HELP Please: Thread size on FX Bobcat

Does anyone know the thread size on the FX bobcat barell ? I am planning to make an LDC for it so I can screw the shroud directly to the barrell without using an adaptor. 

If any of you who own a bobcat can check the male threading on the muzzle and let me know, so that i get female threads done on end cap and fix it without using an adaptor. Appreciate any help on this. 

Thanks
