Has anyone ever used loc-tite on a barrel nut to basically create a shouldered rifle barrel? I was just trying to think of a way to get consistent headspace when swapping barrels when I thought of this.

My thought is, get a new nut for each barrel. Headspace it like normal, but once you have it where you want it just put some medium strength loc-tite on the nut to hold it's position. Now all you need to do is tighten doen the barrel every time, and you 're good. I don't know that this is any better or more accurate than just using witness marks but it sounded like a decent idea. Any thoughts?
