I had ADCO cut down my 26" Rem 700P to 20" and thread 5/8x24.
To be honest, I was disappointed, and I have used ADCO multiple times for many different AR builds.
It took me an entire day to thread my flash hider (SE Vortex) on to the barrel. The threads were definitely 5/8x24 but something was out of spec. Email replies from ADCO were to the effect of "Our threads are tight, you may need to just twist harder"
I was literally sweating, using a breaker bar to thread the FH on. It was not the FH either, as I tried two different brands of 5/8x24 muzzle devices.
In the end, it turned out alright. The FH "tapped" the muzzle threads and they are now in spec but I was very disappointed with what I had to go through. I had originally planned on turning this rifle into a suppressed platform, but I think I will buy a new barrel when this wears out as I do not trust the threads for mounting a suppressor.
To be honest, I am not sure I would be able to get the flash hider off the barrel without breaking something.
