There is not a standard dictionary definition of the phrase "lock stock barrels" as it is a variation of the commonly used idiom "lock, stock, and barrel." However, based on the context, the meaning can be inferred to be similar to the original idiom.
When someone says "lock, stock, and barrel," it typically refers to the entirety or whole of something, leaving no part or aspect untouched. The phrase originates from the parts of a gun: the lock (mechanism for firing), the stock (wooden handle/shotgun or gun butt), and the barrel (the long metal tube through which bullets/projectiles are fired).
In this context, the phrase "lock stock barrels" suggests that these components of a firearm are being emphasized or emphasized even more distinctly than in the traditional "lock, stock, and barrel." The speaker may be emphasizing the total involvement or complete inclusion of every part of some action or process.
For example, if someone were to say, "I sold my truck lock stock barrels," they would be indicating that they sold their vehicle entirely, including all its features, parts, and accessories. This expression indicates a comprehensive transaction that leaves nothing behind.
Keep in mind that since this phrase is not standard, its specific meaning may vary based on the context in which it is used.
