Sako s20 barrel tenon?

[Delicatessen]

I have searched but can’t seem to find any definitive answer; does anyone know if the tikka/sako 85 prefit will work with the s20?

My understanding is that the 85's tenon thread is a standard imperial 1"-16 while the s20 is a metric M27-1.5.

Do you have a worn out S20 barrel? I'm looking to rebarrel an old FN49 battle rifle, and it happens to have the same thread.

Thanks!
