My nephew had a similar experience when he was still a minor.
His mother agreed to have him placed under observation for a week.

I asked a gun shop owner once if that would disquailfy him.
I was told since it was voluntary and not court ordered, it didn't fit under the term "adjudicated" & he could anwer no to the question.

In the end it didn't matter since my nephew had/has no interest in having a gun.
