I got a conditional discharge on a gun charge can I obtain a gun

... conditional discharge ...

What were the conditions? Discharge, as in dismissal?

What state or country are you in?

Is this your only criminal offense?

A conditional discharge is like an unsupervised probation. I had a conditional discharge when I was charged with a misdemeanor but pled to a violation in NY 15 years ago. The conditions were to pay a $50 fine by XX date and lead a law abiding life. In a year the conditional discharge ended and the record sealed according to NY state 160.55 criminal procedure

That would be "convicted of a felony", under U.S. Federal law. Since we don't know where OP is, we don't know if there may be state law that also applies.

Yes, typo... I forgot the Y. I did add "in the US" because, in this case, if he is a convicted felon, it doesn't matter what state he is in, he is prohibited. But you are correct (of course) as there may be state laws that also apply here. I should have worded my post more clearly I suppose.
