LRI AR-15/M-16 Extractor for Remington M700 style bolts
Machined entirely in house the LRI version of the Magnum AR15/M16 extractor offers a more reliable alternative to the OEM Remington type.
Our extractors begin as bars of 4140 Chromoly and are in a parkerized finish. Springs are made from a slightly heavier wire gauge to increase shell pressure upon captivation of the case rim.
Cross pins are heat treated, ground, and rated to a breaking strength of 1400lbs.

Where the full-size extractor is made in left and right-hand versions, the mini is small enough for the same extractor to be used in both configurations.
Note* Over the years, there have been instances (very few, but they have happened) with extractor claw failures. The claw feature would literally break off from the extractor body. Efforts to mitigate the problem by altering the heat treatment (hardness level) were met with intermittent success.
In the summer of 2021, we decided to revise the design slightly by adding more material around the claw area of the extractor. Doing so resolved the failure issue by increasing the strength and durability of the claw feature. A consequence of this, however, is an issue specific to the magnum extractor installation.
Because the case rim diameter on a magnum cartridge is larger than a .308 diameter case, the extractor must pivot further away from the centerline by a small amount as it slips over the case rim to gain the required purchase. Because Remington-style barrel tennons use a counterbore feature on the breech face, the outer portion of the extractor is likely to interfere with the inner breech ring of the barrel as it attempts to slip over the cartridge case rim on the OEM inside diameter.
Determining this is easy as it's literally a "Pass/Fail" exercise. If the bolt fails to close on a loaded chamber after the installation of a magnum extractor, it's almost a certainty that the breech ring ID interference is the problem. Solving this problem requires the barrel to be removed from the action and the inner ring to be opened up slightly in a lathe with a boring bar. It's a very simple process for any vetted gunsmithing shop to perform.
LRI balances this small inconvenience against the increased reliability. We feel it's worth the effort as it makes for a much more robust and reliable system. Any shop performing this level of work is likely to be experienced with this minor detail as it's a very common occurrence with other M16 extractors used for M700 actions.
