It recesses the bore and the rifling deeper into the end of the barrel to protect them against damage from scrapes or bumps. Dents and dings toward the outside diameter won't hurt accuracy. Dents and dings on the inner diameter destroy accuracy. Kind of like bumpers on cars. In a low speed impact you might bend the bumper but at least you won't smash the radiator, and you can still drive it home. Big Grin

In cases where there are muzzle attachments being used, like a compensator or flash suppressor etc., there is no need to recess the crown because the attachment encloses and protects the end of the barrel.
