Lever-delayed blowback
From Wikipedia, the free encyclopedia
Lever-delayed blowback is a form of blowback action in firearms. It uses a two-part bolt consisting of a lighter bolt connected via a lever to a heavier bolt carrier. When a round is fired, the cartridge pushes against the bolt face that moves the delay lever upwards so the heavy bolt carrier moves back at an accelerated rate relative to the light bolt. This increases the resistance on rearward movement of the bolt and allows for a lighter operating mechanism than would be necessary without the mechanism.
The mechanism was invented by Hungarian arms designer Pál Király [1] in the 1930s and first used in the Danuvia 43M submachine gun.
