lock, stock, and barrel
colloquial phrase

- including all, or every part of something

ORIGIN

Picture an old-fashioned musket - the kind used in the American revolution.

The LOCK is the firing mechanism. That’s the part of the gun where a match or a spark was used to ignite gunpowder.

The STOCK is the thick wooden end of a gun.

The BARREL is the long, cylindrical part of the gun, the tube down which a bullet travels.

The first known use of this term in a metaphoric sense is in a letter written by Sir Walter Scott in 1817. In describing a broken fountain he wanted to put in his garden, he wrote that “Like the Highlandman’s gun, she wants stock, lock, and barrel, to put her into repair.” In other words, nearly every part of it needed to be fixed.

A variation of this phrase that’s now obsolete is “horse, foot, and artillery.” These items referred to the components of an army. The “horse” is the cavalry; the “foot” is the soldiers; and the “artillery” is the weaponry.
