The Colt company developed various carbine versions of the basic
rifle since 1970s. These carbines were intended for all markets - military, law enforcement, civilian. US Military (and some other armies, most notably - Israeli Self-Defense Forces) had adopted the Colt CAR-15 Commando and XM-177 carbines during the 1970s and 1980s. But early in 1990s the old idea of replacing the pistols in the hands of the troops with some more effective, shoulder fired weapon, rise again in the heads of the US Military. In fact, this idea can be dated back to the 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.
