Lubing the Beast (870)

Thanks for folks advising on the trigger group pin removal on the other thread...

The tear-down and reassembly was really easy once i got the "pin" thing...Next time it will be done in no time...The bore was filty as crap - guess the greased it up for sale...

There was very little info on what to lube or not to lube; and I could not find a video on line either...I just used my judgement based on experiance with my pistols and M1A...

But two question if you guys don't mind:

1) Do you lube the bolt assembly and firing pin? (i lubed most of the bolt assembly - black "shell" and whatever the gray colered piece which floats inside is called...But I did not lube the firing pin, bolt face, and back of bolt).

2) what is general concensus on grease vs oil for the 870 for folks who have had it a long time?

Thanks appreciate your feedback.
