Abstract (en)

A device controlling the breech-block of a shotgun, especially a 12-gauge shotgun, includes two cylindrical lined up inertial masses which are free to slide with respect to each other and to the shotgun along the tubular magazine located under the barrel, the mass remote from the shotgun butt being pivotally connected to a first class lever acting on the breech-block, the other mass being capable of moving said first class lever to release the- breech-block, the displacement of the first inertial mass being impeded by an elastic member or counter spring which is capable of being compressed against a solid member of the shotgun, when the recoil energy overcomes a predetermined threshold, so that the lever controlling the breech-block is driven by the second mass in a more or less delayed way depending on the power of the used cartridge. <IMAGE>
