Ive bought 6 new duke #2 4 coils and they seem great but the center swivel d loop is bolted on it does have a nylock nut but im wondering if anyone has gone ahead and put a bubble weld on them or is it a non-issue?

I have never messed with them but even hitting the threads with a punch should work. Its hard to tell by the picture is that center swivel very heavy. Looks like light material.

It's just as heavy as a regular D loop it might lay a little flatter than a regular d loop

Leave them be, would use them just as they are until I see they have issues. They look fine to me.

Thanks I thought that but figured id get some others opinions I haven't seen any reviews for them with this style of loops
