I have close to 30k rds through my 870, and ive started having issues with it. (shells not coming out of the mag, failing to extract, action is not as smooth as it once was, ect)
Right now im debating between a complete rebuild, and just replacing the damn thing. If I go with the rebuild, im going to replace everything but the bolt, barrel, receiver, and trigger group. Meaning, all new springs, new follower, new extractor, shell catches, action bars, lengthen the forcing cone and ceracoat it. I can do all of this, except the ceracoat, which I'll have to send it off for. (just dont have the equipment for, and if I use the oven in the house my girl will kill me) The other option is to replace it with a brand new one, and swap over the surefire forend. Less work, and no turn around time, plus I get to buy a new gun but I wont have the satisfaction of having done the work myself. There is only like an $80 difference between the two, that in mind, what would y'all do? |

When you've owned and shot something for that long you tend to get attached to it. But think about it from this perspective. Will you get a better product if you replace it or rebuild it? If the cerecote finish and mechanical rebuild will bring it back up to your expectations, stick with it. I'm assuming its an older 870, so be aware replacing it with a new one may be a bit lackluster with the way Remington is building them now. Not to mention yours fits like a glove mechanically after all that use. |

I have an 870 Express that I purchased new sometime in the late 80's. It's been shot. I have replaced the extractor and magazine spring once. These guns get slicker with use. If your action is "not as smooth as it once was" after 30K rounds, something doesn't seem right. |

Did you mean you shot 3,000 or 30,000 rounds through 870??? Quoted:

Considering how well the 870 wears and lasts, you may be over-doing the rebuild effort.
By all means replace all the springs in the trigger unit, bolt, and if it has a standard 4 shot magazine, buy a new Police version magazine spring. The Police model spring is stronger and assures positive feed. As for the rest of the gun, get a couple of cans of gun scrubber and give everything a really thorough cleaning. Put some effort into blasting out the back side of the shell stops and inside of the receiver. Shell stops don't wear much and all that may be needed is a good cleaning to get impacted fouling out from the back side to restore spring action. Use a really big bottle or 10 gauge bore brush and solvent to clean out the magazine tube. Replace the magazine follower with your choice, but I don't recommend aluminum or steel followers. The Wilson/Scatter gun green follower is excellent. Dry thoroughly with a hair dryer (Note: Hair dryer, not a torch, heat gun, or oven). Then apply a good lubricant like CLP Breakfree, making sure to get some behind the shell stops. I apply a few drops of CLP to a soft toothbrush and "scrub" all surfaces. This will leave a thin layer of lubricant to lube and prevent rust. For key areas use a little grease. Check the action bars with a straight edge. Unless the bars are actually worn badly they are seldom bad and all that may be needed is to straighten them. Use the straight edge to check for bends in any direction, and for kinked bars. You want the bars to be in a line with the tube portion of the assembly and spread just slightly apart. Bends or kinks upward or downward can cause stiff operation. Just this little work may be all that's needed to put the gun back in perfect running order. Unless you have an airbrush set up, ceracoat is a good way to go, and ceracoat durability is excellent. |

id send it off to Hans Vang, and have him work his magic on it. Vangcomp does some awesome work. as soon as my stamp comes back for one of my old police models, (since replaced with a new police model) its going to him to get chopped, and tricked out.
that being said- if you find a true remington 870 police magnum, its still a really good shotgun. they are built by hand, one at a time, on a separate assembly line. almost twice the price as an express model, but in my opinion, its twice the gun- out of the box. |

I believe that is no longer the case, it is now a matter of a shotgun being a shotgun. |

Because I really dont have a use for two 870s. Fwiw, its not that old, maybe 5-6 years. I just shoot alot. Quoted:

Why not buy a new one, swap the fore grip, and then rebuild the old one bit by bit if money is an issue? Because I really dont have a use for two 870s. Fwiw, its not that old, maybe 5-6 years. I just shoot alot. Have you contacted Remington about your many problems? They maybe able to help. PITA45 
PS One is none and two is one!
