Sealed non violent misdemeanor conviction and the right to bear arms?

With a sealed non violent misdemeanor conviction with no prior arrests or criminal history, it's true that it wouldn't serve as a disqualification to bear arms. This was adjudicated under the youthful offender statute in new York which legally is not a criminal conviction. Any help would be appreciated thank you. It's been 10 years since this happened. The end result was 1.5 years probation and the case is sealed.
