A Luger No. 1 single-engine four ring block-type rifle. I have .243-caliber of repair barrels. A movement is opened up.

I refer to "the one-shot # ドロッピングブロック action"

The four ring block action is one of the operation of the firearms of the single-fire, and a metal block (chain stopper) slides to the cartridge chamber stern of firearms in a groove cut perpendicularly. This operation is carried out by a lever. I am called the sliding block action.

Four ring block action

When I closed a cartridge chamber, a chain stopper is raised and is put to the position of the top and a movement is in a fixed condition and is opposed to reaction of the discharge. The chain stopper leaves the cartridge chamber at the position where a chain stopper was pulled down once and does it in the opening state that can charge ammunition from the rear. I return a chain stopper to the position of the top that the lever closes a cartridge chamber and fixes it after the loading. When this is a very strong operation method, and a cartridge chamber was closed, in the engine part, it is in parts of the steel which was completely unified. In comparison with other operation methods, these depend on the rag to close a cartridge chamber. The four ring block action is adopted to heavy artillery like firearms.

The following things are included in the rifle using this operation method. M1870 ベルギアン kombu line, M1872 Miro eggplant, Sharp's gun, Farquharson rifle, 1890 Stevens, Sharp's baud Chard M1878, Winchester M1885, Browning automatic pistol M78, I include Luger No. 1 again. The military rifle which adopted a four ring block action was common in the 19th century. Such gun was replaced with the bolt action rifle which had higher discharge speed in using it in the military. The bolt action rifle was able to perform the loading from a magazine.

The rifles of the four ring block action are still produced and are used for hunting and shooting. In addition, it is adopted to the shotgun of 8 gauge diameters made in a maker.

As for the four ring block action, マルティニ Henry gun and a ballad action and the connection using the Peabody action that is not completely same of similar thing are close. In addition, I use a pivot method rather than a sliding block in rare running fire-type クラーグ ペテルッソン.
