IMHO it all depends on what accuracy you are after and at what distances to a bit.
Answer that and you will get your answer.
Being you have a factory barrel on there, I"d be happy to an extent with that.
A good tube should cut that in half more or less.
Truing will help and I would suspect a custom action might help even more.
But what are you after in the end?
Being that I've owned ARs that are far from custom that run around .3/.4 moa out to 600 yards, just because a good true barrel was put on, we really need to know what you are after.
Not what others want, what you want, regardless of if you need it in any of our opinions or not.
