How would someone rethread a Draco barrel with a different thread pitch when the draco is already threaded with 14x1 thread pitch.  Also does anyone happen to know off hand what barrel OD you need to have for 5/8 -24?

OD needs to be 5/8", give or take a .001".  You can't re-/over-cut, you'll need an adaptor.  These guys might be able to help you: Tornado Technologies

Thx for the info but looks like they didnt have anything for it.  Also wouldnt that mean the thread have to be concentric to the bore even if i add an adapter?  Because if they weren't wouldnt that throw off the other threads?

Tornado does not list such an adaptor- that doesn't mean they don't have one, or can't make one.  If they have a couple of protos in a box, you might get a good deal; if you needed to have one made, I'm guessing $75-90.

You didn't mention your threading being non-concentric...?  What makes you think so?

IMO, you're going waaayy too far on a Draco.  There is the $100 PWS brake/FH, on down to the $25 Phantom copy available in 14x1mm, both are excellent, with other options of varying effectiveness in betwen.

I'm not doing it just because I have a draco.  I planned on getting an AAC 7.62 sd can for four of my aks.  I was going to thread them all and put their quick detach muzzle brakes on them so I can just swap it.

Gotch.  I wouldn't have any clue, but have you checked with AAC on the pressure from the Draco?  I'm sure you'll get adequate backpressure, I'd just be concerned with the pressure in the can.
