Barrel construction question

[REISINGSTAR 0]

How are the barrel collars attached to the barrel? Are they threaded and screwed on,or is the collar just sweat fit ? I am not building one.Mr. Scott is taking care of that for me,just curious.

The locking collar (breech) is screwed on, the guide collar is press fit and pinned like the front sight and bayonet lug only the pin is larger.
