I think that's what happened or it wasn't seated all the way and he righted the lock ring but it didn't lockOk
Explain
My Surefire suppressor has an incredibly elegant, refined and secure mounting mechanism.
Did someone just forget to turn the locking ring on the rear of the can????
No. The owner paid themWas the dive search just "professional courtesy"?
Yes, we would have notified ATFLegal question.....
Had the can NOT been recovered form it's swim would the owner be wise and/or obligated to notify the NFA authorities?
