Anyone out there have an older, early 80's, Rem. 700 in 7mm Rem. mag with a rivetless extractor? Remington says all magnum 700's have riveted extractors, but I disagree. Mine appears to be rivetless, but just wanted to see if anyone else also had a magnum 700 with a rivetless extractor..The part is not available..Only riveted extractors are available for Rem. 700 magnum bolts...Any ideas? Thanks.
