Rolling Block - A type of action, normally confined to 19th century single shot rifles, especially by Remington, where cocking the hammer releases a hinged breechblock to be swung back easily and to expose the chamber. When the hammer moves forward, its underlying cam locks the hinged breechblock in battery just prior to discharge.
