I had an FN SPR rebarreled to 243 Win. The barrel was made to match the SPR .308 barrel contour that came on it, minus the flutes. I have an SWFA 5-20x50 scope on it with Badger .885 rings and Badger SPR 20 MOA base.

The scope fits but with only a sliver of space between the objective bell and the barrel. Unfortunately, not enough room for scope covers and I really want pop up scope covers on it. Doing some Google searches I found more than a few threads where other FN SPR owners were able to use the same base / rings, with 50mm scopes, and had room for BC scope caps.

Before I go through the hassle of ordering and putting higher rings on.... wanted to see what others experiences have been.
