Part name: Bolt
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.
The bolt itself
is the large metal housing shown below which does
most of the work and is subjected to most of the
stress during operation and firing.
Special Notes: Many men have
had impressions of the bolt face on their thumbs.
Yup, the bolt is the part that slams forward and
creates the famous "M1 Thumb".

These little can openers have been used for years
to open c-rations and other food issued to soldiers
in the field.
