Hi all,

I read Coddy's comment on the Supersport history thread about him fitting a Theoben Sirocco barrel to a Supersport, not sure if he meant just the barrel or the whole breech block as well? I've emailed him because he's been banned but it's bounced back, now I just happen to have a spare Theoben breech block and barrel here and it is remarkably close in a lot of ways to the size and fixing points to the BSA set up, the only thing different is the width of the breech block which is 2mm thicker, so obviously won't fit in the Supersports breech fork, looking at it, I don't think milling a mm of each side could be done as I'd say the barrel wouldn't have enough metal left to hold it, so I would say the breech forks would need to be milled, is that possible to do?

Would it be a viable conversion?

Your thoughts please gents.

Cheers
