The Scarging handle fits both 5.56 and 7.62 NATO versions of the SCAR, and installs in seconds.The radius-faced design, and swept geometry of the Scarging Handle allows the user to achieve a more solid grasp when manipulating the bolt. This allows for easier charging, clearing of stoppages, and administratively locking the firearm bolt to the rear. The shooter can choose between left or right side installation to match their hand dominance, and can rotate the Scarging Handle to either downward or upward sweep. The downward sweep protects the hand from "busted knuckles" due to optics mounts by keeping it down and away from the weapon's top. This also has the added benefit Mfg: Kinetic Development Group SPECS: Works on all 7.62 and 5.56 SCAR models, Black FInish, Ambidextrous for Left or Right Hand Shooters, Materials: Material: Low Carbon Steel, Finish: Non-Reflective Black Milspec Finish 100% Made in the USA.
