Pawn Stars Question

I watched new Pawn Stars last night for the first time  in months.
Corey and Chumlee looked like crap, the Old Man was no where to be seen and the story lines were basically the same.
But I noticed this....
Chumlee was convicted of a felony conviction of illegal possession of a gun and a minor firearm charge last ýear.
In the last episode, Chumlee fired a 7 barrel shot gun at the gun range.
According to Nevada law, if you are convicted of a felony you may not possess a firearm.
I suppose the legal dept. of Pawn Stars checked it out.
But it certainly looks like Chumlee violated the conditions of his probation.
