The HK416 was an improvement of the M4 assault rifle. These improvements were made by Heckler & Koch, a German defense manufacturing company.
Improvements on over the M4 includes international symbols for Safe, Semi-Automatic, and Fully automatic, a new pistol grip designed by H&K, attached to the rifle is a new single-piece hand guard with a free floating RIS system, used for mounting accessories.
The most important change in the short stroke gas piston system used to cycle the weapon which was used in H&K's G36. This gas system makes the rifle much more reliable than the M4. However, the HK416 still uses the same platform as the AR-15 series of rifles.
