The Loctite appealed to me -- seemed like a good and neat one. I have some Loctite 620 for bearing retention and steam crankshaft building. Seems like that would hold permanently -- the threads are pretty fine and it's a big area.
I wouldn't especially be fond of heat myself either. I would guess there is about a 90% chance of the sleeve retainer compound alone being successful, barring any heavy cuts or snags. When I built one of my competition uppers for high power matches I didn't want to drill into the Krieger stainless barrel (stress changes) to use the standard taper pins for attaching the front sight base. I glued it on with 609 sleeve retainer instead. It has not moved one iota from it's fixed position ever since. Still, I would want a couple of pins in a boring head situation serving as a mechanical backup all the same since it has some horsepower behind it.
