SumToy Mount

Looking for some info in Williams mount for a Fast Fire.  Wanting to mount it on my Sa459 20ga.  The gun has 3 holes drilled and tapped for a factory rail. Wondering if anyone can give me the length between the mounting holes.

Thank you.

we have one for that set up.     Just let us know when you call in that it is the three hole set up.   She knows to ask about the Browning but not this one. 

Thanks
William
