Unobtainable gun Battlefield 2042

It’s really frustrating that the Masterkey underbarrel shotgun was disabled, because the AK5C still requires kills with it to unlock. Right now that makes the AK5C literally unobtainable for players who haven’t already completed the challenge. If content has to be removed for balance or bug reasons, that’s understandable—but there should be an alternative unlock requirement in place so players don’t get locked out of weapons permanently. Can we please get clarification or a fix so the AK5C can still be earned fairly?
