Does anyone have experience of using a rivet gun to replace a loose bottle boss on an alloy frame?
Do you mean a rivnut/nutsert setting tool?
If so I have done a few on both aluminium and steel frames.
Use aluminium nutserts as they are easier to "pull up" compared to steel.
Biggest problem may be getting the old out out without enlarging the hole too much, the drilling size is 7.1mm for an M5 nutsert.

Does anyone have experience of using a rivet gun to replace a loose bottle boss on an alloy frame? I've done the M5 bolt trick a few times to tighten it up but this time it seems to not work. Otherwise is epoxy a worthwhile alternative option?
