  I think I'd start with the lowest temperature one. Excess heat on a bbl is usually not a good thing.

  Force 44 will do the job... Silver solder is a plus but needs lots of heat to flow...

  If you have lead solder it could do the trick. As long as your shooting does not cause excessive barrel heating.

  Let's see Hard moves at 1400? or so Easy moves at 1300? or so. You have to remember you'll have to heat up a good bit of the barrel so if there's any bluing you wanna save it'll be gone. Also if there are any engraving solder'll go in there as well.
  
  I reckon you can alloy your silver to flow at lower temp. I wonder if you can use tooth filling for this application? That amalgam stuff.

  "Vulcans Workshop" on Ebay has quite the assortment of silver solders, and soft solders, too.
  Heat would not be an issue with soft solders-they melt around 400 degrees. I doubt your barrel will get that hot.

  As you must know, you can spot-solder the sight and limit the movement of heat on the barrel. Brownells also sells a product that you can use to "dam up" the area around the sight to prevent heat migration.
  
  However, you may wish to consider the JB Weld, or some other no-heat installation method for installing the sight to prevent marring the barrel. Surface preparation, of course is critical.
  
  By the way, a very good silver-solder flux is a mixture of boric acid and alcohol. You can get 91% isopropyl alcohol (~$2.00)at WalMarts drug dept and in the insecticide dept. at the dollar store (~1.00), buy a small "squirt or puff" bottle (looks like a mustard container) of Roach Proof (or some similar name), a powdered product, which is about 98 or 99 percent boric acid (don't get the stuff mixed with flour and sugar). Mix the boric acid and the alcohol to the saturation point and shake each time before use. Apply with a tootpick or small artist's brush.

  You are right about JB weld. I've used it on many front sights, and have never had a problem.
