I have asked this before and also in a thread running at the moment,thought I would start a new thread incase any new eyes might be able to help me.

I have a lovely Sirocco HE Grand Prix, I just love the look of it,but I hardly ever use it
because it is in .22 and I always use .177 for HFT.I would love to use the Sirocco more so contacted Theoben who weren't very helpful and just said there were no .177 barrels available for Sirocco's.
I asked Ben Taylor but he said he doesn't do work on them anymore.

I guess the breech is different on later Evolution models,does anyone know how the barrel is put into the breech as I could get a .177 barrel made I guess. any help would be really greatly appreciated
