Don,
That information certainly is helpful to those that may have been considering a B. Rizz gun. I had seen some of their guns and thought of them for some of my hunting uses, but that's not on the table now.

Given that this condition may exceed the ability of EHG to eliminate completely, I'd would think there would be some visual cues. If you lay the barrel on its side and sight along the upper barrel, does it noticably 'swoop' up?
