Rotating bolt
method of locking used in firearms
Rotating bolt is a method of locking used in firearms. Johann Nicolaus von Dreyse developed the first rotating bolt firearm, the "Dreyse needle gun" in 1836. The Dreyse locked using the bolt handle rather than lugs on the bolt head like the Mauser M 98 or M16. The first rotating bolt rifle with two lugs on the bolt head was the Lebel Model 1886 rifle. The concept has been implemented on most firearms chambered for high powered cartridges since the 20th century.
