Abstract
A breech lock mechanism for automatic firearms, in particular, a rigidly closing breech lock mechanism with loosely located support flaps in its breech head which will slide along an associated and complementary formed latching and unlatching component into its rearward latching position during the opening of the breech lock mechanism. The surfaces of the support flaps which face towards the latching and unlatching component are at least partly provided with a lubricating layer whose hardness is different with respect to the complementary latching and unlatching component.
