SPA B3-3

A light air rifle with a gas spring and an underbarrel cocking mechanism, which makes the model stand out from the hordes of "classmates" of a spring-piston type with a traditional barrel fracture. The stock of the rifle is made of natural wood; in order to prevent the weapon from slipping out of the shooter's hands when firing, longitudinal recesses are made on both sides of it in the place where the supporting hand grips.

SPA B3-3 is equipped with a steel rifled barrel and stock sights. The front sight and the aiming bar are equipped with coloured fibreglass threads, which allow accurate shooting at targets in poor ambient light conditions (for example, at dusk). The possibility of installing external sights is realized due to the presence of a standard dovetail mount in service with the model. Ammunition for air rifles are bullets of 4.5 mm caliber. They leave the barrel with an initial flight speed of about 175 m/s. The model does not have a fuse.
