"Percussion cap long guns and muzzle-loading black powder handguns made after 1898 are not classified as antiques even if they are copies of an earlier antique model. Newer percussion cap long guns are classified as non-restricted firearms; newer handguns, including matchlock, wheel lock and flintlock handguns made after 1898, are classified as restricted if their barrel length is over 105 mm (about 4 inches), or prohibited if their barrel length is 105 mm or less."
