WTB Charger Barrel

Looking for a factory Ruger 10" threaded Charger barrel.

There's a shop which does a lot of custom Ruger stuff and often have take-off barrels. Unfortunately, I can't recall the name. That's where I got the threaded barrel for one of my projects. Maybe one of the other members will come up with a name I recognize.

Another option is to just take a standard 10/22 barrel and cut it down and thread.
