I was thinking Krazy Glue is thin enough that it would penetrate everywhere. As long as it stays put I don't have to worry about removing it. Not sure but I think acetone would remove Krazy Glue. If I could get the pins out and the flash hider off I would try the epoxy but I don't think it's loose enough to get off easily and I don't want to damage the bayonet lug or anything. I found Peter Laidler's reply to a loose LE #5 flash hider Quote....Ok............, ok, ok..... This is how WE did it. There may be other methods but this is the one we used gained from long hard won experience. Remove the two morse taper cross pins. Sometimes they'll tap out quite easily. Others will need a bit of coaxing with a lump hammer and a short stubby drift to start them (then they'll drop out.....). Others will need pressing out on a press. If you really do butcher the pins then you'll need to drill them to start. We had a small drilling template.
Once the pins are out you might find one that will just tap off but be warned................. Any more than a gently tap will damage/bend the bayonet standard and you'll never fit a bayonet if you need to refit the flash eliminator. Or you might damage the foresight protector ears. It's better to press it off right from the word go. But if you want to use heat or just a big hammer, that's up to you........
Put the rifle upright into the press, barrel between two vee blocks just as though you were pressing out a set of wheel bearings. Then, we had a short dumpy piece of hard nickel rod that was an exact fit into the core of the flash eliminator with a centre spigot that would 'centre' into the bore of the barrel. The outer diameter would just sit onto the flat of the muzzle of course. Now operate the press lever and the barrel/action will be pressed out of the flash eliminator with no damage of any sort.
I don’t remember any solder or tinning of any sort although there might have been for a loose one……… but if it were loose, we’d find and fit one that wasn’t!
Refit and align the flash eliminator as you would for fitting a barrel. Ream out the taper pin holes to accept the new taper pins, refit the pins and tap them tight. ........... After reading that I think I'll likely try Krazy Glue first. Jack
