I have no idea, I used the same dimensions as the FUG handle that I've been making, them I just started sketching the forks to where they looked like they blended in with the handle.Looks good to me like the pfs design!!! Is the top part of the pfs 60?
I agree and 2nd this ideaIf you don't build it, I will!
Actually, the right thing to do would be to make 2 simple ones to test drive. In respect to the FUG original designer, send one to Matt and ask his thoughts about it. I'm sure it will be a good shooter and sharing the concept with Matt would be a great way to show your appreciation to the design concept.
