(AR-15) Sale of Prohibited Firearm Out-of-Country

Long story short, I have an AR-15 that's been banned for a few years now since the May 2020 announcement and I'm sick of waiting for the buy back program and have no more use for a rifle I can only practice dry-fire drills on.

From my understanding, selling out of country, i.e. the US, is allowed. Does this seem correct or is it actually possible with all the hoops to jump through? Does anyone have experience with this?
