A video comparison between the Heckler and Kosh’s 416 and the Colt M4. Which one you think is better?
The HK416 is an assault rifle designed and manufactured by Heckler & Koch. It is an improved version of the M4 carbine, with many changes with respect to it, most notably its gas system, similar to that of the HK G36, in 5.56 × 45 mm NATO gauge. Military and police forces can purchase the part of the mechanism box, recoil absorber and gas system to recondition AR-15 rifles or purchase the complete package.
The unit Delta Force, the United States Army, collaborated with the German arms company to develop the new weapon. The Delta Force replaced its M4 with HK416 in 2004, after tests revealed that the piston system significantly reduces malfunction and increases the life of weapon parts.
