In terms of the best product from Loctite for retention of cylindrical parts - 620 is good, but is 660 better? It is significantly higher viscosity, and has about twice the gap filling ability as well. For those of you who have a really loose fit, it is actually designed for retaining shims too.
I have used it, but I also haven't done the extensive testing others have here. Everything I assembled with it shot very well. And then again I have assembled uppers with only grease and they shot well too. Probably placebo effect.
