I put in my request for a suppressor tax stamp the first week in february and my check was electronically cashed the next week. 4 months left or so. I got an AAC Eco before they were discontinued.
I'm saving for a rifle suppressor now. I was thinking of a YHM 7.62 stainless QD for a 5.56 AR and a future 300 Blk and .308 bolt gun. While I wait 6 more months I can buy the rifles!
