Re: Ar15 stage2 trigger
The factory single stage trigger mechanism releases the hammer (firing the weapon) after a steady squeeze is applied by the trigger finger. This trigger squeeze requires steadily increasing pressure to overcome the sear spring and mechanical resistance. The "creep" inherent in the factory single stage trigger requires that the shooter take time to "walk" through the trigger pull and find the "let-off point" in order to achieve accurate fire. In the semi automatic mode the two-stage trigger mechanism releases the hammer (firing the weapon) after two distinct amounts of spring and mechanical resistance are overcome by the trigger finger. The Initial stage of resistance encountered with this design feels light and is relatively long - approximately I/8 of an inch. The second stage of resistance feels noticeably greater but is of very short duration. The result is an extremely predictable, consistent, "crisp" trigger pull; semi-automatic fire is both quicker and more accurate because the first stage is quickly overcome and the second stage is crisp and predictable.
