Comparison Beeman Longhorn Gas Ram (4x32) vs Beeman Longhorn 4x32

The type describes the basic operating principle of the rifle. Nowadays, you can find pneumatics with a spring-piston operating principle (with a regular or gas spring), with pre-pumping (PCP), with pumping before each shot ( multi-compression rifles), with power from 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 mechanism of such rifles is based on a spring-loaded piston moving in a cylinder. The weapon is cocked manually (usually by a lever or by breaking the barrel), with the piston being pulled back and fixed, the cylinder being filled with air, and when the trigger is pulled, the piston is released and moves forward under the action of the spring, pushing the air out of the cylinder into the barrel. Rifles of this type are distinguished by their simple and reliable design, low cost, low maintenance, and ease of repair and tuning; they are considered an ideal option for beginner shooters, as well as for fans of entertaining short-range shooting, and there are also airsoft models 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 insensitivity to he...at and cold. On the other hand, such rifles require cocking (and most often reloading) before each shot, which can be quite tiring; and the operation of the piston mechanism creates a specific recoil, which negatively affects accuracy and complicates the search filter of optical sights (special optics are required, originally intended for such use). In addition, this type of pneumatics cannot be kept charged for a long time - with prolonged compression, the mainspring loses its properties.

— With a gas spring. In general, the operating principle of this type of rifle is similar to the spring-piston rifles described above. The difference is that instead of a conventional metal spring, they use a sealed reservoir with a special gas, which acts as a spring — compressing when cocked and expanding when fired. This design has a number of advantages over a conventional spring-piston rifle. Firstly, the entire mechanism operates much smoother and quieter, and the recoil is softer, which improves accuracy and simplifies the search filter of optics. Secondly, the gas spring does not change its properties as it wears out, and such a weapon can be stored even in a cocked state. Thirdly, repairs and maintenance for gas springs are required less often and are cheaper (in terms of the number of shots between visits to the workshop). The disadvantages of this type of rifle, in addition to the need to cock the spring before each shot, include a slightly higher cost than classic spring-piston rifles, as well as sensitivity to cold: as the temperature drops, the gas pressure in the spring decreases, which reduces efficiency.

— PCP (pre-pumping). The source of energy in rifles of this type is a built-in reservoir containing air (or another gas) under very high pressure — about 200 or even 300 atmospheres. This reserve is enough for at least several dozen shots, and a compressor, a scuba tank or a special high-pressure pump can be used to fill the reservoir (sometimes such pumps are even supplied in the kit). In general, PCP is considered the most advanced type of pneumatics; it is these rifles that professional hunters and sportsmen use. This is primarily due to the fact that such a design allows for a very high bullet speed, and the recoil is almost imperceptible — all this allows for accurate shooting even at long distances. With a fresh gas, the rifle gives excellent repeatability of shots; however, as the gas is consumed, the initial speed of the bullet decreases, but advanced models may be equipped with a reducer that compensates for this phenomenon (for more details, see "Air supply with a reducer"). PCP pneumatics can be easily made multi-shot and provide very simple and convenient ways of feeding the next bullet into the barrel. The main disadvantage of such rifles is the high price.

— Multi-compression. Another type of rifle with a built-in reservoir; however, unlike the PCPs described above, the reservoir must be pumped up before each shot. For this purpose, the design provides a built-in pump controlled by a lever or other similar device; to pump in a sufficient amount of air, as a rule, you need to make several movements. Such rifles have virtually no recoil, while they are noticeably simpler and cheaper than PCP pneumatics, but inferior to it in power. In addition, pumping up the reservoir before each shot is quite a tedious task; and the volume of air supplied to the reservoir with each filling (and, accordingly, the working pressure in the reservoir) 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 the maximum bullet speed is not required, you can pump the rifle not completely in order to save energy. On the other hand, the actual volume of air and pressure in the reservoir will be slightly different with each reload, even with the same number of lever movements. This has a negative effect on the repeatability of shots. Due to this combination of features, multi-compression models are not very popular these days, and their purpose is mainly recreational shooting.

— Gas cylinder. A type of pneumatics that operates from replaceable gas cylinders, usually liquefied carbon dioxide. Like PCP, such a reservoir allows you to make a lot of shots — even a traditional 12-gram cylinder is usually enough for several dozen; and some models use containers for 88 g of carbon dioxide. At the same time, the rifles themselves are cheaper than PCP, but 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 liquid carbon dioxide remains in the cylinder. On the other hand, the actual gas pressure depends on the ambient air temperature, and the initial velocity of the bullet in such pneumatics can change significantly even with daily temperature fluctuations. And one of the clear disadvantages of such rifles is that you have to buy not only bullets for them, but also gas.

— AEG (electrically driven). Pneumatics that use an electric motor drive as a source of energy. In terms of the design of the working mechanism, it is similar to a spring-piston one — the basis of this mechanism is a cylinder and a spring-loaded piston. However, in this case, the piston is not pulled back manually, but with the help of the aforementioned electric motor. For the shooter, this means, first of all, that the rifle does not need to be cocked by muscle force — to fire, it is enough to press the trigger, the electric motor will do the rest. In addition, in such pneumatics, an automatic shooting mode can be easily provided (see below). Note that for a number of reasons, this operating principle is practically not found in traditional pneumatics, but it is very popular in airsoft models; such rifles ("drives") often copy real combat weapons.

The type of sighting device that the rifle is initially equipped with. Note that many models allow the installation of other sights - in addition to the standard sighting devices or to replace them. And optics or a 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, you can find diopter, optical and collimator sights in air rifles, and in some models, standard sighting devices are completely absent. Here are the features of each of these options:

— Sighting bar and front sight. Devices in the form of a front sight and a rear sight, which looks like 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 extremely simple, inexpensive, compact and reliable, and do not depend on batteries and are quite resistant to impacts and vibrations. In addition, the front sight with a bar does not limit the view as much as optics or a collimator, and is better suited for shoo...ting at moving targets. The main disadvantage of this option is that a certain skill is required for effective aiming - after all, you need to control not only the aiming at the target, but also the relative position of the front sight and the slot. On the other hand, this point can also be an advantage - in particular, when learning to shoot: having learned 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 and rear sight do not provide any magnification - this makes it difficult to shoot at small and / or distant targets; however, again, this feature is not always an unambiguous disadvantage.

— Diopter sight. A type of mechanical sighting device (i.e. front sight and rear sight) that uses 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 bar with a slot, especially for beginners: even without special skills, the shooter subconsciously chooses a position of the eye in which the front sight will be in the center of the hole (as it should be when aiming). In addition, a small hole gives a slight magnification effect and increases the clarity of the target contours, which is especially important at significant distances. On the other hand, diopters significantly limit the view, are poorly suited for low-light conditions and are easily clogged with various contaminants. Therefore, this type of sight is extremely rarely used in airguns - mainly in powerful long-range rifles, primarily for sporting purposes.

— Optical sight. Traditional optical sights in the form of a "spyglass" with a reticle applied to the shooter's field of view. Initially created for high-precision shooting at long distances, mainly at stationary targets; pneumatics are also used in the same role. True, not every pneumatic rifle with optics is a powerful long-range weapon - there are also relatively "weak" models. But even such pneumatics can be a good training aid in high-precision shooting: a short distance in this case can be compensated for by the small size of the target. 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 examine small targets, but at the same time limit the field of view. It is also necessary to take into account that the optics are not well suited for off-hand shooting and require careful insertion: the eye must be located 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, crosshair, circle with a dot, etc. Sights of this type usually do not have magnification and are intended for shooting at short distances, including at moving targets and offhand. So in use, a collimator is similar to a front sight with a rear sight; and its key advantage is its ease of use: there is no need to combine the front sight and the notch, it is enough to find the aiming mark in the window and point it at the target. At the same time, unlike optics, it is not necessary to keep your eye strictly opposite the center of the sight: the parallax effect (see "Adjusting the parallax") in collimators is very weakly expressed, or even absent altogether. The main disadvantage of this type of sight is that they require batteries to operate; In addition, collimators are significantly more expensive than traditional mechanical sights and also require more careful handling (although they are still less delicate than optics).
It is worth noting that such devices are especially popular in airsoft airguns, such as most AEGs (see "Type"): collimators are great for dynamic combat.

— None. The absence of any sighting devices in the original delivery set — there are only mounts for installing such devices. For more information on the different types of mounts, see below; here we note that such a complete set does not allow you to use the rifle "out of the box", but it does give you the opportunity to choose a sight for it at your own discretion, without relying on the manufacturer's choice. This is especially important if you plan to use optics — nowadays a wide variety of such sights are produced for different tasks and scenarios of use. In fact, most air rifles without a sight are designed specifically for installing optics, although the use of 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 gas piston models have a specific double recoil that not every scope can withstand - even if it allows use 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 scopes originally designed for such rifles.

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.

The working length of the rifle barrel is from the chamber where the bullet is loaded to the muzzle. The shortest barrels found nowadays have a length of just over 200 mm(and in some AEGs even less than this value); the longest reach 500 – 600 mm.

There is a stereotype that the muzzle velocity directly depends on the length of the barrel. In firearms, this is true — but not in pneumatics. Firstly, in such rifles, the initial velocity depends on a number of other indicators — pressure, the quality of the barrel treatment, the efficiency of the valves, etc. on the first 20 – 25 cm of the barrel, then the gas pressure drops noticeably. The exception is PCP rifles, in which the longer barrel really makes it easier to achieve high speeds. However, again, so many additional factors affect the final result that models with the same barrel length can differ markedly in initial speed.

The second common stereotype is that a longer barrel improves accuracy and accuracy. This is true in the context that a longer barrel allows for a greater distance between the front and rear sights, making it easier to aim carefully. Technical accuracy does not depend on the length, but on the quality of the barrel processing.

Summing up all of the above, we can say that the length of the barrel for an air rifle is more of a reference than a really significant paramete...r, and when choosing, it is better to focus on more "close to life" characteristics — first of all, directly claimed muzzle velocity.
