Play in winmaster barrel

[GunNewb]

Bought a new wingmaster barrel for an older gun. Its the 18.5 factory barrel.

The barrel shakes a bit when mounted- anyone know if this can be fixed?

I've never seen a factory wingmaster 18.5, express, tactical, rifled yes which are usually a tighter fit.
Any how what do you mean by shake?? Is the ejector end worn or bent and the barrel is going side to side slightly, do you have the right mag tube nut combo. Have you tried a o-ring behind the mag tube nut to see if it tightens up??
