ABSTRACT:
Automatic or semiautomatic firearms which operate on the blowback principle are equipped to fire more powerful cartridges by the provision of a simple lightweight mechanical recoil movement delaying mechanism which increases the breech opening delay time so that the higher gas pressure in the weapon's firing chamber resulting from the use of more powerful cartridges will have time to drop to a safe level. A second embodiment of the recoil movement delaying mechanism is employed to provide a simple inexpensive locking device for use on automatic or semiautomatic firearms which operate on the locked breech principle.
