Locking device for movable momentum connection in suppressors for semi-automatic and fully automatic weapons

Abstract

The devices and assemblies of the invention allow the design and use of suppressors with at least two modes of operation and the suppressor can be reset significantly faster and more simply from a locked position into an unlocked position. The suppressors of the invention comprise a mounting ring and a momentum part or assembly that can be shifted axially, or along the axis of the barrel of the weapon. A pressure spring is positioned between it and a column sleeve of the silencer, which on the one hand presses the momentum part against a projection of the column sleeve and on the other hand against the index disk. Interlocking cams are positioned on the momentum part, which are blocked in a first position of the mounting ring, and in a second position of the mounting ring they can be shifted so that the momentum part is unlocked and can move axially in response to firing. Rotating the mounting ring allows the operator to switch from the first position into the second position, and lock or unlock the momentum part and the recoil booster function of the devices.
