If you were going to start the NFA game and build a suppressor system for 556 to 338, what would you do? I have AR15s in 556 and 300 blk. AR10 in 308 and hopefully 338/8.6 Creed someday, a 6 Creed and hopefully a 338 mag of some sort someday. I like the YHM Turbo K with either a Key Mo or Plan A mount. Is there another company out there that makes them all? I like the Sig lineup but their mounts are not backwards compatible which is a drag.
