Trivia

 * A carbine is a cut-down, or shortened, rifle with an attached stock. 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.
