Like the HK416, the HK417 was developed by Heckler & Koch with internal funding working directly with special operations forces personnel. The 7.62 x 51 mm NATO caliber HK417 Weapons System is designed as a Commercial Off-the-Shelf (COTS) alternative to existing, competing 7.62 mm semi-automatic and select-fire rifles, carbines and sniper rifle systems. As the .30 caliber "big brother" to the combat-proven 5.56 mm HK416 family of rifles and carbines, the HK417 shares the operating control location and functions, disassembly and maintenance procedures, and ergonomics of the HK416 and other AR15-based weapons, including the US M16 and M4-type rifles and carbines. This fact insures immediate operator acceptance and transfer from one weapon to another and retains the already learned muscle memory critical to proficient target engagements when under stress.
