I think you have to buy the Tri-Lug separate. But I do suggest not going budget on a suppressor. The YHM cans kind of suck, and so do SilencerCo cans. The SiCo Octanes were having severe QC issues several years ago, with baffles and end caps not being welded on straight, off-center machined baffle stacks and end caps causing strikes, etc... It was a real shitshow. I would strongly suggest not wasting your money on anything SilencerCo or YHM. The YHM cans are well built, they're just not very quiet. And the whole point of a suppressor is to suppress...Blast, flash, and sound signature. If it doesn't do any/all of those things very well, then, IMO, it's not worth the $200 tax stamp.
My opinion is get the Wolfman or Lithium.
Wipes work, but are kind of gimmicky, only because they don't last but a few shots, and you also cannot shoot expanding or HP ammo through them, or it will expand as it pushes through the wipe, causing some "interesting" things to happen. This is why I suggest the Lithium, as you won't be using the wipes as much as you think after you burn through a few of them. I had a buddy who bought a Wolfman for the same reason, and thought the same thing about the wipes, and then he quickly realized it wasn't really worth the hassle. So he just shot the wipe out, and left it in the can and hasn't replaced in a few thousand rounds. LOL
