The part of the action that locks the mechanism during discharge. In bolt action weapons it is the cylindrical or oblong block of steel so designed that it may be pushed forward and locked to seal the breech for firing, then withdrawn to permit ejection of the fired case and loading of another cartridge.
a sliding bar in a breech-loading firearm that ejects an empty cartridge and replaces it and closes the breech
the part of a lock that is engaged or withdrawn with a key
the act of moving with great haste; "he made a dash for the door"
secure or lock with a bolt; "bolt the door"
Solid shot for rifled cannon, typically a cylinder with a pointed nose. For illustrations and more explanation, see the Ammunition page.
The brass or steel section of a lock that is operated by rotating the key or knob and extends from the lock case into a cavity in a frame, preventing the door or window from being opened.
The part of the rifle which is similar to a door bolt. The bolt contains the cartridge and bullets. After the rifle is shot, it will push out the used casing.
The projectable member of a lock or latch mechanism that engages the door frame and the strike. (See deadbolt and latchbolt.)
The bolt is usually found in rifles and is the part of the rifle's action that moves in and out of the breech and serves as the rear of the firing chamber. In lever action rifles, the bolt is moved out of the chamber through the action of the lever. It removes the spent cartridge from the firing chamber and discards it. It also picks up a new cartridge from the magazine and pushes it into the breech. The bolt is locked into place and helps retain the cartridge and combustion pressure.
A device usually made from brass or steel used to secure a door or gate to its frame.
The part of a lock which, when actuated, is projected (or "thrown") from the lock into a retaining member, such as a strike plate, to prevent a door or window from moving or opening. See also dead bolt, flush bolt, and latch.
The bolt is the component that actually does the locking. When the key is turned the bolt shoots out of the lock and secures the door to the frame. In box and chest locks the bolt is hidden and prevents the link from coming out of the lock when locked.
The piece of metal that protrudes and secures or closes a door.
The part of the lock which provides the engagement in the keep by protruding from the lock case.
The locking and cartridge-supporting mechanism of a firearm that operates in line with the axis of the bore. It contains the firing pin, firing pin spring, extractor(s) and sometimes the ejector.
The handle that cocks / charges / reloads a gun The bolt is present on most rifles and SMGs, both real and airsoft. When manipulated, it allows the user to pull back the slide hidden inside a gun and load a fresh bullet or BB. A bolt is unnecessary on guns where the slide is readily accessible (such as semi-automatic pistols). NOTE: While AEGs have a bolt, the mechanism of the AEG at this time means that the bolt has no function. It is entirely cosmetic in all but a rare few AEGs.
A steel rod-like assembly similar in design and operation to a normal door bolt, which moves back and forth in the action when operated by the shooter's hand. It seals the cartridge in the chamber during firing and extracts it afterwards, OR, In automatic and semi-automatic repeating guns, it loads the rounds from the magazine and unloads the fired cases, it may only have a passing resemblance to a door bolt and may not turn to lock.
A mechanical device for blocking the breech and holding the cartridge in the chamber during firing to prevent rearward escape of gases.
A bolt is a mechanical part of a firearm that blocks the rear of the chamber while the powder burns.
