Ok guys, who do you recommend to machine in an m-16 extractor in my Remington 700 SA .473 bolt? Keep in mind I paid good money to have a Sako style extractor machined by some "famous" people and it just pops out every now and then. Is it fixable as a Sako style? Will the m-16 extractor be adaptable with the Sako cut in already? Let me know.
