I have an almost new CGS Hekate 338 in 18m-1.5 thread pitch. I have 5 rounds through it that I used for subs on an 8.6blk bolt gun. I am moving on from that caliber. I will form 3 it and send via my FFL. It is super quiet and nice but I just don’t need it and could use the extra funds. I also have a Burn Proof Suppressor cover that I will include. $1200 shipped.
