Threads size & pitch

[SniPeralez]

I have the FX Wildcat 1st Gen. in .25 all original as far as I know. I want to add a silencer, so I ordered this adapter part, but the thread on the shroud is coarse compared to the adapter, what size do I need?

Thanks

Threads size & pitch: M20 X 1:

So far all I've just seen is the same size as this one. M20 X 1, but I'll look again. Thanks
