Finishingõlina

Finishingõlina is a term used to describe a specific type of sound produced by certain types of firearms during the firing cycle. It is characterized by a high-pitched, often rapid, whirring or buzzing noise that occurs immediately after the projectile has left the barrel. This sound is distinct from the primary muzzle blast or the mechanical action of the firearm.

The exact cause of finishingõlina can vary depending on the firearm's design and ammunition. It is generally believed to be related to the rapid expansion and escape of gases through small openings or imperfections in the barrel or muzzle device. Factors such as the rifling, the presence and type of a muzzle brake or suppressor, and the precise tolerances within the barrel can all contribute to its production.

While not a functional defect, finishingõlina can be perceived as an undesirable trait by some firearm enthusiasts and users. Efforts to reduce or eliminate this sound may involve modifying or replacing muzzle devices, or in some cases, using specialized ammunition. The sound itself does not typically indicate a safety concern or a malfunction, but rather a specific acoustic phenomenon. The term is most commonly encountered in discussions and reviews of certain semi-automatic pistols and rifles.
