I have had my SASS up for sale or trade and someone has an interesting rifle that I might trade for.
I am trying to find info about it. It is a Steyr SSG 69 GAP. It's in a McMillan stock and has a 20" barrel.
I can't find a reference to the GAP SSG 69. There are several models and I am wading through a lot of search results.

Can someone tell me more about this rifle?
What would be an approximate value range so I know what I am discussing in the trade?
