[Ulverston]

Hi Chaps,

Hi,
thanks chaps-I would think a supersport-not a Mercury as the set up at the back is totally different...any idea on what parts to order?

Supersport. Many people don't like them, but I enjoyed mine a lot. They kick a bit and tend to kill scopes. Best with open sights I think.

Edit to add: I think coming after the Mercury, people weren't impressed with the looks. I think it's a handsome utilitarian rifle though.
