Re: SAS Arbiter Ti 7.62 Suppressor Thread Guide
My best advice is to be patient and wait until you have the suppressor. Then send the suppressor and rifle to your 'smith for proper threading. Sucks to wait; I know. But that is the BEST way to ensure best fit.
I've seen LOTS of suppressors from just about every company you can imagine and threads are not always to that company's published spec. LOTS of variance.
Your call though.
