Silver solder 14.5" AR? Your pics/experience!

Has anyone here done this? I've read about it on Arfcom, and am considering doing it. Much easier and cleaner than pin/weld it looks like.

Any pics?

Well - the problem is that you're heating up the barrel steel (if you're doing it right) and that's a delicate process to do without damaging the barrel.

Mike at Oklahoma Police Supply did a Phantom 5-port on mine.

Silver solder melting temp should be far below re-tempering the barrel.

Silver solder will melt at around 1250-1500 deg F (depending on alloy) and will typically flow at 10-50 degrees above melting temp. Depending on your barrel temper, this may or may not effect your barrel. You will definitely have to refinish your barrel and flash hider.

Actually, its not that far below the temp that actually affects the barrel - and if you're doing it at home, you've got to know where that point is and how far you cannot go.

I just know that the guys on arfcom have used the stuff from brownells and other sites that have a melt temp of 1150* and haven't had a problem with anything. Not even hurt the phosphate finish.

We'll see I guess. I think I'll try it...

Call Brownell's tech line, and they'll tell you exactly what you need. Tempilaq is the stuff you're talking about, when it runs, the steel is "just right". Having some Stop-Heat on the barrel isn't a bad idea...
