Primary extraction is an extremely underdeveloped but crucial stage of cycling your firearm. Primary extraction is one of the major causes of rifle malfunctions yet the design has not changed significantly in a century. In a conventional bolt action rifle, the primary extraction is conducted in approximately the last 5 degrees of bolt lift. This creates considerable shock loading on your extractor and brass to the point where the extractor can let go and drop the rifle cartridge.
The HYBRID uses an advanced primary extraction system wherein primary extraction is achieved throughout the entire 90 degrees of bolt lift. This spreads the load over a range 18x greater than conventional design in turn reducing the stress on the fired brass and your extractor while increasing reliability.
