The end of the rifle is called the _________ and protects the rifling.

Muzzle
Stock
Crown
Barrel

The correct answer is: Crown

The end of the rifle is referred to as the crown, which is a crucial component as it protects the rifling inside the barrel. The crown is the portion of the barrel's muzzle where the rifling terminates. Properly finishing the crown is vital because it helps ensure that the gases that exit the barrel after firing do so evenly and without disrupting the bullet as it leaves, which is essential for maintaining accuracy. A damaged or poorly finished crown can lead to decreased ballistic performance and precision, making its protective function paramount. The political and engineering considerations surrounding the design and maintenance of the crown emphasize its role in optimizing firearm performance.
