I am trying to replace the factory MIM extractor on my Remington 870 Express with a steel extractor. I originally ordered the part from Brownell's, attempted to install it, and it would not fit properly. I was informed that Brownell's likely sent me the wrong part, so I returned it and ordered the steel extractor directly from Remington. After waiting 2 weeks for the new part to arrive, I went to install it and it does not fit into the bolt either.
The first picture below is of the bolt face. Notice the sloppy uneven cut-out where the extractor fits into it. I don't own another 870 to compare with, but this doesn't look right to me. The second photo is of the two different extractors, the steel part on the left and the MIM on the right. Notice how the edge of the MIM part is chamfered unlike the steel part. This chamfer is what's allowing it to fit into the bolt. Is the MIM part typically shaped like this or was this particular one likely ground down to fit into this particular bolt?
