A  '''falling-block action''' (also known as a '''sliding-block action''') is a [[single-shot]] [[firearm action]] in which a solid metal [[breechblock]] slides vertically in grooves cut into the [[breech]] of the weapon and actuated by a lever.

A  '''falling-block action''' (also known as a '''sliding-block action''') is a [[single-shot]] [[firearm action]] in which a solid metal [[breechblock]] slides vertically in grooves cut into the [[breech]] of the rifle and actuated by a lever.  
  
==Description==
+
When in the top position, it is locked and resists the force of [[recoil]] while sealing the chamber. In the lower position, it leaves the chamber open to be loaded by a cartridge from the rear. After loading, the lever returns the block to the top position to lock the breech in place to seal the chamber.

When in the top position, it is locked and resists the force of [[recoil]] while sealing the chamber. In the lower position, it leaves the chamber open to be loaded by a cartridge from the rear. After loading, the lever returns the block to the top position to lock the breech in place to seal the chamber. 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.

Rifles using this action include the M1870 Belgian Comblain, [[Mylonas rifle|M1872 Mylonas]], [[Sharps rifle]], [[Farquharson rifle]], [[Krag-Petersson]], [[Ballard rifle]], 1890 [[Stevens Arms|Stevens]], [[Sharps-Borchardt Model 1878]], [[Winchester Model 1885]], Browning M78 and [[Ruger No. 1]]. Falling-block action military rifles were common in the 19th century. They were replaced for military use by the faster [[bolt action]] rifles, which could reload from a [[magazine]].

Falling-block action rifles are still manufactured and used for hunting and [[target shooting]].
  
As well as artillery, falling-block rifles are still manufactured and used for hunting and [[target shooting]] and [[Firearm (tool)#Shotguns|industrial shotguns]] (8ga) for shooting clinkers in boilers.

It is closely related to the [[Peabody action]], which uses a pivoting rather than a sliding block, used in the [[Martini-Henry]] rifle.

The falling-block action is closely related to the [[Martini-Henry]] rifle, the [[Peabody action]] (similar to, but not identical with, that of the [[Martini-Henry]]), the Ballard action, and the [[Krag-Petersson]] (uniquely, a repeater), which use a pivoting rather than a sliding block.
