Bruce,

I dunno if they're dangerous or not. Have fired a lot of Sakos with "Sako" extractors over the decades, as well as other rifles with similar designs, without a problem.

I've never had the job done, partly because I've never had a 700/722 extractor break in at least 100,000 rounds fired. But have heard prices start at around $125.
