I spent quite a few years doing Remington warranty and did replace a lot of extractors. However, every case was an example of failed quality control rather than a failure of extractor design. The 700 design is an improvement over the 722/721 design.
An ejector isn't an extractor. I don't believe extractors are available for the 722/721 rifles but I've been wrong before. GD
Hey greydog, giver her a break. Some women i've been with wouldn't know the differnce between a pickup and a sedan. You know how it is.
