recoil(redirected from recoiler)
Also found in: Dictionary, Thesaurus, Medical, Legal, Idioms.
in firearms, the reverse movement of the barrel or breech caused by the energy of the powder gases when a pistol, rifle, or artillery gun is fired. The movement goes in the direction opposite to the direction of firing.
Recoil is manifested as a force that affects the firer or gun mount. In automatic weapons, the recoil is used for reloading (opening the breech, ejecting the used cartridge, loading the next round, closing the breech, and setting the firing pin).
