Abstract
An action lock for a Modern Sporting Rifle pump action firearm is pivotably mounted within the lower receiver of the rifle and has a stop surface that engages a contact surface on the bolt carrier when the bolt carrier is in battery. A cam on the hammer or the trigger engages a cam surface on the action lock when the hammer is released by a pull of the trigger. Cam action rotates the action lock out of engagement with the bolt carrier, unlocking it and allowing the fore end grip to be pumped to cycle the action and extract and eject the spent casing and strip and chamber a new round.
