By the way, Heckler & Koch (HK) was going to name the HK416 the "HK M4", but then they got into a dispute with Colt on the rights to using "M4" in their name, so they just called it the "HK416". So you could call this an M4, although their designs are way different. The HK416 is essentially an improved version of the M4A1.
