Abstract
A gun includes a barrel arranged to execute a recoil and a counterrecoil after a shot is fired; a trunnion about which the barrel is pivotal in a vertical plane to assume an index position and firing positions situated at an angle to the index position; a case ejector for ejecting a case from the barrel during counterrecoil; and a counterrecoil blocking device for interrupting the counterrecoil as long as the barrel is in a firing position other than the index position and for allowing the counterrecoil to resume when the barrel assumes the index position, whereby case ejection by the case ejector is effected in the index position.
