Comparison Hatsan AirTact vs Hatsan Torpedo 105x

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 s...uitable even for inexperienced 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 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...parameter, and when choosing, it is better to focus on more "close to life" characteristics — first of all, directly claimed muzzle velocity.
