Blow forward is a firearm action where the propellant gas pressure and the friction of the bullet traveling down the bore drag the whole gun barrel forward to facilitate the opening of the breech.[1] This forward barrel motion provides most of the energy required to eject a spent cartridge case and chamber a fresh round of ammunition, and contains a minimum of moving parts, and thus is more compact than other operating mechanisms of equal barrel length.
