"From the first sight, the M4A1 SOPMOD is an ideal Special Operations weapon - handy, flexible, with good firepower. But the latest experience in the Afghanistan showed that the M4 has some flaws. First of all, the shorter barrel commands the lower bullet velocities, and this significantly decreased the effective range of the 5.56mm bullet. Second, the M4 barrel and the forend rapidly overheats. Third, the shortened barrel resulted in the shortened gas system, which works under greater pressures, than in M16A2 rifle. This increases the rate of fire and produces more stress on the moving parts, decreasing the reliability. While adequate as a Personal Defense Weapon for the non-infantry troops (vehicle crews, clerks, staff officers etc), M4A1 is, by some accounts, less than ideal for the Special Operations troops, at least in its present state. The idea of the complete re-arming of the US Army with the M4 as a money-saving measure, also is somewhat dubious."
