A friend asked about the GN quiver on a Hoyt Buffalo. I do not know much about the metal handle bows, but it looked to me like it would fit all those ILF bows like the Morrison and Dryads.

I checked with Bob at Great Northern. Apparently there are some subtle differences between the Buffalo and the ILFs, but he does make a bracket specifically for both of them.
