What is the primary material that composes the part of an inline muzzleloader known as the stock?

The stock of an inline muzzleloader is primarily composed of wood due to its traditional properties and advantages. Wood has been used for centuries in firearm construction because it provides a combination of durability, strength, and aesthetic appeal. It can effectively absorb recoil and is often favored for its natural feel and ability to be shaped comfortably to fit the shooter's shoulder.

While other materials such as metal, plastic, and carbon fiber are indeed used in firearm construction, especially in modern designs, wood remains the most common choice for the stock, especially in traditional muzzleloading firearms. Each of these alternative materials may serve specific functions or appeal in different firearm applications, but wood is particularly valued in the context of inline muzzleloaders for its balance of functionality and craftsmanship.
