Comparison Hatsan MOD 125 Combo vs Hatsan MOD 125TH

The type of sight the rifle is originally equipped with. Note that many models allow the installation of other sights — in addition to standard sights or to replace them. And the optics or collimator can initially be combined with a mechanical sight (front sight + rear sight), which in such cases plays the role of a spare. However, these features are not available in every rifle, so when choosing, it is best to focus on the type of complete sight.

Nowadays, in addition to the traditional sighting bar with a front sight, in air rifles you can find diopter, optical and collimator sights, and in some models regular sights are completely absent. Here are the features of each of these options:

— Aiming bar and front sight. Devices in the form of a front sight and a rear sight, which has the form of a horizontal bar with a slot; when aiming, you need to combine these devices so that the front sight is visible exactly in the middle of the slot and flush with its edges. Such sights are extremely popular in modern pneumatics: they are as simple as possible, inexpensive, compact and reliable, besides they do not depend on batteries and are quite resistant to shock and shock. In addition, the front sight with a bar is not as restrictive as an optic or a collimator, and is better suited for shooting at moving targets....The main disadvantage of this option can be called the fact that effective aiming requires a certain skill — after all, you need to control not only the aiming itself at the target, but also the relative position of the front sight and the slot. On the other hand, this moment can turn out to be a virtue — in particular, when learning to shoot: having learned how to shoot effectively with such devices, the shooter will feel quite confident with other types of sights. It is also worth noting that the front sight does not give any magnification — this makes it difficult to shoot at small and/or distant targets; however, again, this feature is not always a clear disadvantage.

— Diopter sight. A kind of mechanical sighting devices (that is, front and rear sights), using the diopter principle of operation. The rear sight in such devices is a plate with a small hole through which the shooter looks at the front sight. Such a rear sight is easier to use than a traditional slotted rail, especially for beginners: even without special skills, the shooter subconsciously chooses the position of the eye in which the front sight will be in the centre of the hole (as it should be when aiming). In addition, the small aperture gives a slight zoom effect and enhances target definition, which is especially important at longer distances. On the other hand, diopters noticeably limit the view, are poorly suited for low-light conditions and are easily clogged with various contaminants. Therefore, this type of sight is used extremely rarely in pneumatics — mainly in powerful long-range rifles, mainly for sports purposes.

— Optical sight. Traditional optical sights in the form of a "spyglass" with a reticle applied in the field of view of the shooter. Initially created for high-precision long-range shooting, mainly at fixed targets; in the same role are used for pneumatics. However not every air rifle with optics is a powerful long-range weapon — there are also relatively “weak” models. But even such pneumatics can be a good training tool for high-precision shooting: a small distance in this case can be compensated for by a small target size. On the other hand, optics significantly affect the price of the rifle and require careful handling. Of its features, it is also worth noting that such sights necessarily have a certain magnification; due to this, they allow you to better consider small targets at the same time limit the field of view. It should also be borne in mind that optics are not well suited for offhand shooting and require careful insertion: the eye must be exactly on the optical axis of the sight, otherwise the aiming point may not coincide with the point of impact.

— Collimator sight. The working part of a collimator sight is a glass window onto which a luminous aiming mark is projected using a special optical system — a dot, crosshairs, a circle with a dot, etc. Sights of this type usually do not have magnification and are intended for shooting at short distances, including on moving targets and offhand. So in application, the collimator is similar to the front sight with the whole; and its key advantage lies in ease of use: no need to combine the front sight and the slot, just find the aiming mark in the window and aim it at the target. At the same time, unlike optics, it is not necessary to keep the eye strictly opposite the centre of the sight: the parallax effect (see "Adjusting parallax") in collimators is very weak, if not absent at all. The main disadvantage of this type of sights is that they require batteries to operate; in addition, collimators are noticeably more expensive than traditional mechanical sights, and also require more careful handling (although they are still less delicate than optics).
It's worth noting that these attachments are especially popular with airsoft guns like most AEGs (see "Type"): collimators are great for fast-paced fights.

— Is absent. The absence of any sighting devices in the original delivery set — there are only mounts for installing such devices. See below for more details on the different types of fasteners; here we note that such equipment does not allow the use of a rifle “out of the box”, however, it makes it possible to choose a sight for it at your discretion, without relying on the choice of the manufacturer. This is especially true if you plan to use optics — nowadays a wide variety of such sights are produced, for different tasks and usage scenarios. Actually, most air rifles without a scope are designed just for the installation of optics, although the possibility of using collimators is often also allowed; and in airsoft pneumatics, removable front sights with rear sights are also used.
It is worth noting that spring-piston rifles and models with a gas piston have a specific double recoil, which not every sight is able to transfer — even if it can be used with powerful firearms. So when looking for optics or a collimator for such pneumatics, you should be especially careful — for it you need to choose sights that were originally designed for such rifles.

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 f...ar from 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.

The degree of magnification provided by the rifle's complete optical sight; for models with variable magnification, the entire adjustment range is indicated, for example 3 – 9x.

For sights of this type in general, see "Aiming Device". And several points depend on the degree of increase at once. On the one hand, a higher magnification allows you to better see small and/or distant targets and facilitates high-precision shooting; on the other hand, it limits the angle of view and significantly affects the cost of the sight, and sometimes also its dimensions and weight. And since air rifles are mostly not designed for long distances, the magnification of complete optics in them usually does not exceed 9x, and one of the most popular options is 4x. However, there are exceptions: in powerful high-end pneumatics, you can find sights with a maximum magnification of 24x and even higher.

Actually, the manufacturer most often selects the magnification of optics for the ballistic characteristics of the rifle. So, when choosing this parameter, it often turns out to be secondary, and it makes sense to focus primarily on the muzzle velocity of the bullet and the firing range for which the weapon is designed — usually, the capabilities of complete optics are quite enough for this. It is also worth mentioning the variable magnification sights mentioned at the beginning, which are quite common nowadays — they are somewhat more complicated and more expensive than fix...ed optics, but they allow you to adjust the magnification to the specifics of the situation.

The diameter of the front lens (objective) in the optical sight, which is equipped with a rifle.

For sights of this type in general, see "Aiming Device". And the diameter of the lens depends primarily on the amount of light entering the scope. Thus, other things being equal, a larger front lens produces a clearer and brighter image; this is especially noticeable in low light. On the other hand, a larger lens is noticeably more expensive, and it also affects the weight and dimensions of the sight; and in bright daylight, the difference from the “smaller” optics may not be fundamental. In addition, recall that the actual image quality is determined by a number of other factors; as a result, high-end optics with a relatively small front lens may well be more effective than a large low-cost model.

In view of the foregoing, it is worth paying attention to the diameter of the lens in cases where the sight is planned to be used in low light conditions — in a dense forest, at dusk, etc. In this case, it is worth considering not only this indicator, but also other features of the optics (and it is best to focus on practical reviews). If the rifle is bought for recreational use in the daytime in good light, the size of the lens will be a purely reference parameter: in such conditions, almost any optical sight works normally.

— Tree. A classic material used in firearms and then pneumatic weapons since ancient times (in fact, since its inception). Wooden stocks are strong enough on their own, and in modern rifles they are also amenable to special treatment to protect against dampness, temperature changes, etc .; while the rifles have a nice appearance in a classic style. At the same time, the wood is prone to abrasion, scratches easily appear on it, and there is a possibility of cracks. When used in simple conditions, such as periodic "shooting" in the country, this does not matter, however, for example, a wooden stock is not suitable for hunting — at least because it will quickly lose its "presentation". At the same time, this material is also somewhat more expensive and more difficult to process than plastic that is more resistant to “troubles”. Therefore, today the tree is used mainly in pneumatics of the middle and upper price range and is designed for those who are primarily interested in the aesthetics of weapons.

— Plastic. One of the most popular materials for the manufacture of modern pneumatics. Such stocks are easy to manufacture and inexpensive, while the plastic can be given a rather complex shape without any problems, which, in particular, facilitates the installation of various adjustment systems (see “Cheek Adjustment”, “Butt / Stock Adjustment”). However, its main advantage is practicality: this m...aterial is resistant to impacts, cracks and scratches, comparable in strength to wood (or even superior) and has a small weight. As a result, plastic has become widespread in almost all price ranges.

— Aluminium. A fairly advanced material that combines low weight and high strength. On the other hand, aluminium stocks for classic pneumatics are generally expensive, and therefore are used mainly in high-end professional models (although there are exceptions). But in airsoft rifles that copy real weapons, the situation is somewhat different: there aluminium can be used as a simpler and more affordable alternative to steel (from which gunshot prototypes are made).
