Remington 870 Extractor Replacement (How to Install non-MIM Extractor)

11 March 201118 comments Accessories, Advice, Best, How-to Videos, Upgrades, Video

One of the simplest ways to improve your shotgun’s performance is to change a standard MIM (Metal injection molded) extractor with non-MIM (solid steel) extractor. Steel extractors are used on the Remington 870 Police shotguns because they are more durable and allow heavy use of a shotgun.

Changing the extractor on a Remington 870 improves reliability. New extractor is inexpensive ($10-15) and easy to install.

How to change the extractor on a Remington 870 shotgun:
1. Check that your shotgun is unloaded. Check both magazine tube and chamber.
2. Disassemble your Remington 870.
3. Take out the bolt.
4. Put a flat head screwdriver between a plunger and the extractor.
5. Pull the extractor plunger back to depress the spring which is located behind it. Then lift the extractor out rotating it.
6. Take the new non-MIM extractor and push it rotating in until it snaps in place with click.

I have created following video to show you how to change the extractor on a Remington 870:

    Hi, I just purchased a 870 express tactical 12 guage and I am completely satisfied so far. I am looking to change my factory extractor to a steel extractor, however I cannot find the steel extractor to purchase anywhere on the internet. If you can please inform me of what site I can go to, so I can make a purchase of the steel extractor I would greatly appreciate it.

      Louego, I have ordered mine on Brownells.com

    Does the Wingmaster version come with a solid steel version?

  5. Alpiner May 10, 2012

    Seems like you need a follow up post. What is the AGI mod? Is rounding the edge really worth the effort? Who sells the best extractor? Thanks!

  6. Vitaly Pedchenko May 11, 2012

    Alpiner, the best extractor is non-MIM extractor by Remington. It is used in Police version of the Remington 870.

    Yes, rounding extractor is a good idea.

    Hello,
    Bought your book. Is there a video on this. Not quite clear from pictures in your book as what part of extractor to round and how much?

    Thanks

    Rick, I will try to make such video asap. If you have non-MIM extractor – it is already much more reliable than MIM extractor.

      Vitaly,
      Did you every make a video on the extractor modification. Exactly where and how much to take off.

      Rick

        Rick, not yet. Very busy getting ready for the World Shotgun Championship. Will do this in October.

        • rick October 20, 2012

          Vitaly,
          Any date yet for video on extractor modification.

          Rick

          • Vitaly Pedchenko October 24, 2012

            Rick, sorry for delay, will try to do this asap.

    I called Remington today. I have 3 870 .. 2 12 ga and a 20 ga.. I talked Aron ?? I told him all three have not been extracting the shells.. he wanted me to send all three back now durring the hunting season??? I asked him if there were any recalls or customer complaints and he said non that he had heard of…REALLY !! I told him to google it on the net… He was a bit butt hurt after that… All I wanted were the extractors.. Very bad customer service… I will keep calling untill I get someone who knows what they are doing over there … Anyways will the non-mim fit both 20ga and 12 ga?? Thanks

    Good morning Mr. Vitaly,
    I have a question concerning the extractor please. Last week I took my 870 Tactical to the shooting range with both a box of plain bird shot and some low recoil 00 buck I purchased at a gun show. My 870 ate and ejected the 00 buck as easy as you please and I was very happy. However, when I went to fire the bird shot I could not cycle the weapon at all. The bird shot had a small brass “base” just a few mm tall whereas the 00 buck had the taller “base” that is aprox. 1.5 cm tall. Will my stock extractor not cycle the shorter brass ammunition? By replacing my extractor with a non-MIM extractor will that fix that problem? I enjoyed shooting the weapon immenly but naturally cannot afford to shoot nothing but 00 buck in it. Thank you for your time concerning this matter!

    • Vitaly Pedchenko May 8, 2013

      Good morning Joseph,

      Remington 870 doesn’t like low brass ammunition. This is common problem. Non-MIM extractor may improve this but not much. The only solution is to experiment with ammo and find the ammunition which you can use without problems.
