Gunsmithing Bolt Disassembly : Mossberg Model 83 .410

[03psd]

I inherited a bolt action .410 from my FIL. Its a Ward Western Field model. I think this is a rebadged Mossberg 83. It hasnet been fired in decades. I am refinishing the stock and giving it a real good cleaning. Anyone know how to disassemlbe the bolt?

Thanks
