The muzzle of the barrel is specially machined to protect the rifling, therefore preserving and protecting accuracy. This is a critical feature on any barrel. If riflings are damaged in any way, especially at the muzzle, accuracy suffers and it is often difficult to determine the cause.
Browning X-Bolt and A-Bolt rifles have a short 60° bolt lift. Many competitors' rifles incorporate a 90° bolt lift that is not only slower and cumbersome but places the bolt near or on the rifle's scope, making the bolt more difficult to operate.
