In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon. The sear may be a separate part or can be a surface incorporated into the trigger.

Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber.This is accomplished by actuating a striking device through a combination of mainspring (which stores elastic energy), a trap mechanism that can hold the spring under tension, an intermediate mechanism to transmit the kinetic energy from the spring releasing, and a firing pin to eventually strike ...

It is basically an internal trigger actuated by the bolt/bolt carrier when placed in-battery. An auto sear is required in nearly every automatic rifle.
The sear is a "catch" or "latch" which holds the mechanism in a position ready to fire; the trigger acts upon, or is part of, the sear, releasing it and allowing a strong spring to act on the mechanism to fire the gun. Previously the sear, located within the lock, had acted through a hole in the lockplate to engage the cock on the outside of ...
The movement of the sear is nominally parallel to the axis of rotation of the cock. Depressing the trigger causes the sear to be drawn inward and release the cock. This type of sear was used in firelocks prior to the advent of the true flintlock. The next advance in firearm design was the snaplock, which used flint striking steel to generate ...
