Default jb weld and heat

I would like to install sights on my NEF Pardner shotgun with a fixed mod choke.
I would like to use JB weld for the job.
The spects on JB weld state that it is good up to 650 degrees F.
I might want to remove the sights== damaged sometime in the future

Question : would heating the barrel to ~700 degrees damage the metal??

Yes, and possibly the silver solder holding the barrels together. Temps that hot could affect the temper of the barrels.

If you want to install sights on your shotgun, I'd strongly suggest having a gunsmith to solder them on. If you're dead set on doing it yourself, solder them on or drill & tap for them. It being a NEF Pardner indicates a single barrel or pump. There's NO WAY I'd get a shotgun barrel up to 700 degrees and not expect bad results.

If you had to remove sights put in place with JB Weld...a little kiss from a propane touch and they will come right off----no need to heat up the barrel.

Thanks guys.
I think I will Jb them on and use a micro torch to remove them if the need comes.

By the way I used "airplane model" general purpose glue to stick on the sights to see if they would be acceptable. Much to my great surprise they held through 5 reduced recoil 12 gauge shots and I actually got a zero.. Granted the sights have a large surface area but who would have believed it. I figured I would get only one shot. The Pardner weighs less than 5 pounds and recoil is significant

I must say that I am surprised by your final decision. You get four responses to your question and you pick the one that most matches what you were originally thinking. Which is what all the other responses said was a bad idea. Why even ask a question if you're just going to do whatever you want anyway? Good luck, hope it all works out for you.

Some of my reasoning:
1. one of the sights is plastic and cannot take installation heat BUT if damaged, removal with gentle heat is not a problem.
2. The Pardner I have is a single barrel with no vent rib or solder ribs etc.
3. there is not enough metal thickness to drill/tap or dovetail for sights for the rear sight or scope.
4.There is not a perfect sight to barrel match and the JB weld would help with fitting
5. replies on another forum stated that JB weld can be removed with "slight" heating with a propane torch. This would not require barrel heating to a high degree. Also silver solder melts at a higher temp than JB weld can take.
6.The Pardner is a $100 firearm so any costly modifications with a gunsmith is not worth the expense.. This firearm is a tractor firearm
Finally I thought I would pass on some of my of my findings.
I THANK ALL THAT TOOK THE TIME AND EFFORT TO HELP MY DECISION. And after all It is my decision.

Makes sense, was just curious because you got so many bad responses to the idea. Also, I believe if some of that information was present in the original post you would have received a few different answers. Good luck again though and I really do hope it all works out.

If one asks a vague question- he probably get a vague answer..
I will take the time to be better focused on questions in the future.
Thanks
