👉 The receiver's weapon, often referred to as the barrel or muzzle, is a critical component of firearms that houses and directs the projectile. It typically consists of a metal tube that extends from the barrel to the muzzle, and it is designed to propel the bullet with high velocity and accuracy. The receiver can be equipped with various features, such as rifling (spiral grooves inside the barrel that impart spin to the bullet for better accuracy) and a breech mechanism (for semi-automatic firearms, it allows the bullet to be ejected and loaded for the next shot). Additionally, receivers often include a stock or grip for the user's secure hold and may incorporate safety features to prevent accidental discharge.
