I think I have a paraclip but I like the simplicity and lightweight of the Frank Proctor sling which is 1". I have a Magpul and several Vickers slings and if I go that direction... I will consider the paraclip.
I am not finding much other than the magpul part and the one that screws into the stock after tapping. I am not going in the latter direction.
I will order the magpul part and deal with the full rotation.
