HOW A MAUSER KARABINER 98K WORKS

The Karabiner 98 Kurz is a bolt-action rifle chambered for the 7.92×57mm Mauser cartridge that was adopted on 21 June 1935 as the standard service rifle by the German Wehrmacht. It was one of the final developments in the long line of Mauser military rifles. Although supplemented by semi- and fully automatic rifles during World War II, it remained the primary German service rifle until the end of the war in 1945.

The Karabiner 98k is a controlled-feed bolt-action rifle based on the Mauser M 98 system. Its internal magazine can be loaded with five 7.92×57mm Mauser cartridges from a stripper clip or one-by-one. The straight bolt handle found on the Gewehr 98 bolt was replaced by a turned-down bolt handle on the Karabiner 98k. This change made it easier to rapidly operate the bolt, reduced the amount the handle projected beyond the receiver, and enabled mounting of aiming optics directly above the receiver. Each rifle was furnished with a short length of cleaning rod, fitted through the bayonet stud. The joined rods from 3 rifles provided one full-length cleaning rod.

This rifle has a "turn-bolt" or "turn-pull" design, which involves the shooter doing an upward "turn" movement of the handle to unlock the bolt from the breech and cock the firing pin, followed by a rearward "pull" to open the breech, extract the spent cartridge case, then reverse the whole process to chamber the next cartridge and relock the breech. It features "Cock On Opening", meaning the upward rotation of the bolt when the rifle is opened cocks the firing pin (there's a Cam mechanism pushing the Cocking Piece of the Firing Pin backward)
