When we talk about "stock and barrel", we're usually referring to the entirety of something - all of its parts and pieces. But what are some other phrases we could use to convey the same idea? "The whole kit and caboodle" is one option, suggesting that everything included in the package. "Lock, stock, and barrel" is a similar phrase that includes the additional idea of being completely committed to something. "The whole enchilada" is a more casual phrase that conveys the same idea. No matter which phrase you choose, the underlying message is clear - we're talking about everything and anything that's part of a larger whole.
