The development of the HK416/417 sought to cure the design problems associated with existing M16 rifles and M4 carbines, inherent to the 50+ year old design. The key improvements, made by HK, are their patented self regulating short-stroke gas piston system, borrowed from HK G36 rifle. Other improvements include new buffer assembly, improved bolt, and a cold hammer forged barrel, as well as free-floating hand guard with integral picatinny rails.
