The present invention is related to hammer and hammer spring assembly from firearms especially but, not limited to, Stoner Automatic Rifle (SAR) variants, other firearms and other non-firearm mechanisms. The system and method is intended to relieve the hammer spring pressure during removal and installation the hammer. This is accomplished by capturing the hammer and spring legs onto a retainer which holds the spring legs in a position that does not engage any of the nearby features and allows the hammer, spring and retainer to float freely as one assembly on the hammer rotating pin. The system may utilize different shape retainers for other spring shapes and the spring spoon may have other cavity shapes to facilitate manipulating spring legs that are formed to engage on or over pins or other features for use in other firearms or non-firearm assemblies.
