Difference Between Hk416 and Mr556

What is Hk416?

Hk416 is a type of metal alloy that is used in the manufacturing of Mr556. The abbreviation Hk stands for Heckler and Koch, which is the company that originally developed the metal alloy. The 416 refers to the specific mixture of metals that are used to make the alloy. HK416 is a 5.56×45mm NATO assault rifle developed in Germany by Heckler & Koch. It is derived from the AR-15 and the M4 carbine, and is one of the most advanced weapons of its kind. The HK416 uses a gas-piston operating system rather than direct impingement, which means that gas from the fired round does not go back into the weapon’s action, but instead vents out of a hole in the barrel near the front sight assembly. This method of operation reduces fouling in the action of the weapon and prevents hot gases from blowing back into the face of a left-handed shooter, who would otherwise be hit with gas or blowback from directly behind their face.
