[QUOTE="NesikaChad, post: 492924, member: 7449"] This is my opinion so take it with the salt. Sako extractors elevate the risk of endangering the shooter because a 90* rotation, twin lug action that operates in a pushfeed capacity, offers almost zero support/captivation of the extractor when the bolt is rotated into battery. It is almost in direct line with the ejection port raceway. This part was/is designed to operate in a 3 lug gun with a 60* rotation. In the event of a violent case rupture the extractor WILL be ejected from the breech. The Sako extractor has nothing other than clever mechanical interaction and a spring retaining it in the bolt. The only support/containment it receives is by this and by the overlap created by the bolt's counterbored breech face. I know of two cases in the last year that resulted in trips to the ER to have gun parts removed from eyes and shoulders. In my professional opinion its a dangerous practice. An alternative is the M-16 style extractor that is gaining more and more popularity. It at least has a cross pin retaining the part. Last, properly installed, the factory Remington extractor is a powerful one. In many "studies" performed over and over it routinely outshines the Sako in terms of the amount of load it'll tolerate before failing. Quite often its the rim of the case that lets go before the extractor. Many of the more well known and respected smiths in this trade are moving away from them because of this. I will not service or build a Remington that uses one. Hope this helped. C PS. For the amount of money it'll cost to pay someone to install a Sako you can almost pay for a whole new bolt from PTG that'll come with the AR-15. Sweat/TIG the handle back on and your done and it's fitted to your receiver specifically. (they ask what OD you want on the bolt when you order it.) [/QUOTE]
