"The compact M4 carbine - a shortened version of the M16 - that is now standard issue for most Army troops, some Marines and other specialized units is facing increased criticism because of its tendency to malfunction with even the minutest exposure to the elements.
Some ground communities, including special operations forces, have begun to sideline the M4 in favor of newer, gas-piston operated variants such as the Heckler & Koch-manufactured 416 and the FNH-built Special Operations Forces Combat Assault Rifle, or SCAR
In a routine acquisition notice March 23, a U.S. Special Forces battalion based in Okinawa announced that it is buying 84 upper receiver assemblies for the HK416 to modify their M4 carbines. The M4 fires using a system that redirects gas from the expended round to eject it and reload another. The 416 and SCAR use a gas-operated piston that physically pushes the bolt back to eject the round and load another.
Carbon buildup from the M4's gas system has plagued the rifle for years, resulting in some close calls with Soldiers in combat whose rifles jammed at critical moments.
According to the solicitation for the new upper receiver assemblies, the 416 "allows Soldiers to replace the existing M4 upper receiver with an HK proprietary gas system that does not introduce propellant gases and the associated carbon fouling back into the weapon's interior. This reduces operator cleaning time, and increases the reliability of the M4 Carbine, particularly in an environment in which sand and dust are prevalent.""

If getting a rifle you may be trusting your life to, get one that the spec ops community likes. Not one that only came about as a result of defense contractor bribes and backroom dealings that as much as falls apart if dropped.
