I have heard good things about the Bowers Vers 50. I don't know how well it would work stepping down to 308 though. Its an awfully big bore to suppress. I see that this post was from February though, did you end up ordering one yet? I would like to know because I have a 50 I was thinking about suppressing but I put a boat of a muzzle break on it instead (threaded).
good deal! Id like to know how you like it when you get the form 4 back. BTW I just talked to the ATF and they are finishing up march applications now. They will start on April soon
