I've got use of a Bobcat Mk I, .22 for a while. It's quiet but I'm wanting to "mouse fart" it. Looked at FX's MK I diagrams but don't see thread sizes for an adapter. Gonna try my Ronin on it. Here's a pic. 
Anybody using a Donny on a Bobcat MK I?

you need one of these, Gerry. One longer, one short. Longer one is meant to clear the air tube with a gun whose barrel shroud finishes shorter than the air tube, like the MK2 wildcats with the 600mm barrel. Looking at you pics, you just need the short version. M20 x 1.25 female thread to 1/2-20 male threads

I owned a MK1 a long while back and I recollect that at one point, I removed the OEM shroud. I believe the threads on the barrel that mated to the shroud were 1/2 X 20, and I was able to direct thread a Donny FL. It was amazingly quiet.
