Not sure if this is the right place or not but I've got a Bushmaster ACR and I'm interested in having it SBR registered. Does anyone know of a gunsmith who can chop down, recrown and thread a barrel properly. I really need the barrel before I do the paperwork so that I can put the dimensions down. If not someone who can cut it down, someone who can manufacture an SBR barrel.

There was a thread a while back where a member used an AR barrel and barrel nut. Not sure if it was sbr or not but that is one route you could go instead of cutting your barrel. If I remember correctly he said it improved his accuracy getting rid of the quick change barrel system.
I've used Marvin Pitts (Nefarious Arms) to chop, ream the gas port, re thread and re crown my SCAR SBR project. He does great work!

Unless you get a factory 10.5" barrel & gas system to swap in, you'll be limited to about a 13.5" bbl due to the mid-length gas system of the factory 16" bbl. You won't be ditching the quick change system either way & you'll have to re-use some of it anyway, if you don't get a whole other assembly from Bushmaster. Just get a quality aftermarket barrel with a mid-length gas system that's chrome lined & have it fitted by a competent gunsmith(the spacing is different on the pins that hold the gas block on). You'll also have to turn down a small recess behind the gas block for the push rod/piston guide to bolt to.
