Suppressor shopping. WTF

They're proprietary; and universal- you just gotta try em and find out- Trait "x" doesnt even matter- make sure it can everything from 22lr-50bmg- they work best at matched bore diameter- they sound better when sized up in caliber-

And searching Google is dead. Is there a range within 500 miles of SLC where I can rent/try the top ten sellers? Do I guess from my applying my imagination to numbers I cant relate to? Do I just buy the most expensive per caliber?

How do you pick this garbage apart? Sincerely, Smoothbrain dummy.
