Remington 700 rifles often get blamed for mechanical faults that were actually the owner\gunsmiths fault. The extractors that I have seen fail were the result of refinish jobs. The caustic involved with the refinishing process either ate the solder holding the extractor or the solder and the extractor. This also goes for bolts coming apart. Refinishing by a less than competent (would be)smith was always the cause. As for plungers failing. Hosing them down with a good synthetic oil and working the plunger with a screw driver or punch, then brushing the bolt face with an old tooth brush once and a while will take care of any plunger problems. Lack of maintenance and improper hand loading and handling will be an anathema to any brand of firearm. With Remington 700's being so popular, and reasonably priced, more morons own and handle them.
