Trivia

 * A carbine is a short barreled rifle or long-barreled stocked pistol. It is very likely than the M6J is a much heavier, longer version of an M6D created to reach this mid-point between rifles and sidearms.
 * Its barrel length is 355mm and it has a detachable shoulder-stock.
 * The M6J has an electroless nickel finish.
