Muzzle velocity

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.

Cocking system

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

The cocking system is responsible for setting the trigger mechanism to the combat cocking position (ready to fire), and in the case of a multi-shot design, also for feeding the next bullet into the chamber. Such systems are usually divided by the control method. The options encountered today include, in particular, a barrel break, a lever ( side or under-barrel), a pump mechanism, a bolt(including such varieties as biathlon and bolt), and an automatic cocking system. Here are the main features of each of these systems:

— Barrel break. 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 mechanism is cocked, but the chamber also opens, 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 the barrel break is most 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 inexperienced shooters. So such pneumatics...are extremely popular these days. At the same time, they are 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 loosen as it wears out, which reduces accuracy and power.

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

— Under-barrel lever. Systems that use a lever under the barrel, which must be pressed down with each cocking. Like the barrel break described above, this method is used primarily with spring-piston mechanisms and gas springs. It is more convenient and reliable, since the rifle barrel remains stationary at all times, and its design does not include fasteners that can become loose and fail. On the other hand, the lever design is noticeably more complex and expensive than the break-action design, and therefore is quite rare.
Note that the pumping lever in multi-compression models (see "Type") is usually not responsible for cocking the weapon, so a different cocking method is specified for such rifles (although there are exceptions). And in gas-cylinder models, there is a special type of under-barrel lever - the so-called Henry bracket, like in classic cowboy Winchesters (in fact, such pneumatics usually just copy this weapon).

— Side lever. Systems that use 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 an under-barrel lever, the main advantage of this method is 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 inconvenient when shooting from the left shoulder; in addition, a side lever is somewhat more difficult to fit into a design than an under-barrel lever. Therefore, this option has not become very popular.

— Bolt. Systems using a classic type of bolt handle — sliding back and forth. This type of cocking does not provide air pumping, and therefore is used only in gas-cylinder rifles, PCP, and some multi-compression models (see "Type"). Pneumatics with bolts are mainly made multi-shot — this is the very idea of such 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, but nowadays more specific types of bolts are increasingly used — biathlon and bolt; they are listed separately in our catalog and described below.

— Biathlon bolt. A type of bolt (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 fixed on a rotating mount and does not slide along the guides when reloading, but swings on the axis. The biathlon bolt differs from the similar in design side lever (see above) in its location (at the rear of the rifle), shorter lever length, and the fact that it does not provide air inflation. Many shooters consider this bolt more convenient than the classic one — in particular, it has a very small operating force, due to which you can move the lever without taking your eyes off the sight. And in some models, you don’t even need to remove your “shooting” hand from the handle to cock the bolt — just hook the lever with your index finger, pull it towards you with a light movement of the wrist, and then, if necessary, move it forward with your thumb. The biathlon bolt is used almost exclusively in PCP rifles (see "Type").

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

— Pump mechanism. Systems in which a movable fore-end is used for cocking — as in pump-action shotguns, hence the name. The main convenience of such systems is that cocking can be done without removing your hands from the weapon. On the other hand, the constant movement of the fore-end throws off the sight and has a negative effect on accuracy, so this cocking method is not particularly popular in air rifles.

Barrel

The type of barrel installed in a rifle.

This parameter is specified according to the type of the inner surface of the barrel, the options can be as follows:

Rifled. A barrel with spiral grooves applied to the inner surface. This is the most popular option among modern air rifles — in fact, the term “rifle” itself comes from the helical rifling in the barrel. Thanks to the internal rifling, the bullet flying out of the weapon twists around the longitudinal axis, which ensures a stable trajectory and improves shooting accuracy. The only disadvantage of this type of barrel is its poor suitability for working with balls: there are relatively few rifled rifles compatible with these types of ammunition, and it is best to use special balls made of lead or other soft material with them (traditional steel balls wear out the rifling a lot). However, this point cannot be called a serious drawback.

Smooth. A barrel with a flat inner surface, without rifling. One of the main practical advantages of such a design is its "omnivorousness": smooth barrels can be used for both bullets and balls (although the specific type of ammunition used depends on the rifle model). In addition, a flat surface is noticeably simpler and cheaper to produce than a rifled one. The main disadvantage of such weapons is their rather low accuracy, since the projectiles fired from them are not stabilized by r...otation. Smooth-bore rifles are intended mainly for recreational shooting at short distances; it is also worth noting that such barrels were originally used in airsoft guns, in particular, AEGs (see "Type").

Charging

Load capacity determines the amount of ammunition that can fit in a rifle's magazine at one time.

Single shot. As the name suggests, these rifles can only hold one bullet, usually directly in the chamber (back of the barrel); You have to reload your weapon after every shot. This is not very convenient due to the need for additional manipulations, and the rate of fire suffers significantly. At the same time, single-shot rifles are usually quite simple in design, which ensures, on the one hand, reliability, and, on the other hand, low cost.

Multi -charged. Rifles that can hold multiple bullets or pellets in a single charge. For their placement, special devices are used — removable or non-removable stores, drums, etc. The capacity is usually between five and several dozen rounds of ammunition. At the same time, for "omnivorous" models (see "Type of ammunition"), the capacity for balls is usually higher than for lead bullets — often 2-3 times; there are even options that are multiply charged only when using balls — bullets in them can only be loaded one at a time. The advantage of a multi-shot weapon over a single-shot weapon is obvious: you can fire several shots from it without being distracted by reloading. Reloading itself, if more difficult, is not much. On the other hand, due to the complexity of the design, such models are significantly more expensive; and in some types of pneum...atics (see above), multiply charged is not applicable by definition.

Type of ammunition

The type of ammunition that the rifle is designed to use.

— Bullets. In this case, a bullet is a projectile of a directional shape, with a clearly defined front and back. The specific shape of such projectiles may be different, but they all have a number of common features. Thus, any bullet with the same initial speed flies further and hits more accurately than a ball. And lead or another soft metal is usually used as a material, which gives a number of advantages. Firstly, bullets work great with rifled barrels (see "Barrel"): the edges of the bullet fit neatly into the grooves on the inner surface (many bullets are even able to slightly expand at the moment of firing, for the most dense placement in the barrel), the projectile effectively spins and stabilizes, while the wear of the rifling is minimal. Secondly, bullets flatten when hitting a more or less hard surface - this minimizes the risk of ricochets and allows the use of such ammunition even when hunting fairly large game. The only disadvantage of bullets is their higher cost than balls.

— Balls. Most models using this type of ammunition are intended for airsoft and are AEGs (see "Type") or spring-piston ("spring" in airsoft jargon) rifles. The balls in this case are plastic, large in size, which reduces the penetration ability and minimizes the likelihood of injury. Traditional air rifles for this type of ammunition are very rare. They use metal balls - usually made of steel with or without a...copper or zinc coating, less often made of lead. Such shells are very inexpensive and have good penetration, but are noticeably inferior to bullets in terms of convenience and efficiency. Firstly, the balls themselves are less accurate, they have a greater spread and lose speed faster. Secondly, the hard metal makes it difficult to use with rifled barrels, which, again, further reduces accuracy. Thirdly, due to the same hardness, steel balls often ricochet. The last two points are not relevant for the lead balls mentioned, but they are much less common than steel ones. So, in general, this type of ammunition can be recommended for recreational shooting at short distances - up to 10, less often up to 20 m.

— Lead bullets/balls. Rifles that accept both bullets and balls. For more information on each type of ammunition, see above, but here we note that the main option in this case is still bullets; balls should be considered a backup option. As a rule, such "omnivorous" rifles are supplied with separate magazines for different types of projectiles.

Scope mount

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.

Adjustable trigger

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.

Barrel length

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.

Stock material

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 materia...l 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).
