The Field patent falling-block action is most commonly found on rifles and W.W. Greener, in The Gun and its Development observed that 'the mechanism has proved efficient in arms of all sizes from .320 to .577 Express'. Unlike most other falling-block actions, the lever is pushed forward to depress the breech-block and cock the hammer. It is not known how many smooth-bore guns were built with this action, but it is most unusual to encounter a wildfowling-gun built in this way.
