Need a better shot of that front tube to see the actual detail. Over the years I have seen a lot of mismatched Stith parts.
Is that scope tube really inserted all the way in the front tube? It just doesn't look right.
I will take another shot of the mount later today. I loosened the rear ring and tried to push the scope forward for a little more eye relief and it would not go any further forward. After looking at the scope a little closer I would not have been able to get much more anyway as the rear of the scope was already pretty close to the rear of the base anyway.
