I talked with bruz about most of this a couple or three days ago and am pretty sure I can answer most of your questions.
It's a factory barrel that was chambered and had the snakeskin finish applied by RW Hart and the muzzle brake
was put on at the same time too.
He told me that there were less than a hundred rounds through it but I can't for the life of me remember. I think it was 54 or something like that but am almost sure it was less than a hundred.
Note: You can see the Remington Stamped letters on the barrel in the picture so it's for sure a Remington blank/barrel.
I never did ask him if the brake is removeable but it sure doesn't look like it is.
I also don't know the barrel length.
