A device for firing projectiles without recoil and without a signature has a barrel (1) which is constructed to be open on both sides and is provided both in the region of the muzzle and the rear with stops (4, 5). A braking ring (12), the projectile (13) to be fired, a sabot (14), a propulsion charge (15), a further sabot (16), an inert mass (17) which can be dispersed well and a further braking ring (18) are arranged axially one behind the other in the barrel. In order to prevent danger to the operating personnel as a result of forces which cannot be contained during the braking of the sabots (14, 16), the sabots (14, 16) are provided with a bell-shaped recess (19, 20), the inclination ( phi A, phi E) of the first steeper section (21) of the bell-shaped recess (19, 20) being dimensioned such that the braking force (P) which is produced by the deformation of the braking ring (12, 18) is less than the critical buckling force (PBcrit) of the braking ring (12, 18).
