1. breechblock

   A breechblock is a part of the firearms that blocks the rear of the chamber while the propellant burns, moving in the receiver along with the barrel for a solid mechanical operation. It essentially closes off the breech end (rear end) of a firearm's barrel and helps facilitate loading and unloading of the ammunition. The method it travels through the receiver determines whether the firearm is a block-action, a slide-action, a bolt-action, a lever-action, a pump-action or a semi-action.

1. Breechblock

   A breechblock is the part of the firearm action that closes the breech of a weapon at the moment of firing. Most modern small firearms use a bolt. Some variations of breechblocks include: ⁕Blowback actions - in which the breech is never locked and is held closed by spring tension alone. ⁕rotating bolt - the bolt rotates to lock into the breech ⁕Tilting breechblock - both self-actuating and manually operated by a lever. ⁕Falling block - ⁕Floating breech ⁕Rolling block - ⁕Hinged breechblock - ⁕Screwed breechblock In artillery the forces are much greater, but similar methods are used. The Welin breech block uses an interrupted screw and is used on weapons with calibres from about 4 inches up to 16 inches or more. Other systems use horizontal or vertical sliding block.
