Wetherby .308 has a spigot?

[Rabbit foot]

Hi all I was given the above by a friend it is threaded with 14/1 I'm thinking a mod would be a good idea but it has a spigot I believe, how Do I go about buying a mod for a barrel with a spigot? Does it need to be different to a standard mod?
Looking for a s/h mod local to north Wales potentially
Cheers

IMO spigot is the correct way of fitting an over barrel moderator will be some about second hand try a wanted ad or give Jackson rifles a call or Ed @ Edinburgh rifles

You can check whether your thread conforms to spigot thread or regular thread (called Sako thread in the PDF although similar fit has been used long before AU started calling is Sako thread):

Most manufacturers offer also spigot thread here in Scandinavia / Finland. Traditionally spigot required 0.5mm shoulder per side and regular thread 1mm per side. AU has split the difference and AFAIK they've been trying to outphase the spigot thread.
