I have a BSA Monarch 2nd pattern in .270 Win in it's original state i.e. not screw cut.
I'm considering having a moderator fitted in the near future. My question is what size thread should I go for? I realise that there is no standard size but that I may change the rifle in future. With this in mind, are some threads more common than others? Can adapters be purchased to allow the same mod to be used on different rifles (of the same calibre?). I don't want to spend £300 on a new mod, only to discover it won't fit on any future purchase.
Many thanks for any help
