Letter FThe Definition of Falling Block
Falling Block
A type of action used primarily for single shot rifles whereby some kind of lever actuates a breechblock, moving it downwards in a vertical recess to expose the chamber.
May have visible or enclosed hammer. For any given barrel length, it allows a shorter overall rifle length compared to a bolt action because no space is
taken up by the forward-and-back cycling of the bolt. Most of the better British makers produced them in limited numbers around the turn of the last century,
the Farquharson being the most iconic. Perhaps the best-known falling block action today is the Ruger No.1.
