Glossary
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.
