They are expensive but worth it! Real question is does a local CO or officer even check the paperwork ? I’ve never been stopped with mine but always wondered how it would go .
I’m on my 5th suppressor purchase through Silencer Shop. The process has been reliable and straightforward. I’ve used the Single Shot trust offered by Silencer Shop as it meets my needs.
I always carry copies of my paperwork when at the range or hunting so I could produce it if asked for it. That said, I’ve chatted with COs in a number of states while hunting suppressed and none of them have even batted an eye about the can on the end of my rifle. I even had one CO in MT that was interested in the 22 Creedmoor I was carrying while hunting antelope to the point where he asked to shoulder it and work the action. I dropped the mag and let him have at it. He never once said anything about wanting to see paperwork.
And yes, wait times seem to no longer be the issue they were in the past. I waited over a year for my first one. My last one came back in about a month and I hear wait times continue to decrease from there.
