In the modern arms market, a wide range of different shooting models is presented. The pneumatics are in great demand among consumers. PM 49 Borner is one of the most powerful wind guns. According to the owners, it can be confused with the militant Makarov. Description, device and performance characteristics of pneumatics PM 49 Borner are contained in the article.
Acquaintance
Pneumatics PM 49 Borner is a classic short-barreled weapon. The gun is equipped with a carbon dioxide filled siphon spray can. Steel balls with a diameter of 4.5 mm are used as ammunition in the pneumatics of PM 49 Borner.
Description
Externally, a wind gun is very similar to a combat Makarov. The pneumatic model is characterized by the presence of all the parts used in the legendary PM: a movable trigger guard, a safety lever, a lever that releases the delay, and a large trigger containing transverse notches. Like the Makarov pistol, the PM 49 pneumatics undergoes a burnishing procedure. Combat and wind shooting models have the same matte gloss. In addition, the pistols are equipped with similar plastic handles. Unlike PM, the wind version is not made of weapon steel, but of a special silumin alloy.
About device
The gun is equipped with a 4.5 mm steel fixed barrel. For the pneumatic model, barrel rifling is not provided, as well as the Blowback effect. The design of a wind weapon is characterized by an imitation of a lever that performs a delay release. Despite the fact that the designers made the trigger guard movable, it does not fulfill its function. The mechanics of the pistol is adapted for gas firing. The pneumatics were equipped with a 12-gram siphon, the place for which was the handle of the pistol.
There is also a clip with ammunition. It is equipped with 17 steel balls, which may have a copper or zinc coating. Unlike the PM Umarex Ultra, the Borner PM 49 does not provide a combination in the grip of the holder and cartridge. A gas can is installed according to the standard scheme - by shifting the plastic pads back. There is no clamp screw screw. Instead, the pneumatic equipment was equipped with a hexagonal slot. It is removed using the L-shaped key, which goes to the PM 49 pneumatics repair kit. The air gun is equipped with a trigger designed for double action. Shooting is carried out in two ways: after pressing the hook with self-cocking, or after cocking the trigger every time before firing. Judging by the reviews of the owners, applying the second option, you have to spend much less effort. There are two strokes for the trigger in the design of the gun: preliminary and working. The gun is equipped with standard sights: whole and front sight, the space between which became the place for the location of a special strip. Its task is to prevent the occurrence of glare during aiming.
About the principle of action
Pneumatics PM 49 is equipped with a special expansion chamber, which is filled with gas. The design of the gun has a bypass valve with a stem. The hammer blow on him occurs after his breakdown from a whisper. Using a special plastic nozzle, the developers connected the barrel with gas fittings. Of all spare parts for pneumatics PM 49 Borner, this nozzle is the only non-metallic. Also connected to each other back chamber and clip. After pulling the trigger, the trigger hits the rod, as a result of which, in the bypass valve, with the help of a movable needle, the ammunition moves into the barrel channel.
The gun is not equipped with any buttons and levers for removing the clip from the handle. It is removed by pressing the special latch. Reliable fixation of the handle in the cage provides a special slot. In an effort to protect the owner from accidental firing, the designers equipped the pneumatic with a flagged mechanical fuse, for which there are two positions: “fire” and “stop”. In order to make a shot, the flag needs to be moved up.
