The Black Powder Rifle is a long, muzzle-loading firearm with a distinctive wooden stock and a dark, aged metal barrel. The stock features intricate carvings and a slightly worn finish, showcasing its historical use. The metal components are heavily weathered, with visible rust and pitting, while the barrel is smooth and slightly tapered towards the muzzle, ending in a flared muzzle brake. The rifle's overall design is symmetrical and elongated, with a simple yet functional trigger mechanism and a prominent hammer.
