Manufacturers and importers may cite Part 272 of Title 15 of the Code of Federal Regulations on foreign commerce and trade (15 CFR 272), which stipulates that ``no person shall manufacture, enter into commerce, ship, transport, or receive any toy, look-alike, or imitation firearm'' without approved markings; these may include an orange tip, orange barrel plug, brightly colored exterior of the whole toy, or transparent construction. However these restrictions do not apply to ``traditional B-B, paint-ball, or pellet-firing air guns that expel a projectile through the force of compressed air, compressed gas, or mechanical spring action, or any combination thereof.'' This language exempts airsoft guns from these requirements, placing them in the same category as bb-guns, pellet, air, and paintball, none of which are conventionally sold or used with an orange tip, and many of which bear as much resemblance to real firearms as airsoft guns do.
 Question: are bb guns required to have an orange tip Context: There have been two postseason no-hitters in MLB history, one by a pitcher from each league. For the AL, on October 8, 1956, Don Larsen of the New York Yankees threw a perfect game in Game 5 of that year's World Series against the Brooklyn Dodgers. The feat had nearly been accomplished nine years earlier by the Yankees' Bill Bevens, who came within one out of a no-hitter (though not a perfect game) against the Brooklyn Dodgers in Game 4 of the 1947 World Series, only to lose the game on a pinch-hit double by Cookie Lavagetto. There have been other one-hitters in the World Series, with the lone hit coming earlier in the game than in Bevens' effort. For the NL, on October 6, 2010, Roy Halladay of the Philadelphia Phillies, in the first postseason appearance of his career, threw the second no-hitter in postseason history, in Game 1 of the Phillies' NLDS against the Cincinnati Reds.
