A barrel nut is an internally threaded screw with a slotted head.
All you must do is purchase an A5/X7 threaded flatline barrel and screw it in, becasue they have the same barrel threading. 98 threaded barrels will not work.

You will probably have to contact a barrel maker.
Any autococker threaded barrel.
