Anyone know what the Brocock Contour S6 threads are?

Anyone happen to know what the threads are on the end of the barrel for an S6? It's not the standard 1/2 UNF

Apparently a milbro hugget moderator will screw directly into it.

Thanks

Oh okay. That certainly can be done... Was just hoping someone might know off hand.

Any idea how to convert from (whatever it is) to something more traditional like the 1/2 UNF ?
You need an adapter from 10mm to 1/2 -20 then you can used any moderator 1/2-20 try Airgun Arizona I have the same gun and they sold me the adapter also try to get the plastic part that cicle the magazine is call the claw they ware ese and you gun would not cycle the mag
