Well, that is what I wanted to say, its not a one piece mount as in "1 piece mount"
"Rubber bushes help prevent scope damage by reducing the recoil transmitted to the scope." said the text in ramsbottoms link.
Those rubber bushes makes it a dampa mount. In the past I had a couple dampa's in use on heavy recoil springers, to prevent scope damage, (HW80, HW90, Diana 48 etc) but they also made my shots less accurate. (more flyers too)
If your Prosport is a <12ftlbs, there is absolute no reason to use a dampa. Better and more accurate with a one piece mount or double screw Hawke mounts, you
