Gun barrel
From Biocrawler, the free encyclopedia.
(Redirected from Barrel (firearms))
The barrel of a gun or other firearm is the tube, usually metal, through which a controlled explosion is released in order to propel a projectile out of the end at great speed.
The first guns were made in a time where metallurgy was not quite what it is today, so the pipe needed to be braced periodically along its length, producing an appearance somewhat reminiscent of a barrel.
