How you are going to use it matters. I have had the Jolene S for 18 months. I have had it on a long range 6.5CM, and 7mmRM on bolt guns and a couple ARs including a 300BO. I have been happy with it and have not had a single issue. I have only used its direct mount. It now sits on my 300BO AR and shooting subsonic ammo. In that configuration it is very quiet to the point that hearing protection is not required. I do have AGBs on all my suppressed ARs including my cans that are low or reduced back pressure. Riflespeed is the cats meow but Griffin's is goo too. The Superlative Arms AGB is good but is a pain to get dialed in unless you have a gap between the handguard and suppressor. You will not be disappointed in the Jolene S.
I highly recommend getting a Trust. I have a traditional trust and it is nice to have all my kids and my wife on it so they can borrow or transport any of my suppressors. A single shot trust is similar. If you buy it as an individual, then only you can use it or at least be near the person shooting it. A trust cost me $100 and only needs to be notarized once you get the paperwork.
