Remington 870 Non-MIM (Machined) Extractor
An extractor is a part found in most firearms. It removes the spent cases from the ammunition that gets fired after you pull the trigger. With Remington 870 extractors, you can use a non-MIM or a MIM extractor for the shotgun. MIM stands for metal injection molding. Newer Remington 870 shotguns use MIM extractor. But the good news is that you can replace the MIM extractor with a Non-MIM extractor.
Non-MIM extractor, which is commonly referred to as a “machined extractor,” is an upgrade for the Remington 870 that many gun owners are more comfortable with. The Non-MIM is known for insuring that fired shells get extracted properly and without any problems. A big complaint people make about the MIM extractor is that it breaks too easily and that it is unreliable.
For anyone who owns a Remington 870, it won’t cost a lot of money to replace the MIM extractor if it breaks off. The non-MIM extractor is very inexpensive and easily to install as an upgrade for your weapon. It will also make the extraction of fired shells much more reliable in your weapon than it did with the MIM extractor.
If you look at the police version of the Remington 870 shotguns these days, they all have non-MIM extractors in them because of their reliability. For all gun owners who still have a MIM extractor in their Remington 870 and find it unreliable, it will only cost you around $15 to replace the MIM with a non-MIM. This is one of the best and most cost effective investments you can make in preserving the quality and reliability of your Remington 870.
Non-MIM or Machined Extractor
Machined extractor is one of the must-have upgrades for your Remington 870. It insures reliable extraction of fired shells. Police version of the Remington 870 utilizes non-MIM extractor too because it is more reliable.
If your Remington 870 has problems with extraction – changing extractor is the first procedure you need to do. This upgrade is not for looks it is for reliability. Better non-MIM extractor costs just $14.99 but improves your shotgun dramatically.
Non-MIM extractor is my first recommendation to Remington 870 owners which starts upgrading their shotguns. Most shooters spend hundreds of dollars on tacticool upgrades but rarely upgrade inner parts. This is one of the cheapest but the most important upgrades you can make to Remington 870 shotgun

Non-MIM, solid steel extractor is better than MIM extractor. Solid steel is more wearproof than stamped metal. When extractor hook begins to round off, you can have problems with extraction of fired shells.
