I need an ASR mount of some kind to screw into the omega can. For some odd reason, the silencerCo OEM ASR flashhider comes in a 9/16 left hand thread, while the ASR muzzle brake comes in a right hand thread.
That is weird. Are you certain the flash hider isn't offered in both LH and RH threads? It would make more sense if the LH thread version was made specifically for some European rifle. 9/16"-24 LH threads are definitely not any sort of standard in the US, and you'd have a lot of trouble finding other muzzle devices to fit that later down the road.
