Abstract
A rifle lower receiver has a trigger well and a magazine well. A hammer is disposed in the trigger well and configured to pivot from a first hammer position to a second hammer position in response to moving a trigger from a first trigger position to a second trigger position. A gear member attached to the lower receiver has a predefined number of gear teeth and a locking pin extending from the gear member. A pawl is connected to the trigger and operationally engages the gear member to increment the gear member once per trigger pull. Upon reaching a predefined number of trigger pulls, the locking member locks the trigger. A release lever on the lower receiver is operably configured to advance the gear member one increment to unlock the trigger. A method of dry-fire training is also disclosed.
