Hi CGN'ers

I've got an 870 Police shotgun. Just wondering where and how much lube you use on this thing after cleaning. I've got it all apart no problem. I read the manual online at Remington...all it says to do is lube the trigger group. Does that work in the real world...no lube on bolt group, slide rails ect?

Any advice would be appreciated.

Thanks,
BongoBob
 
Just give everything a light coat of oil and wipe most of it off. I put a couple drops on the receiver, mag tube and barrel, wipe it around with my finger and use an old rag to wipe it off. I do the same for the internals too and put a little drop on the ejector and slide arms.

Essentially just give things a very light coat and do not over do it.
 
I used some newly gotten moly dry lube on the inside of the pump tube and outside of the magazine. It sure slicked up the feel and it's holding up well and doesn't attract dirt. Another option for this would be some floor wax rubbed onto the same surfaces but it'll need to be redone more often. Oil on these same parts would obviously work but it would be messy and hold dirt.

On all the inner workings I did exactly what Nonus said. Oil is really tenacious stuff. A light wiping after the application will still leave a "just right" protective film.
 
It depends what you are going to use it for. If you are going to store it and only use it occasionally, then light oil is fine. If you are going to use it often, then some grease will be helpful. Oil will attract dirt, and so will grease, no matter what. The only gun that doesn't get dirty is a 100% dry gun in a box under your bed- your 870P is MADE to run dirty. I would oil/grease the rails and the bolt (not the bolt face), and lightly wipe the spring with oil (for maintenance)- but don't leave any oil in the magazine. Some oil in the trigger group is good, but not too much as you shouldn't have to go near the trigger group often. Don't over do it on the lubricants, but after you shoot it a fair amount you will know how much YOUR shotgun needs to be lubed after it is broken in.

-when you are done and it's reassembled, nothing should drip off of the gun- that means it's too wet
- there should be a health "cachink" when you cycle the action but not a metal on metal nails on the chalkboard scraping- that means it's too dry
 
I take mine apart and soak it (everything, every single part including the barel) with G96 gun treatement/oil, let it soak a bit then wipe.
 
For lubrication Remington says three drops in the gun as follows:

1) One drop on hammer plunger
2) One drop of carrier dog plunger
3) One drop on extractor plunger

and one more on the barrel ball detent if you have one.
