As a weapon mount, a pintle mount is used with machine guns as the mounting hardware that mates the machine gun to a vehicle or tripod. Essentially, the pintle is a bracket with a cylindrical bottom and a cradle for the gun on top; the cylindrical bottom fits into a hole in the tripod while the cradle holds the gun.
