Where can I order a USGI castlenut for my GI M-14 barrel

[chalkriver]

I picked up a partial Norinco M-305 and I can tell the barrel has been off before . The factory made 18.5 inch barrel and hooded gas lock front sight on the rifle now don't have Chinese threads so I am assuming the castle nut for the flash hider doesn't have Chinese threads either . I don't have a castle nut to try on it to confirm though. Previous owner had no info about it at all.
Where can I get a castle nut for the flash hider with GI threads ?

The SEI Hooded Gas Lock front sight looks like this except mine has OIF SEI stamped on it as well as USMC underneath those lettters

treelinem14.com has em for $9.00 USD so thats about $5000 CAD if you have the spare change . keep in mind when ordering from treeline the $21 flat rate shipping regardless of what you buy and it what quantity.

I thought the usgi and chinese castle nut threading were close enough to be interchangeable.

I've got usgi castle nuts on my chinese barrels
