The Scarging handle fits both 5.56 and 7.62 NATO versions of the NRCH FN SCAR and installs in seconds. The geometry of the Scarging Handle allows a superior grasp and additional leverage when charging, clearing stoppages, and administratively locking the bolt to the rear. Choose between left or right-side installation (or both), in either an upwards or downwards sweep. The downward sweep protects your hand from busting knuckles on optic mounts and other accessories by angling the charging handle down and away from the top of the weapon. Scarging Handles are constructed of low carbon steel and finished with black Nitride or FDE Cerakote made 100% in the USA.
