The bolt is a mechanism that is operated by hand to extract a fired cartridge, move a fresh round into the chamber and reset the firing pin, readying the weapon to fire again. The bolt closes the breech end of the barrel and contains the [[firing pin]]. The bolt is held in place with a lever that fits into a notch. Moving this lever out of the notch will release the restraint on the bolt, allowing it to be drawn back. An [[extractor (firearms)|extractor]] removes the spent cartridge, which is then ejected through the lever slot. A spring at the bottom of the [[magazine (firearms)|magazine]] pushes up the reserve rounds, positioning the topmost between the bolt and the chamber at the base of the [[gun barrel|barrel]]. Pushing the bolt lever forward chambers this round and pushing the lever into the notch locks the bolt and enables the [[trigger (firearms)|trigger]] mechanism. The complete cycle action also resets the firing pin. The [[Mauser]] rifle of the late 19th and early 20th centuries is the most famous of the bolt-action types,{{citation needed|date=August 2013}} with most similar weapons derived from this pioneering design, such as the [[M1903 Springfield]] and the [[Karabiner 98]] Kurz rifle (abbreviated often as Kar98k or simply K98). The Russian [[Mosin–Nagant]] rifle, the British [[Lee–Enfield]], and the Norwegian [[Krag–Jørgensen]] are examples of bolt-action designs.
