Are you sure about that? I thought the YS 61 is the same size as a 91? The YS 60 yes but older 61?

Yes, it fits just fine. I ran one in mine for a while.

if it is the same size as a .91 then I don't know....

Rodney, are you sure you ran a .61, and not a .60?

the ys 60 is 17.5mm x 44mm mounting pattern

the ys 61 is 25mm x 52mm

I miss read the original post I did think you meant a 60. I don't think the 61 will fit without modifications.
