The '''cocking handle''', also known as '''charging handle''' or '''bolt handle''', is a device on a firearm which, when manipulated, results in the [[bolt (firearms)|bolt]] being pulled to the rear, putting the [[hammer (firearms)|hammer]] or /[[firing pin|striker]] being put into a [[spring (device)|spring]]-loaded ("cocked") "ready and set" position, allowing the operator to open the breech and eject any spent/unwanted [[cartridge (firearms)|cartridge]]/[[shotgun shell|shell]] from the [[chamber (firearms)|chamber]], and then load a new round from the [[magazine (firearms)|magazine]] or [[ammunition belt|belt]] if required. By opening the breech, it also helps the operator to verify that the weapon's chamber is clear of any rounds or other obstructions; to clear a [[firearm malfunction|stoppage]] such as a jam, double-feed, stovepipe or misfire; to facilitate moving the bolt back into battery, acting as a [[forward assist]] (but not necessarily); and to release a bolt locked to the rear by a catching mechanism on a firearm equipped with a "last round bolt hold open" (LRBHO) feature.<ref>{{cite web |url=http://animagraffs.com/how-a-handgun-works-1911-45/ |title=How a Handgun Works: 1911 .45 |author= |date= 14 December 2013|work=AnimaGraffs |publisher= |accessdate=2015-08-06}}</ref>

These devices vary significantly between firearms but may occur in the form of a small protrusion or hook from the side of the [[Bolt action|bolt]], a [[Pump action|pumped slidepump]], or [[leverLever action|lever]] on manual [[repeating firearm]]s.

Cocking handles can be reciprocating or non-reciprocating. The advantage of the former is that it gives the user complete control over the movement of the bolt and bolt carrier. It enables great force to be used to chamber or extract difficult or ruptured cartridges. However, it adds an extra, fast-moving part on the outside of the gun and may limit the way the gun is handled.<ref>{{cite web|url=https://www.reddit.com/r/guns/comments/2ajd6g/what_are_the_advantages_of_a_reciprocating/ |title=What are the advantages of a reciprocating charging handle vs non-reciprocating? |publisher=Reddit Guns|accessdate=2015-08-06}}</ref>
