Part name: Bolt Group
Part Function: The bolt and its internal
parts are responsible for stripping a round from
the clip, chambering it, indenting the cartridge's
primer, extracting the spent shell casing from the
chamber, and ejecting the casing from the weapon.
When all of these parts are
assembled as shown below they are known as the Bolt
Assembly or Bolt Group.
Special Notes: Many men have
had impressions of the bolt face on their thumbs.
Yup, this is the part that slams forward and creates
the famous "M1 Thumb".
Other items of interest in this
photograph: Wartime Pennies. In
1943 the US Government was running short of the
copper used to mint the traditional penny and so
the mints began to produce steel 1 cent pieces.
The pennies retained the traditional wheatback /
Lincoln design but the silver metal turned people
off. The coin was so unpopular that the government
quit minting steel cents the next year (1944).
