WTK: Muzzele Thread Size for my Swiss SG 510 T AMT

[md66948]

My Swiss SG 510 T AMT (American Match Target) was imported without a Brake/FH. Does
anyone have any idea what pitch and size the threads maybe on this barrel? I was planning to go to HD and buy some nuts in several different metric sizes and see what one threads onto the barrel.

I got my answer from Kontaktaufnahme in Switzerland.

"The muzzle thread should be an M15x1. The muzzle brake of the FN-49 should work and you see that sometimes on these rifles."
