Comparison Umarex NXG APX vs Crosman Benjamin 397

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.

The type of barrel fitted to the rifle.

This parameter is indicated by the type of the inner surface of the barrel, the options may be as follows:

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

— Smooth. Barrel with a smooth inner surface, without rifling. One of the main practical advantages of this design is "omnivory": smooth barrels can be used for both bullets and balls (although the specific type of ammunition used depends on the model of the rifle). In addition, a flat surface is noticeably easier and cheaper to manufacture than a grooved one. The main disadvantage of such a weapon is its rather low accuracy, since the projectiles fired from it are not stabilized due t...o rotation. Smoothbore rifles are designed primarily for recreational shooting at short distances; it is also worth noting that such barrels were originally used in airsoft drives, in particular, AEGs (see "Type").

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.

The type of ammunition the rifle is designed to use.

— Bullets. In this case, a bullet is called a directional projectile, with a clearly defined front and rear. The specific form of such projectiles may be different, but they all have a number of common features. So, any bullet at the same initial speed flies further and hits more accurately than a ball. And the material is usually lead or another soft metal, which provides a number of advantages. Firstly, bullets work great with rifled barrels (see "Barrel"): the edges of the bullet clearly fit into the grooves on the inner surface (many bullets are even able to slightly expand at the time of the shot, for the most dense fit in the barrel), the projectile is effectively spun and stabilized, while the wear of the rifling is minimal. Secondly, the bullets flatten out when they hit 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 disadvantages of bullets include perhaps a higher cost than that of balls.

— Balloons. Most of the models that use this type of ammunition are designed for airsoft and refer to AEG's (see "Type") or spring-piston ("spring" in airsoft jargon) rifles. The balls in this case are plastic, large in size, which reduces penetration and minimizes the likelihood of injury. Traditional air rifles for this type of ammunition are very rare. They use metal balls — usually steel with or witho...ut copper or zinc coating, less often lead. Such projectiles are distinguished by a very low cost and a good penetrating effect, however, they are noticeably inferior to bullets in terms of convenience and efficiency. First, the balls themselves are less accurate, they have more spread and lose speed faster. Secondly, 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 mentioned lead balls, 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 allow the use of both bullets and balls. See above for more information on each type of ammunition, but here we note that the main option in this case is still bullets; balls should be considered as a fallback. Usually, separate stores for different types of projectiles are supplied with such "omnivorous" 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 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 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.

— 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).
