Garand guts

Lots of fiddly little details on how the guts of a Garand work.  Stuff I didn't know.  Like both sets of teeth on the seer that make the semi-auto trigger possible.  The way the hammer turns the bolt if it has to to fully seat it and won't hit the firing pin home otherwise.  Man on man, I like this kind of detail and info and I am just amazed at what gun designers like Garand and Browning came up with to solve problems, thinking up solutions in their head, then making a thing out of metal that worked.  Complicated enough, but not too complicated.
