I have just found a good video of how to dissasemble the Mossberg 500
and since its almost the same as the 600at (infact, i don't even know what the difference is between the 500 and the 600at), I decided to have a go at stripping my gun.
In the video, the bolt assembly clearly has a 'spring' in it.. Where as on mine 600at, it doesn't.. Does anyone know if it should be there? Perhaps this is the difference between the 500 and 600?? If it is needed, what are the implications of it not being there? Could I simply order the spring and fit it myself (although this will require dismantling the bolt assembly, which may be something that a Gunsmith should do).
Also, when re-assembling, is it a good idea to lube the parts? If so, what with Gun Oil? Grease?
Any info on this would be appreciated
Jon
