Those images visible now ?
Sure are, why does it look like you screwed the nut on backwards? The teeth face the muzzle.
Edit: looking at the magdump handguard ad it looks like you have the nut mounted correctly, it’s backwards to any other design I’ve seen. It also looks like an eBay special, which could be the issue.

I know who they are, doesn’t mean the product they sell isnt manufactured the same place the eBay stuff is. That handguard is available on eBay. It’s also a very low price, no North American manufacturer can produce it for that price. Just stating facts. Other Canadian companies do this, not saying MagDump does.
Well I have to make it work for now until I do a rebuild to an MK18 possibly (or find a Bull Barrel accepting hand guard for less than $100 that I like and can use)
My offer still stands, if you can't 3D print the barrel nut wrench.

Notice the little step below the teeth, that's your problem.
Mine doesn't have that.

It can fit a standard barrel nut backwards.
