Daystate Wolverine R shroud

Use a hair drier on high heat where the shroud meets the block, be patient and let the heat soak in, should come right off.

If they use the same type of epoxy that is used to bond the moderators, it will take more heat than a hair dryer. I've had to use a torch to get the silencers off, since I don't have a heat gun, which is probably the best tool. 
 
Mine may have been one of the first shipped out when they hit the U.S. It is threaded on with no set screws. Set screws may have come in later versions.

If your issue is not being able to get a good enough grip on the shroud to unscrew it, you may have to get creative in finding a method of unscrewing it using more force than you have been able to apply..

I am going to tell you what was successful to me when faced with this on mine. I don't need to know how crazy I am from other posters, I already know that and need no reminders.

The boys at AOA are very careful when it comes to "lead dust collectors" and sent me a shroud with an LDC attached to it in lieu of just sending an LDC alone. This was due to a miscalculation on their part that they made good for (👍 to them). I had to remove my shroud to replace it with the one that was sent so I could send the original back. Like yours, it didn't want to move.

Duct tape to the rescue. I tightly wound, did I mention tightly, around the shroud as low to the receiver as possible. Lots of layers to be exact, lots of them. I then took a plier with curved jaws and gripped the tape as tight as I dared. At some point the shroud will distort, so I stayed clear of what I though that point may be. These were locking pliers so they stayed in place around the tape. Then heated the base with a heat gun on low. Slow and steady she goes.

When I felt enough heat was applied I gave the pliers a sharp shot with a rubber mallet and the shroud broke free. There was no evidence of any kind of glue or LocTite on the threads, but I will not swear none existed, it doesn't take much to hold things down.

So, no guarantee this will work for you, but you can give it a careful try if you like and if you do, let us all know the results.
 
That all makes me nervous. I'm a wrench guy but with things as nice as that Wolverine I can see something slipping and an "oh crap" moment. I bought it new from AoA so whatever is on it came from Daystate. It's holding the barrel that had proven difficult. Maybe a padded vice?? I think I'll price a new shroud 1st so I know how much is at stake. Lol!!
 
Seems to me, you have nothing to gain by removing the shroud, with considerable downside risk if you screw it up. Let's say you get it off, and in the process partially crush or scratch up the shroud. Okay, you can see and feel the barrel. And for that experience, you need to buy a new shroud. Maybe it's just me, but I'm not sure there's a lot of common sense at work there. That said, I share your neurosis about the need to see how things are put together. Good luck.
 
I hadda little trouble with one of my shrouds and the moderator. I used 2 of those rubber strap wrenches, they come in a package, one small, one large, made by Craftsman. I put some 2" wide 'Transtex' tape (looks similar to electrical tape, but much wider) around the barrel and shroud to give is some grip and with a little muscle, they separated. Not too bad, no heat. Maybe with a little heat just to the shroud but not enough to heat the block might help as that should sell just the shroud without swelling the block.

Good luck!
