The H&K M-416 is an assault rifle designed and manufactured by Heckler & Koch. In Incident: 100A, Sanford briefly used one to kill several l33t agents.
In Madness: Project Nexus, its stats are similar to that of the AR-15 but with a slightly slower rate of fire. Both are inferior to the TAR-21.

|Nothing says 'tactical' like plastic guns! Piston operated, like an AK, but easier to control at a high rate of fire, like an AR. Best of both worlds.
