A barrel lug usually protrudes from the bottom of the barrel for attaching it to the stock.
The metal tube for holding the ramrod is called a ferrule.
The lug on the back end of the barrel that fits into a stock is either a "hook" if it's part of a "hooked breech", or it's a "tang" that is attached to the stock by a screw.
A hooked breech eliminates the need to remove a tang screw when removing the barrel. The tang is part of the breech plug that screws into the breech end of the barrel.
