The flash hider doesn't contact the bullet so it shouldn't hurt accuracy.
the "crown" is kind of like a tiny chamfer around the bore at the muzzle.
i think you're talking about a recessed crown.
to answer your question, a crown is critical to good accuracy. but the only value in recessing it is to keep it from accidentally getting bunged up. so if you're going to attach a FH, you need to pay attention to the crown, but you don't need to recess it

Depends on the Flash hider, Have to remember the gases that are propelling the bullet down the barrel try to pass the bullet when it leaves the barrel. Some flash hiders may have a build of pressure on one side of the bullet, thus having an influence on the bullet. Look for a flash hider that has equal relief. If it is open on the top make sure it has an equal opening on the bottom, same for the sides.

Well, I guess that rules out every M16 & M4 flash hider in military service then.
They all have an open top and a closed bottom to prevent dust signature when firing prone.
BTW: It has no effect one way or the other on accuracy.

I'm under the impression that some types of crown cuts are better than others. AKs seem to come with what I see refereed to as a "factory crowns". Then there are cuts refereed to as "target crowns" that are indeed recessed, but surely there's more benefit to it than just preventing scratches to the tip?
*Edit
After some research, it turns there are no benefits for target crowns other than protection. But wouldn't the flash hider do that job for me anyways? I might be over complicating a simple threading job.

+1, it might influence accuracy if loose, or just by changing the harmonics, but the porting on a FH will not influence the accuracy. FWIW I have a phantom with no bottom port on my M17 and I regularly outshoot folks with post-ban ARs and bolt guns using that rifle.
If you need to get the bbl crowned to begin with you might as well add a recessed crown, otherwise I wouldn't fool with it considering that you plan to add a FH.

I have seen more than one accurate rifle which was ruined as far as accuracy was concerned, by some gun-store commando who decided he needed a flash hider screwed on the end of his rifle. (like the guy down the road who screwed an M60 flash-hider on his 300 Win Mag M-700...***..) But you might get lucky and it might make it better...

Yep, it is a gamble, just depends upon the bbl. Desert Tactical Arms advised me not to put a flash suppressor on my rifle because of harmonics deteriorating the accuracy (not a problem for me, as a 26in. bbl'd .300WM doesn't need it IMO), apparently the brake they offer doesn't have the same effect (I certainly hope not). OTOH the Browning "BOSS" system works in the same manner and allows you to tune the harmonics to the load you use, and reportedly works well (that is if you don't value your ability to hear).

It also allows the gases to push the muzzle down, which does help with target reacquisition.
