Here ya go, Bret. Studs have been known on occasion to pop off when soldered, even silver brazed, welding isn't probably the best bet. Get a piece of old shotgun barrel, 12ga might work, and cut a piece out to make a saddle that will fit your barrel. Weld the stud upright on the saddle piece, then attach the assembly to your barrel with "silver bearing" solder such as Brownells Hi-Force 44. I prefer the hi-temp variety, melts at something over 600 degrees, still a long way from damaging your barrel steel. Be sure the stud is vertical to the barrel before soldering. You're done and it'll never come off. Hope this helps. GW
