Comparison Hatsan SpeedFire vs ZBROIA Kozak

The type describes the basic principle of operation of the rifle. Nowadays, you can find pneumatics with a spring-piston principle of operation (with a conventional or gas spring), with pre-pumping (PCP), with pumping before each shot ( multi -compression rifles), powered by carbon dioxide cartridges and with an electric drive. Here is a more detailed description of each of these types:

— Spring-piston. As the name suggests, the basis of the mechanism in such rifles is a spring-loaded piston moving in a cylinder. The weapon is cocked manually (usually by a lever or a broken barrel), while the piston is retracted and fixed, the cylinder is filled with air, and when the trigger is pressed, the piston is released and moves forward under the action of a spring, pushing air from the cylinder into the barrel. Rifles of this type have simplicity and reliability of design, low cost, unpretentious maintenance, as well as ease of repair and tuning; they are considered an perfect option for beginner shooters, as well as for lovers of entertaining "shooting" at short distances, there are also models for airsoft among them. It is also worth mentioning the excellent repeatability of shots (with each cocking, a strictly defined portion of air enters the cylinder) and insensitivi...ty to heat and cold. On the other hand, such rifles require cocking (and most often reloading) before each shot, which can be quite tedious; and the operation of the piston mechanism creates a specific recoil, which adversely affects accuracy and makes it difficult to select optical sights (requires special optics, originally designed for this application). In addition, pneumatics of this type cannot be kept charged for a long time — with prolonged compression, the mainspring loses its properties.

— With gas spring. According to the general principle of operation, rifles of this type are similar to the spring-piston ones described above. The difference lies in the fact that instead of a conventional metal spring, they use a sealed reservoir with a special gas, which plays the role of a spring — shrinking when cocked and expanding when fired. This design has a number of advantages over conventional spring-piston. Firstly, the whole mechanism is much smoother and quieter, and the recoil is softer, which improves accuracy and simplifies the selection of optics. Secondly, the gas spring does not change its properties as it wears out, and such weapons can be stored even in the cocked state. Third, repairs and maintenance for gas springs are less frequent and less expensive (in terms of the number of shots between workshop visits). The disadvantages of rifles of this type, in addition to the need to cock the spring before each shot, include a slightly higher cost than that of classic spring-piston rifles, as well as sensitivity to cold: when the temperature drops, the gas pressure in the spring decreases, which worsens efficiency.

— PCP (pre-pumping). The energy source in rifles of this type is a built-in reservoir containing air (or other gas) under very high pressure — about 200 or even 300 atmospheres. Such a reserve is enough for at least several dozen shots, and a compressor, a scuba cylinder or a special high-pressure pump can be used to fill the tank (sometimes such pumps are even supplied as a kit). In general, PCPs are considered the most advanced type of pneumatics, and these are the rifles used by professional hunters and sportsmen. This is primarily due to the fact that such a design allows you to achieve a very high speed of the bullet, and the recoil is almost imperceptible — all this allows you to accurately shoot even at long distances. On a fresh gas station, the rifle gives excellent repeatability of shots; however, as the gas is consumed, the initial velocity of the bullet decreases, however, in advanced models, a gearbox may be provided to compensate for this phenomenon (for more details, see “Air supply by the gearbox”). PCP pneumatics can be easily multi-shot and provide very simple and convenient ways to feed the next bullet into the barrel. The main disadvantage of such rifles is the high price.

— Multi-compression. Another variety of rifles with a built-in reservoir; however, unlike the PCPs described above, the reservoir must be inflated before each shot. To do this, the design provides for a built-in pump controlled by a lever or other similar device; to pump enough air, usually, you need to make several movements. In such rifles, there is practically no recoil, while they are noticeably simpler and cheaper than PCP pneumatics, but they are inferior to it in terms of power. In addition, pumping up the tank before each shot is quite a tedious task; and the volume of air supplied to the tank at each filling (and, accordingly, the working pressure in the tank) will depend on the number and amplitude of movements made by the pump lever. On the one hand, this allows you to adjust the power directly “on the go”: for example, for a short range where maximum bullet speed is not required, you can not fully pump up the rifle in order to save energy. On the other hand, the actual volume of air and the pressure in the tank will be somewhat different with each recharge, even with the same number of lever movements. This negatively affects the repeatability of shots. Due to this combination of features, multi-compression models are not very popular nowadays, and their purpose is mainly recreational shooting.

— Gas balloon. A type of pneumatics powered by interchangeable cartridges of gas, usually liquefied carbon dioxide. As in PCP, such a tank allows you to make a lot of shots — even a traditional 12-gram can is usually enough for several dozen; and some models use 88g carbon dioxide containers. At the same time, the rifles themselves are cheaper than PCP, but they have less power. It is also worth noting the rather specific characteristics of carbon dioxide as an energy source. On the one hand, it maintains working pressure for quite a long time — it does not decrease as long as carbon dioxide remains in liquid form in the cylinder. On the other hand, the actual gas pressure depends on the ambient temperature, and the initial velocity of a bullet for such pneumatics can change markedly even with daily temperature fluctuations. And of the unambiguous shortcomings of such rifles, it is worth noting that for them you have to buy not only bullets, but also gas.

— AEG (electrically driven). Pneumatics that uses an electric motor drive as a power source. According to the design of the working mechanism, it is similar to the spring-piston mechanism — the basis of this mechanism is a cylinder and a spring-loaded piston. However, the piston in this case is not retracted manually, but with the help of the mentioned electric motor. For the shooter, this means, first of all, that the rifle does not need to be cocked due to muscular strength — for a shot, it is enough to press the trigger, the rest will be done by the electric motor. In addition, in such pneumatics, automatic firing mode can be provided without problems (see below). Note that for a number of reasons this principle of operation is practically not found in traditional pneumatics, but it is very popular in airsoft models; such rifles (“drives”) often copy real military weapons.

Rifles made according to the Bull-Pup layout are distinguished by a non-standard arrangement of the trigger and magazine: the magazine (and, most often, the cocking and chambering mechanism) is not in front of the trigger, but behind it, usually in the butt, and the trigger is taken out due to this forward, almost to the middle of the weapon.

In the case of pneumatics, the key advantage of this arrangement is a comfortable balance. The main handle in bullpups is located approximately in the region of the centre of gravity, due to which the rifle becomes more “manoeuvrable”, it is easier to transfer fire vertically and horizontally, and the barrel does not tend to tilt forward so much, and it is easier to support it with a second hand. In addition, due to this design, it is possible to achieve a large barrel length without a significant increase in the dimensions of the entire rifle, which in some cases is an advantage (for more details, see "Barrel length"). On the other hand, moving the handle forward noticeably complicates the weapon, increases its cost, and can make it difficult to reload. In addition, not all bull dads are convenient for left-handers — on the right side there may be various elements (a protruding magazine, a shutter handle) that complicate the tab on the left shoulder, and special "left-handed" versions of such models are extremely rare.

It should also be borne in mind that due to the layout features, such rifles are designed mainl...y for the use of optical / collimator sights and are almost never equipped with a classic full sight. However for the bar provided in most bullpups, you can also install removable flies with rear sights, but this is hardly justified: the aiming line is too short, which makes it difficult to achieve accurate shooting.

Note that in AEG drives (see "Type") the bull-pup format is used for other reasons — in models that copy the appearance of real weapons in this format.

The muzzle velocity provided by the rifle - that is, the speed of the bullet as it exits the barrel.

All other things being equal, a higher bullet speed provides greater range and accuracy, and also simplifies aiming at long distances: the bullet flies along a smoother trajectory and requires fewer adjustments in height, and the influence of side winds decreases with increasing speed. On the other hand, this indicator directly affects the price of the rifle; and in some countries, legal restrictions on the ownership of pneumatic weapons are also related to the muzzle velocity of the bullet.

As for specific values, in the weakest modern rifles the initial speed does not exceed 150 m/s, and in the most powerful it can be 300 - 350 m/s or even more(remember, the speed of sound is 330 m/s). In general, for recreational shooting at short distances, this parameter is not particularly important, and detailed recommendations for choosing pneumatics for more specific situations can be found in special sources. Let us only note that in AEG electric drives (see “Type”) the initial speed extremely rarely exceeds 150 m/s, but this is done solely for safety reasons: such “weapons” are intended for military-tactical games and initially involve shooting at people, and the high speed would be unsafe for players even with protective equipment.

It is also wor...th considering that this indicator is not strictly defined. In any type of pneumatic it depends on the weight of the bullet (the lighter the faster); therefore, in the characteristics it is usually customary to indicate a certain average velocity for standard ammunition (usually weighing 0.5 g, in AEG - 0.2 g). In addition, in multi-compression rifles the actual speed of the bullet is determined by the degree of inflation, in gas-cylinder rifles it is determined by the ambient temperature, and in PCP models it is possible to achieve higher speeds than declared by replacing the air with a special gas (for example, helium). Nevertheless, this characteristic makes it possible to evaluate the capabilities of the rifle and compare it with other models, including those that differ in type.

The type of cocking system provided in the design of the rifle.

The cocking system is responsible for placing the trigger mechanism on the combat cocking (in the position of readiness for firing), and with a multi-shot design, it is also responsible for sending the next bullet into the chamber. Such systems are usually divided according to the method of control. Variants found in modern times include but are not limited to barrel fracture, lever ( side or underbarrel), pump action, bolt action (including varieties such as biathlon and bolt action), and autococking. Here are the main features of each of these systems:

— Fracture of the trunk. In rifles with this type of cocking, the barrel is fixed on a rotary axis, and folds down with each reload. In this case, not only the trigger is cocked, but the chamber is also opened, allowing you to load the next bullet. This option is found exclusively in spring models — conventional and with a gas spring (see "Type"), it is with such rifles that a barrel break is best compatible. One of the key advantages of such systems is their low cost. In addition, breaks are very easy to use, do not require special skills and are suitable even for inexper...ienced shooters. So such pneumatics are extremely popular nowadays. At the same time, it is usually made single-shot (with very rare exceptions), constant folding and unfolding of the barrel can be quite tedious, and the barrel mount tends to become loose as it wears, which reduces accuracy and power.

— Autoplatoon. Systems that do not require the shooter to take any additional actions to cock the weapon; found in PCP pneumatics (see "Type"), gas models, as well as AEGs (the latter, by definition, are made only by auto-cocking). In accordance with the name, a platoon in such weapons is carried out automatically before each shot — usually, with sending the next bullet into the chamber (although there are also single-shot models where the bullet must be inserted manually). Anyway, auto-cocking is extremely simple and easy to use. In addition, on the basis of such mechanisms, even fully automatic weapons can be created (see "Automatic mode"), although most rifles with this feature still work in the single-fire format. Among the disadvantages of such systems, one can note the complexity of the design and rather high cost, as well as the fact that air / gas is additionally consumed for the operation of the auto-cocking. This reduces the number of shots per charge, and can also reduce the initial speed compared to similar models with manual reloading (however, the latter is predominantly characteristic of gas-balloon rifles).

— Underbarrel lever. Systems that use a lever under the barrel, which must be pressed down with each cock. Like the barrel fracture described above, this method is used mainly with spring-piston mechanisms and gas springs. It is more convenient and reliable, since the barrel of the rifle constantly remains motionless, there are no fasteners in its design that can loosen up and fail. On the other hand, the lever design is noticeably more complicated and more expensive than the tipping one, and therefore is quite rare.
Note that the inflation lever in multi-compression models (see "Type") is usually not responsible for cocking the weapon, so a different cocking method is indicated for such rifles (although there are exceptions). And in gas-balloon models there is a special kind of underbarrel lever — the so-called Henry brace, as in classic cowboy hard drives (in fact, such pneumatics usually just copies this weapon).

— Side lever. Systems using a lever on the side of the rifle — usually on the right. They are found mainly in models with a spring-piston mechanism or a gas spring. As in the case of the underbarrel lever, the main advantage of this method can be called the immobility of the barrel, which contributes to accuracy and reliability. On the other hand, such a cocking system is usually made for right-handers and can be uncomfortable when firing from the left shoulder; in addition, the side lever is somewhat more difficult to fit into the design than the underbarrel. Therefore, this option is not widely used.

— Shutter. Systems using a classic type bolt handle — sliding back and forth. This cocking does not provide air pumping, and therefore is used only in gas-balloon type rifles, PCP, and some multi-compression models (see "Type"). Pneumatics with shutters are mainly made multi-charged — this is the very idea of \u200b\u200bsuch systems (feeding the next bullet from the magazine); however, there are exceptions. In general, this is a fairly simple, practical and reliable method of cocking, however, nowadays, more specific types of shutters are increasingly being used — biathlon and bolt; they are listed separately in our catalog and described below.

— Biathlon shutter. A variety of bolts (see above), copied from small-caliber biathlon rifles. In such systems, as in traditional bolt mechanisms, the cocking handle is located on the side and moves back and forth. The key difference is that this handle is mounted on a swivel mount and, when reloading, does not slide along the guides, but swings on the axis. The biathlon bolt differs from the side lever of a similar design (see above) in its location (in the rear of the rifle), the shorter lever length, and also in that it does not provide air pumping. Many shooters find this shutter more convenient than the classic one — in particular, it has a very small operating force, so you can move the lever without looking up from the sight. And in some models, for cocking, you don’t even need to remove the “shooting” hand from the handle — just hook the lever with your index finger, pull it towards you with a slight movement of your wrist, and then, if necessary, move it forward with your thumb. The biathlon action is used almost exclusively in PCP rifles (see "Type").

— Bolt lock. A kind of bolt (see above), which, when reloading, not only moves back and forth, but also rotates around its axis — similar to how it happens in many classic firearms like the Mosin rifle or Remington 700. Actually, the similarity with a real weapon this is precisely one of the key advantages of such systems: they are appreciated by fans of traditional rifles, and can also be good simulators for developing basic shooting skills from more serious "bolt" weapons. Most pneumatics with such cocking systems are PCP or gas-balloon, only a few models use the multi-compression principle (see "Type").

— Pump mechanism. Systems that use a movable handguard for cocking — like pump-action shotguns, hence the name. The main convenience of such systems is that cocking can be carried out without removing the hands from the weapon. On the other hand, the constant movement of the forearm knocks down the sight and adversely affects accuracy, so this method of cocking is not very popular in air rifles.

And in models like AEG (see “Type”) and other airsoft weapons, the capacity is indicated for the standard magazine supplied in the kit; in this case, the magazine, as a rule, is removable, and if desired, it can be replaced with another one that differs in capacity. It is worth noting here that airsoft magazines are usually divided into “bunkers” (high capacity) and “mechanics” (low capacity). Mechanas typically hold up to 150 pellets, and some of these magazines have the same capacity as real weapons. This variety is appreciated by lovers of realism and experienced players. In “bunkers,” in turn, the capacity is already hundreds, and sometimes thousands, of bullets. They are convenient for beginners and undemanding airsoft players, but a serious drawback of such magazines is noise - the balls, hanging in the main compartment of the “bunker”, turn it into a rattle, making it difficult to move covertly.

The number of shots that a PCP type rifle (see "Type") can fire on one full tank, and a gas-cylinder model — from one regular cartridge.

The larger this number, the less often you will have to be distracted by reloading a rifle or replacing a cartridge. On the other hand, an increase in the number of shots per charge has its downsides. So, in the case of PCP, for more shots on a charge, either a larger tank is needed (which affects weight, dimensions and cost), or a higher pressure in the tank (which can make refueling difficult and, again, affects cost). In LPG models using standard cartridges, more shots usually means less gas per shot and, as a result, less muzzle energy and muzzle velocity.

It is also worth noting that on the last shots of one refueling, the gas pressure and the effectiveness of the weapon are noticeably reduced; this effect is most pronounced on gas-ballooned rifles, least pronounced on PCP-models with air supply by a gearbox (see below). So the number of effective shots from one gas station will inevitably be less than the total number of shots.

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 dis...advantage 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 safety provided in the design of the rifle.

Recall that the fuse is a device that prevents an unwanted shot. In air rifles, such a device can be automatic or manual, and in some models it is absent altogether. Here are the features of each option:

— Manual. Fuse, switched on and off exclusively manually, at the will of the shooter. The most common variety — such mechanisms are as simple and inexpensive as possible. They are somewhat less safe than automatic ones (see below) and require more careful attention; however, it is not difficult to develop the skill to properly handle the manual safety. And in multi-shot models, the advantage of manual safety over automatic is that there is no need to make unnecessary actions between shots.

— Automatic. A fuse that, at a certain moment, works automatically, without additional actions on the part of the shooter. Most often, such systems operate in this way: the weapon automatically becomes on the safety lock after the trigger is cocked, and in order to make a shot, you must first turn off the safety lock manually. This provides more safety than in the manual systems described above: if the shooter forgets about the fuse, the shot will not happen anyway. Particularly popular are automatic safety locks in cocked rifles due to a broken barrel (see "Cocking System"): such a mechanism does not allow you to pull the trigger until the shooter has completed relo...ading. But in other types of pneumatics, this option is rare.
In addition, this category may include systems that are not fuses in the original sense of the word — for example, a mechanism that prevents the bullet from feeding into the chamber of a PCP rifle (see “Type”) if there is already a charge there.

— Is absent. No separate fuse. A similar design is found in two varieties of air rifles. The first is low-cost models with a spring principle of operation (including those with a gas spring; see "Type"). In such models, the fuse is abandoned solely to simplify and reduce the cost of construction; it is worth buying such a rifle only if the future owner knows the safety rules when handling weapons.
The second type of pneumatics without fuses are high-end PCP rifles designed for professional shooters. Similarly, the role of the "fuse" when using such weapons is played exclusively by the skills and experience of the user himself.

The ability to adjust the features of the trigger triggering of the rifle — first of all, the idle (before triggering) stroke of the trigger and the force on the hook. This allows you to optimally adjust the characteristics of the weapon to the personal preferences of everyone: for example, it is usually difficult for beginners to shoot with a tight trigger, but for trained shooters, a too soft hook that “falls through” under the finger may be inconvenient.
