context_page_description: In firearms terminology, an action is the functional mechanism of a breech-loading weapon that handles the ammunition, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot weapons with a closed off breech and the ammunition is manually loaded through the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock.
  Actions can be categorized in several ways, including single action versus double action, break action versus bolt action, and others. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of 2.8 in or smaller. The long action rifle can accommodate a cartridge of 3.34 in, and the magnum action rifle can accommodate cartridges of 3.6 in, or longer in length.

  The Orvill Robinson Model 2 rifle: Orvill Robinson, a New York-based firearms designer, developed two rifles. His first, patented in 1870 and commonly referred to by collectors as the "Model 1" though it has no official designation, was a precursor to straight-pull bolt actions like the Mannlicher M1886. The second rifle designed by Robinson, patented in 1872, was very different, employing a double hinged action that folded upward from the receiver to remove the spent casing and back down and forward to chamber a new round. Though hammer-fired, it is recognizable as a manually actuated ancestor of the toggle action found in firearms such as the Luger Parabellum 1908 pistol or Pedersen Rifle.
  Krag-Petersson Rifle Though frequently classified as only single-shot firearms, one tilting block rifle usually falls under the category of repeating firearms. The user, upon ejecting a round from the chamber, would load a round from the underbarrel magazine onto the loading surface of the tilting block, then raise it to the mouth of the chamber where the user could then easily push it forward into the chamber. Though this would not meet most standards of "repeating" for most modern users, the classification has been in use historically.
  Remington-Rider Magazine Pistol has a manually-actuated rolling block action to pull a cartridge from a tubular magazine set below the barrel and simultaneously cock the weapon. The block was rolled back into battery, loading the cartridge into the chamber, by spring pressure while the hammer remained in the cocked position.
