On factory Colt barrels, there is a small "step" at the end of the threads; the diameter is about as wide as the widest part of the threads themselves. I'm not sure if this is called the shoulder, but it's what I labeled it as in my reference photo.

I want to get a 14.5 barrel cut to 10.3" inches, threaded, and the gas port opened; when you cut/thread the barrel, is this step included?

Perfect; is park no longer available as a finish option (I only see SS blasting under finishes)? Not necessary, just figure if I’m sending it in I’d get everything done at once
