An extractor also performs the function of an ejector in revolvers. When the striking force applied to the ejector rod is hard and fast enough, the extractor will typically eject the empty case(s) from the cylinder. Some break-action shotguns are also designed to eject empty shells completely out of the chamber when the barrel is opened.
A zamburak consisted of a soldier on a camel with a mounted swivel gun (a small falconet) hinged on a metal fork-rest protruding from the camel's saddle. To fire it, the camel was put on its knees. The name is derived from the Persian word for wasp zambur (زنبور), possibly in reference to the sound earlier camel-mounted crossbows made. The ...
By creating a pressure differential in the barrel after the shell leaves, the bore evacuator causes most of the propellant gases and combustion residues to exit via the muzzle. Thus, when the breech opens for reloading, those gases and residues do not escape into the crew compartment and pose a hazard to the gun crew. [1]

A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1]
Close-up of an IOF 32 break-action revolver. The first break-action revolver was patented in France and Britain at the end of December in 1858 by Devisme. [1] A substantial hinge pin joins the two parts of the rifle or shotgun; the stock with its firing mechanism and the fore-piece and barrel, which hold the round to be fired.
Mason began his career as an apprentice patternmaker, eventually working in the arms industry for Remington Arms.While at Remington, on November 21, 1865, he received U.S. patent 51,117, for a swing-out cylinder for easy loading and the star ejector mechanism to eject spent cartridge cases, a design used in 1896 by S&W for the .38 Hand Ejector (M&P and S&W Model 10).
