Bolt Action

[bohlt-ak-shuh n]

  • An action type, most frequently used on rifles, perfected by Peter Paul Mauser in 1898, whereby a cylindrical shaft, controlled by an attached lever, manually feeds a cartridge into the chamber, rotates a partial revolution engaging locking lugs in complementary recesses in the front receiver ring, allows firing by the fall of an internal spring-loaded pin, opening, extraction, re-cocking and ejection with the same lever in preparation for the next shot.
  • A type of firearm, almost always a rifle, in which an empty shell casing is removed from the firing chamber by the turning and retraction of a metal cylinder shaped mechanism called a bolt. A new, un-fired, cartridge is inserted and secured into the chamber by reversing the action of the bolt.
