barrel length
Gun bore dimension
Barrel length is the distance from a firearm's chamber to the muzzle, measured along the bore.
Longer barrels generally increase muzzle velocity and accuracy, while shorter barrels improve maneuverability: The rifle's 20-inch barrel length made it unwieldy in tight spaces.
Barrel length is regulated by law in many jurisdictions, with minimum requirements for rifles and shotguns.
