The KDG HK 556 m-lok rail is a direct mount rail system replacing the factory HK 556 rail systems. The rail offers a more ergonomic m-lok rail system that is also lighter, and longer than HKs standard rail. The profile of the KDG rail allows for maximum ergonomics for the operator. M-lok attachment slots not only offer improved modularity, but added weight savings over Picatinny. The KDG HK 556 rail comes in two lengths, 10 and 14. It features a continuous monolithic picatinny rail at the 12 oclock position, and m-lok mounting slots at the 3, 6 and 9 oclock positions.

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.
