Abstract: A compressed-gas-operated firearm, comprising a reservoir for compressed gas; valve means (8) for supplying the compressed gas from the reservoir to a projectile (10) to which the compressed gas is to be applied, in which case the valve means (8) can have an impulse applied to it, at least in places, for firing a shot; in which case the valve means (8) are designed such that, by replacement of at least one first part by at least one second part of the valve means (8), the amount of compressed gas which is available for the acceleration of the projectile (10) per shot and/or the pressure of the compressed gas which is available for application to the projectile (10) can be varied.
