Yes.

I'll reply to whatever I feel like replying to without asking permission.

Oh, the OP may have disappeared but there are others who lurk (as I did for a long time) who will read it.

No one seems to be giving you straight answers, so I will :D For 30cal, I have an SWR Omega that was made in 2001. It is threaded 5/8-24. I use it on a Savage 10/FLP and with a thread adapter, on a Diamondback AR-15 clone. I put full-throttle 223 and 308 through it. Supersonic crack out the ass, but...

I already have 13 suppressors ranging from old Coastal MAC can to Elite Iron Alpha (50BMG)

I saw a newcomer to the suppressor manufacturing ecosystem on GunBroker with a line of suppressors that are cheap enough to be worth trying out.

Curious if anyone has given them a try yet?

I have a Spectre II for my Masterpiece Arms "defender" 5.7x28. Supersonic crack is louder than muzzle report, which means the degree of suppression is as good as it needs to be.

I have the Elite Iron Alpha. I had them make a non-standard thread pattern (1.5"-14) for my LAR. It is plenty quiet. Most recently I put some PMC "bronze" through it. Acts as a very effective muzzle brake as well.
