Abstract
A breech mechanism for automatic firearms having a high cadence; and, in particular, a rigidly closing breech mechanism which includes a gas piston effecting the opening thereof and which stands in communication with a sleeve, a coil spring concentrically positioned interiorly thereof which is stressed upon the opening of the breech mechanism and which will conduct a latching and unlatching component into its closing position upon release of the energy stored therein. The gas piston as well as the closure spring each have a shock absorber associated therewith. The shock absorbers essentially consist of loose, stacked discs, plates or the like of high rigidity and toughness, whose surfaces incorporate production-caused uneveness.
