I'm planning to order a new bolt for my Rem 700 from PT&G and have a couple questions. First the inside diameter of my raceway is 1.0035 does that sound right? Second I have an option for either Remington, Sako or M16 extractor cut, what is the difference between these extractor types? If I got the Sako or M16 cut would I have to find those parts to assemble the bolt? Would I be able to use parts from my Rem bolt if I got the Rem extractor cut? Thanks in advance for any help.
