Comparison Gamo Swarm Magnum Pro 10X Gen3i vs Magtech N2 Extreme 1300

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 muzzle energy provided by the rifle.

Muzzle energy is the kinetic energy of the bullet at the exit from the barrel. This energy, in turn, depends on two factors: the mass and the muzzle velocity of the bullet. Thus, this indicator directly describes the overall power of the rifle: higher muzzle energy allows you to effectively fire at longer distances and/or heavier ammunition. On the other hand, an increase in power accordingly affects the cost of weapons.

Note that muzzle energy can be grounds for legal restrictions on the purchase/use of pneumatics. So, in some countries in the post-Soviet space, the maximum value allowed for freely sold rifles is 7.5 J — a special permit will be required to purchase more powerful weapons. And most freely sold rifles in such regions have a power of the order of 3 – 5 J. Such legal restrictions should be clarified separately. Lower rates are found mainly among “soft” pneumatics for airsoft (airsoft), using 6 mm plastic balls. For such models, a value of more than 2 J is already considered very solid, and in games such rifles are used with a minimum distance limit — for example, 15 m or 20 m (so that a shot from too close a distance does not injure the player).

It is also worth saying that the claimed characteristics of air rifles may, at first glance, not correspond to physical calculations. For example, for a model for the same 7.5 J..., the initial speed of 250 m/s can be claimed in the characteristics; for a 4.5 mm bullet weighing 0.5 g (the average, most popular weight), this would correspond to an energy of as much as 15.6 J. However, there are no inconsistencies here: such characteristics mean that the muzzle velocity was measured for a lighter bullet (for example, 0 .2 g), which accelerates more strongly at the outlet of the barrel. Accordingly, with heavier ammunition, the speed will be lower; it can be determined using special formulas or online calculators.

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.

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 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 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.

The ability to manually adjust the parallax in the complete optical sight of the rifle.

For sights of this type in general, see "Aiming Device". Parallax is a phenomenon that occurs when the shooter's eye is not on the optical axis of the sight (in other words, not strictly in the centre of the eyepiece). In such cases, the reticle in the eyepiece may also shift, and its apparent position may not coincide with the actual aiming point. To eliminate this effect, parallax adjustment is applied.

Any optical sight undergoes such adjustment at the factory. However, the physical features of this phenomenon are such that parallax can only be adjusted for a certain distance to the target; with significant deviations from this distance (more than 30% downward or 60% upward), parallax again begins to appear. So if you plan to use weapons at different distances, then it is best to have a sight on it with manual detuning from parallax. At the same time, it is worth noting that the complete optics in air rifles are usually adjusted to relatively short distances — at which these weapons are used; and deviations from these distances are rarely significant. Therefore, the parallax adjustment in standard pneumatic sights is rare — mainly among powerful long-range models that can deal with a wide variety of distances.

The diameter of the mounts that the complete optical sight of the rifle is equipped with. For optics in general, see Sights. And the diameter of the mounts is the diameter of the rings in which the tube of the sight is fixed. These rings are mounted on brackets, with which the entire structure is attached to the rifle.

In the vast majority of cases, the diameter of the rings is a purely reference parameter that does not affect the choice. Before buying a rifle, this data may be needed if the "household" already has another optical sight, which may be used instead of the standard one. And even in such cases, usually, it is easier to use the "native" mounts of a spare sight than to install it in the rings from the complete optics.

Also note that the vast majority of pneumatics with optical sights use mounts of a standard diameter — 25.4 mm. Other values (for example, 19 mm) are extremely rare.
