Part name: Barrel
Part Function: The Barrel is a tube of metal
with spiral cut channels on the inside. The high
point of these channels are called lands the low
points are called grooves. This set of lands and
groves are called rifling inside a barrel.
The barrel stabilizes the fired
bullet before it leaves the rifle by imparting a
spin on it as the bullet passes down the barrel.
M1 Garand barrels have a tiny
hole drilled through them near the muzzle. (The
forward tip of the barrel.) This hole vents a bit
of the gas produced by the combustion of the gunpowder
into the Gas Cylinder so as to operate the semiautomatic
mechanism of the rifle.
The barrel on an M1 also has
an integral 'chamber' machined into it which holds
the cartridge before it is fired.
