A falling-block action (also known as a sliding-block or dropping-block action) is a single-shotfirearm action in which a solid metal breechblock slides vertically in grooves cut into the breech of the weapon and is actuated by a lever.[1]
When the breechblock is in the closed (top) position, it seals the chamber from the high pressures created when the cartridge fires and safely transfers the recoil to the action and stock. When the breechblock is in the lowered position, the rear (breech) end of the chamber is exposed to allow ejection or extraction of the fired case and reloading of an unfired cartridge. It is a very strong action; when the breech is closed, the receiver essentially becomes a single piece of steel (as opposed to other actions which rely on lugs to lock the breech). This type of action is used in heavy artillery as well as small arms.[2] An additional advantage is the unobstructed loading path, which imposes no limit on cartridge length; this was significant in the late-19th century era of very long "buffalo" and "express" big-game cartridges.[citation needed]
As well as being used for artillery, falling-block action rifles are still manufactured and used for hunting and target shooting and industrial shotguns (8ga) for shooting clinkers in boilers.[4]
The falling-block action is closely related to that of the Martini–Henry rifle, the Peabody action (similar to, but not identical with, that of the Martini–Henry), the Ballard action, and the Madsen–Rasmussen (uniquely, a repeater), which use a pivoting rather than a sliding block.[citation needed]
