I currently have a 20ga USH with the 1.5-4.5 Bushnell and high rings. (See Preaching to the Choir thread)
The scope seems functional enough but I am not satisfied with it for the following reasons:
1. It seems cloudy under overcast conditions (This may be just this scope)
2. There seems to be a focus problem but this also may just be this one scope
3. This is just me, this gun shoots to distance better than I feel this scope is.
I will be going to a 3x9x50 med duplex (Nikon or Leupold) with Millet rings an do a custom hammer job so that I can lower the ring height.
Just my humble opinion
