Sako Extractor Upgrade for Rem 700 Works Great

Sako Extractor Remington bolt

Jonathan Ocab, a High Power shooter from California, had gunsmith Doan Trevor install a Sako-style extractor in the Rem 700 bolt in Ocab’s 6mmBR Eliseo R5 tubegun. Jonathan produced an excellent video showing how the Sako extractor improves the ejection of the short, fat 6mmBR cartridges in his rifle. Jonathan’s video demonstrates 6mmBR case ejection with an unmodified Rem 700 factory bolt versus a factory bolt fitted with a Sako-style extractor.

Johnathan explains: “Note how even when slowly operating the bolt, the bolt with the Sako extractor easily ‘kicks’ out the brass on ejection with minimal chance of operator error resulting in a failure to extract. While the unmodified bolt has issues ejecting brass on slow operation, it will eject if the operator pulls the bolt back quickly (fast and with some force).

While a Sako-style extractor isn’t an absolute necessity, this video shows the definite improvement this modification provides. For short cartridges like the 6mmBR, this is very useful. This modification is highly recommended for competition shooters, especially High Power competitors who seek improved function in rapid-fire stages. This modification is fairly inexpensive and any competent gunsmith should be able to perform the work (usually under $100 with parts and labor).”

EDITOR’s NOTE: In his video, Jonathan deliberately worked the unmodified Remington bolt slowly to show how the standard Rem extractor can struggle with short fat cases like the 6mmBR. In fact, when you work a standard, unmodified bolt more quickly, the extraction can be much more positive. Cycling the bolt with more “snap” provides more energy to eject the cases. We have run an R5 Tubegun chambered in 6mmBR with an unmodified Rem 700 bolt (no SAKO extractor), and the extraction was reliable, provided the bolt was worked quickly.
