摘要： The invention relates to a gas piston for a weapon, which is characterized by a spring introduced in the gas piston and a plunger, which engages on one end of the spring, wherein the spring is supported by the other end at the end of the gas piston opposite the plunger. This gas piston can be a component of a gas piston assembly having a counter piston, which is for use in a weapon. The gas piston or the plunger is supported e.g. on the weapon housing. With the special construction of the gas piston or the gas piston assembly formed with same, the gas piston can be transferred from a working position into a resting position within a weapon housing of the weapon.

摘要： A projectile with a projectile casing and at least one pyrotechnic charge incorporated in the projectile casing is proposed, wherein the projectile has an open projectile base with a destructible membrane and the pyrotechnic charge burns away at a defined rate during the flight of the projectile, and so the projectile loses mass in such a way that a predetermined effective range is not exceeded. As a result, safety and a nonlethal effect are achieved, in particular outside the effective range.
