I would like to make a mandrel for trueing/facing AR-15 upper receivers (where the barrel extension mates with the upper receiver).
Questions:
1. Has anyone made one of these?
2. What diameter did you turn it to?
3. Did you taper it at all?
4. How did you keep the receiver from spinning or moving laterally? (if not tapered)
Also- how much material do you take off when doing this procedure? Did you turn between centers?
Thanks,
Gavin
