Description
Wagner Outer Nut for Corona Star — Genuine PEM-C4 / PEA-C4 Spare Part (390319)
The outer nut for the CoronaStar secures the CoronaStar assembly to the gun front end — the retaining collar for the 390918 set.
Shops open powder guns often, and small hardware strips or walks away. Genuine replacements keep threads, torque, and fit exactly to spec — improvised fasteners are how housings crack.
