No it is not normal. That said the only way to fix it is to remove the current finish and redo the the blueing process again on metal taken back to the white.

Contact your gunsmith and determine if he will accept the gun back and refinish it again or simply refund the money and you send it to a gunsmith with the proper process for the M21
