The type of mount for mounting sights provided in the design of the rifle. Most often in such cases we are talking about an optical or collimator sight; and the most popular mounting options are
Weaver/Picatinny rail and
dovetail. Here are their features:
— "Dovetail". This type of mount has a cross-sectional view of an inverted trapezoid (expanding upwards); the clamp on the sight covers this trapezoid from two sides, and the transverse cutouts, unlike the Weaver / Picatinny rails, are not provided for in the design — fixing in place is carried out in other ways. Dovetail mounts were originally used in civilian hunting rifles, as well as in Soviet-style military weapons. Nowadays, due to their simplicity, low cost and versatility, they are extremely common in air rifles. In addition, we note that you can even install a Weaver / Picatinny rail on a dovetail (such rails are available separately) and use a sight with the appropriate type of mount.
— Weaver / Picatinny rail. Fastening in the form of a bar with a T-shaped profile and characteristic transverse slots — they serve to rigidly fix the installed accessories in one place. Technically, Weaver and Picatinny rails are different types of mounts, they differ in the size of the slots; these differences are such that the sights and other “body kit” for the Weaver rails easily get on the Picatinny rail, but the opposite option is far fro
...m always possible. However, in the civilian market, most weapon accessories for such slats are made specifically for the weaver, so this nuance, most often, is not fundamental, and both types of slats are combined into one category.
In general, for a number of reasons, such straps are much less common in air rifles than the dovetail. At the same time, classic pneumatics are most often equipped with Weaver mounts, but in airsoft copies of real weapons, Picatinny rails (or compatible NATO STANAG 4694 rails, also known as RIS 22 mm) can also be used.
— Is absent. The absence of any standard mounts for the sight in the design of the rifle. Most often, this designation means that the rifle is equipped with a classic front sight with a whole and does not require the installation of additional sights. However, there is also a more specific option — pneumatics, in which original mounts are used to install optics or a collimator, which are not related to the standards described above. Such rifles can be supplied with or without scopes; there are even models with non-removable optics, although extremely rare.The ability to adjust the location of the emphasis under the cheek, located on the butt. Usually, we are talking about at least height adjustment, and in advanced models it may also be possible to move the stop back and forth. Anyway, this feature allows you to adjust the position of the cheek to the physique and personal preferences of a particular shooter, thus providing the most comfortable tab — and this convenience, in turn, has a positive effect on accuracy. At the same time, the ability to
adjust the cheekpiece significantly increases the price of the rifle, and therefore it is found mainly in top-class models.
