inferior in the first image quality, but more versatile. If aim have from unprepared positions, "to take on the fly" and the moving and the static objects You no longer fit the sight with variable magnification.
Choosing a particular model, make sure that You chosen the sight you overcome the parallax effect. Properly sight the target image in the lens does not coincide with its image that the shooter sees in the eyepiece. This is the parallax. No need to explain what a parallax is, to put it mildly, is not conducive to hitting the target. The top-quality rifle scopes to eliminate the parallax, a mechanism of the focusing lens. In most devices, the parallax is reduced to zero by moving the lens. The lens, in this case, the scale is applied; the lens moves on the number of divisions determined by the distance that you are shooting.
And finally, scopes can be classified by method of attachment to the weapon. Specialized riflescopes are designed for installation on a weapon of a specific type. In the design of these scopes provided by fasteners, therefore, to acquire any additional fixtures, there is no need. While universal sight - which can be installed on the different weapons will need a bracket.
Depending on the type of weapon, the bracket - which, in turn, fixed sight set one of two ways:
1) Side mount. The bracket is mounted on the bar type "swallow's tail", located on the side, on the receiver of the gun. Method solely "Soviet" and Russian. In this way, the brackets are attached to hunting weapons made on the basis of the Kalashnikov assault rifle, carbine "boar", etc.
2) Upper anchorage. Vertical mounting on the bar type "swallow's tail", the Russian weapons and the same items imported models.
General recommendation on the choice of scope is that the scope must match exactly the weapons that will be installed. For small-caliber or even semi-automatic weapons should not put the sight of the "higher" category, as the quality and characteristics of the weapons that still doesn't change that. But cheap scope mounted on a precision weapon, easily negates its high ballistic characteristics.
In General, as in any business, You must first clearly answer the question: what is and what you need. If You do, You will find the scope that best suits Your goals and hitting Your intended purposes :-)
Good hunting! |
