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

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.

Dimples in Magazine Tube of Remington 870

I have received answer about dimples in magazine tube from the first hands, directly from the Remington:

“The dimples in the magazine tube is to keep the new style retainer in place. If the
dimples are removed, the retainer would not stay in place. We do not recommend these
dimples to be removed. This style was introduced in the late 80’s.”

Thanks to the Remington for this information.

But if you want to install magazine extension you still need to drill them out first.
