Hello everyone i have what seems like a common question but no definite answers to it. I have 2 .22s im wanting to put flash hiders on (for looks) and cant find any info on threading them. I live in the middle of know where with no machine shops near me. Both barrels are measured at .640 inch near the muzzle. Can i thread these for 9/16-24 threads? Whats the max and min diameter for common barrel threads? Please assist thanks.
