This is a custom made barrel nut for a Chinese pattern Grease Gun.

THIS WILL NOT FIT A USGI GREASE GUN OF ANY VINTAGE.

The threads measure 47mm x 1.5mm pitch. These are entirely handmade and will vary considerably in shape and finish between them.

No barrel is included and a pin hole must be drilled for the barrel mounting.  The barrel hole is about .7450” for an interference fit with your barrel.  Some final reaming may be required.
