Magazine capacity
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.
Shots from one refueling
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.
Maximum pressure
The highest internal gas pressure that a PCP-type rifle cylinder can withstand without consequences (see "Type"). The maximum pressure in the cylinder does not fundamentally affect the characteristics of the rifle — models with the same value can differ significantly in muzzle energy, muzzle velocity, the number of shots at a gas station, etc. This parameter is indicated solely for safety purposes — in particular, so that the user does not “overdo it” when refueling: for example, in scuba cylinders used for this, the pressure can vary from 180 to 300 bar, while in most modern pneumatics the tanks are designed for 200 bar , and connecting more pressure is fraught with unpleasant consequences.
For comparison: the working pressure in a bicycle tyre is on average about 3-4 bar.
Storage capacity
Volume of the compressed air tank installed in the PCP rifle (see “Type”); if there are two tanks (see below), their total capacity is usually indicated.
A large tank allows for a greater number of shots per fill, but there is no strict dependence here: this number will also depend on the pressure in the tank, muzzle energy and some other specific factors. So in this sense, the tank capacity is purely for reference. But what it directly affects is the dimensions and weight of the weapon: a larger container will inevitably weigh more and take up more space. However, the latter drawback is often compensated for by the large length and small diameter of the reservoir - such a detail fits well into the proportions of the rifle.
As for specific volumes, they can vary up to 60 – 100 cm3 in relatively simple and inexpensive rifles up to 500 cm3 in high-end models; and if there are two tanks, their capacity can exceed 800 cm3.
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.
