What does the Sear do?

Hi Warren,

The sear engages the firing pin and holds it in a cocked position until the trigger is pulled. Note the long flat bar that runs along the left side of the receiver that actuates when the trigger is pulled, this is the sear bar.

When the trigger is pulled it compresses the L shaped trigger lever in the side plate, which causes it to press on the sear bar, causing the sear bar to pivot inward releasing the firing pin. The sear is the portion of the sear bar that engages the small square "tab" on the side of the firing pin.

Hope I have made this clear enough to understand.
