HK416 is an obtainable Tactical Doll in the game.
The Heckler & Koch HK416 (HK M4) is an tactical rifle/carbine designed and manufactured by Heckler & Koch. It is based on the AR-15 platform, and was originally conceived as an improvement based on the Colt M4 carbine family issued to the U.S. military, with the notable inclusion of an HK-proprietary short-stroke gas piston system derived from the Heckler & Koch G36 assault rifle.
The United States Army's Delta Force, at the request of R&D NCO Larry Vickers, collaborated with the German arms maker Heckler & Koch to develop the new carbine in the early 1990s. During development, Heckler & Koch capitalized on experience gained developing the Bundeswehr's Heckler & Koch G36assault rifle, the U.S. Army's XM8 rifle project (cancelled in 2005) and the modernization of the British Armed Forces SA80 small arms family. The project was originally called the Heckler & Koch M4, but this was changed in response to a trademark infringement suit filed by Colt Defense.
Delta Force replaced its M4s with the HK416 in 2004, after tests revealed that the piston operating system significantly reduces malfunctions while increasing the life of parts. The HK416 has been tested by the United States military and is in use with some law enforcement agencies and special operations units. It has also been adopted as the standard rifle of the Norwegian Armed Forces.

- A member of the 404 squadron along with SMG UMP45, SMG UMP9, and AR G11.
- HK 416 holds a deep disgust against the members of the AR squad (especially against AR M16A1) despite being a AR-15 derivative.
- There is a "blood tear" tattoo under HK 416's left eye. It is based on the HK's defeated in a lawsuit against Colt about the copyright infringement of the name of "HK M4". This incident is also built up HK 416's hatred and sour rivalry against the AR squad.
- As one of the furniture stated of "Don't give Alcohol to HK-416" might stated that she has a poor tolerance to them aka "gets drunk easily".
