- Airsoft Rifle
The HK416 was developed by Larry Vickers and Heckler & Koch. It was named H&K M4. Because Colt Defense had the trademark for the M4, the name had been changed to HK416. SR416 is one of SR4 family members. The design of SR416 has some similarities with SR4. For example, they all have symbols of Safe, Semi-Automatic, and Automatic; they all use one-piece handguard.
