OK, so I have a tough question for all you Remington 870 gunsmiths and armorers. Several hours of research on the Internet last night failed to resolve the issue of the quality of the MIM extractor on the new 870 Express models that are being made these days. Are they inferior and subject to failing??? Should they be replaced? The Remington website was no help at all. Midway sells three different extractors for the 870 12 Ga.: The one noted as 870 Express, manufacturer’s model number F99046 for around $8.50 that I assume is MIM, the one noted as 870 Marine Magnum, manufacturer’s model number 97597 for around $10.50 that appears to be stainless steel or chromed steel and the one just noted as 870 manufacturer’s model number F16176 for around $13.50 that must be the forged steel version. The problem with the Midway website doesn’t give any description of the material used and a web search of the manufacturer’s part number doesn’t reveal anything either.
I have the Remington 870 7-shot Tactical model #25077 that seems to be somewhat of a hybrid, but I assume it’s a stealth Express with the MIM extractor. Just to be safe I ordered an extra 870 extractor, plunger and spring from Midway all described as for the 870 Marine Magnum for my parts kit. They all appear to either forged steel in chrome or s.s. and not MIM. Some sites on the Internet claim the Marine Magnum is just a nickel coated Express model with the same MIM parts as the regular Express version, but I don’t think so.
What is your opinion of the Express MIM extractor issue? Is it being overblown or is it real? Should I change out the extractor that came in my gun now, or just hang on to it in my extra parts kit? Does anyone know the skinny on the Marine Magnum’s construction and what the parts (especially the extractor) are made of?
