A schematic of the lever-delayed blowback mechanism used in the FAMAS assault rifle. Lever-delayed blowback utilizes leverage to put the bolt at a mechanical disadvantage, delaying the opening of the breech. When the cartridge pushes against the bolt face, the lever moves the bolt carrier rearward at an accelerated rate relative to the light bolt.

In some forms of delayed blowback, the rotating bolt is used as the delay mechanism: the bolt head rotates as the firing pin strikes, locking the chamber until the gas pressure reaches a safe level to extract.
