v. to cut or manufacture spiraling grooves - most often times inside the barrel of a gun or small arm

n. any small arm that features rifling inside its barrel

Note: Science fiction often mistakenly refers to some portable LASER weapons as "rifles" or "laser rifles". Unless the weapon features rifling (which is unlikely and useless to a laser), then these terms are incorrect.
