The F2000 uses a unique ejection system, ejecting spent cartridge casings forward and to the right side of the weapon—through a tube running above the barrel. This method of ejection provides for fully ambidextrous operation; the rifle can be used without any modification by both right and left-handed shooters. This ejection pattern was achieved by using a swiveling polymer tray, which intercepts the empty casing from the bolt face immediately after disengaging from the extractor. As the empty casing is extracted it is held while the rocker assembly tilts to lift it above and clear of the feed path as the next round is stripped from the magazine by the bolt head. The casing is fed into the tray located in a cavity in the receiver wall, which then pivots the cartridge case and directs it into a chute (above the barrel); the case is discarded from the tilting tray by being impacted by a pin on the moving bolt carrier upon its forward return. Only when the ejection tube contains more than five cases is the first of them ejected forward through a port just behind and to the right of the muzzle. This is continued; every fifth round fired, all five shells are ejected in a burst, until the magazine is empty. Thus a 30-round magazine will be ejected in six bursts of five shells.
The F-2600 Inline Vortex Flow Meters are available in sizes ranging from ½" to 12" in diameter and are available with flanged or wafer process connections. The maintenance-free design provides accurate and reliable mass flow measurement.
