I just ordered a police trade-in 870, sight unseen. It's a magnum receiver wingmaster.
Are there any parts or springs that I should expect to replace? I'm already going to order a +1 extension before I pick it up, and I wasn't sure if there was anything else I should include in the order. |
Most of the police trade-ins I have handled (which has been quite a few in my lifetime) may look like Hell on the outside but are often pristine (if a little dusty and dirty) on the inside. I would replace the mag spring just because it is cheap and easy and the most likely part to "wear-out". Otherwise, I would give everything a good cleaning and inspection and then shoot it for a while to see if any problems manifest. Pump shotguns in general and 870s in particular are not prone to breakage. I have an 870 EXPRESS (the horror ) that I purchased in 1994 and have used as a beater gun for 20 years. It looks like shit but has all it's original parts including the mag spring and follower.

Thanks all, That's what I was hoping to hear. It's cheap enough, so I'll order a replacement spring for the factory 4+1 tube in case i want to remove the extension for whatever reason. Make sure to buy a POLICE 4-shot magazine spring. The Police springs are stronger. This is to insure proper feeding when the gun is fired fast with buckshot or slugs. Check the "carrier dog" (shell lifter) spring. This can weaken and cause the shell lifter to not move up far enough or fast enough. CLEAN THE GUN WELL, inside and out, including using a big brush and patches in the magazine tube. Use Rem-Oil to liberally spray out the trigger group. Shake the excess off then stand it up on a pad of paper towel to drain. This will clean out the gunk. Do the same to the area behind the shell stops, only you can use a gun scrubber spray to blast the gunk out. Dry, then spray in some Rem-Oil. |

Thanks for the tips dfariswheel

My police trade in had a weak mag spring, deformed follower, and a cracked extractor (the piece held in by the two rivets). My Dad's had a weak mag spring and the wrong type of follower installed for his length of mag tube extension. FYI. Damn, I sure hope the extractor isn't damaged. What did it cost you to have replaced? |

I think the poster meant he had a damaged EJECTOR.
The ejector and long flat spring are riveted into the left receiver wall. Replacement requires a trip back to Remington to get it properly replaced due to the rivets through the receiver wall. Cracked or broken Police or Wingmaster ejectors are not common, so I wouldn't be concerned until you look it over. A EXTRACTOR is an easy replacement and I forgot to add that you should disassemble the extractor, spring, and plunger from the bolt and clean them and the tunnel in the bolt. Removal is easy. Just get a small pocket size screwdriver and round off the sharp edges and corners. Use it to pull the extractor plunger back and slip the extractor out. Then remove the plunger and spring. |

Quoted: Thanks again, just checked YouTube. As expected, a bunch of detail strip, cleaning, & lube videos for the 870. Should be a fun & dirty night when It arrives.  |

Maybe not. I just got mine, and when I took it apart to do a clean and inspect, it was basically like new inside. Quoted:

What did you have to give for it? Did it come from summit? Just bought a Puerto Rican 870 Police magnum for $225 and a Winnie 1200 for $135, it was an instant riot gun collection!  Yep, ordered from Summit. I think it ran me $275 before shipping and the FFL transfer fee. Can't wait to pick it up. FYI Mark said he should have a batch of Wingmasters going up in the near future. |

Remington 870 shotguns are designed to be treated like mail order brides - rode hard and put up wet. A can of Gun Scrubber, an old tooth brush and Rem oil will probably be the only requirement.
Check sight alignment on slugs, otherwise run and gun with it. I own a 870 purchased in 1978 new for $195. Polished blue looks faded compared to a new one but it runs flawlessly. 28" ventilated rib with a modified choke shoots slugs dead on at 50 yards. That's something that doesn't usually happens and secures this gun as a permanent part of my collection. I've replaced extractor's and ejectors at home on 870's, buy non-MIM extractors through Brownell's, they're better parts. Ejectors require specialty tools to stake them in place, but can be done at home. These shotguns are very simple and rugged. Very little goes wrong with them. Upgrades and replacement parts are prolific. |

If it's marked Wingmaster or Police, then it shipped with a non-MIM extractor that is unlikely to ever fail. If you need one for your Express (You do), they're about $15. If you want to replace an ejector spring you'll need the special toolkit. It really isn't a task for a novice. If you have a 2.75" 870 and want to make it a 3" 870, the only differences are the ejector spring and the length of the chamber in the barrel. You can buy a 3" barrel or ream the one you have. There's serial number data to compare the ending letter on the Remington website and other places that will indicate which length ejector spring the receiver shipped with. They don't make 2.75" ejector springs anymore, as the 3" will work on both. The 3.5" is a whole other 870. The most expensive factory upgrade to make is a flex-tab kit, as you'll need a new bolt, bolt carrier, and fore-end tube assembly. $ |
