Soldier Weapons Assessment Team in Iraq, for the gun buffs out there...
http://www.bob-oracle.com/SWATreport.htm
excerpt:
The Iraqi desert was very challenging and harsh, but the current weapons, ammunition and accessories the soldiers took to battle functioned, withstood the elements and were lethal. The weapons that stood-out were the M2 HMG, M240B MMG and the M4 MWS. The M2 HMG and M240B MMG were praised mostly for their ruggedness and reliability. The weapon’s reliability was most important to the soldiers. The M4 MWS’ modularity, size and weight was well received by soldiers issued this weapon system. It enabled soldiers to conduct clearing operations in urban terrain and easily transition from day to night operations.
Although the M4 MWS was reliable, the team observed light primer indentation occurrences in the M16 series rifles: M4s and M16s. As soldiers locked, loaded and cleared weapons prior to and after operations or as directed, the primer was indented. Upon return to CONUS discussions with weapons engineers revealed that each time a cartridge is chambered in an M16 Series Rifle or M4 Series Carbine, a slight indentation is made on the primer. This is caused by contact of the free-floating firing pin against the cartridge primer as the bolt closes. This is a function associated with normal operation of the weapon. The Army conducted tests to investigate the effects of multiple detents on 5.56mm ammunition. No slam fire, or accidental discharges occurred.
However, cartridges are not intended to be repeatedly re-chambered as this may de-sensitize the primer and/or deform the body of the cartridge case sufficiently to cause misfires. The potential for a misfire may occur in as few as 10 to 20 lock and load cycles of the same cartridge. No misfire occurrences were directly observed from indentations but soldiers relayed some occurrences of accidental discharges when going through the clearing procedures and one soldier experienced a misfire – from a round cycled through the chamber numerous times. Further testing is planned to more accurately quantify these conditions and establish the need of a Maintenance Advisory Message (MAM).
As stated above, soldiers rank reliability and durability as key weapon characteristics and are not willing to trade them for anything – to include weight. Similarly, soldiers do not consider the weapon as part of their load, but rather as an enabler. They are willing to carry the weight if the weapon or device increases his lethality. This is best illustrated by soldiers purchasing their own magnified optics and the strong desire to carry an additional sidearm or shotgun for defensive and offensive purposes. Lethality is more important to the soldier than any other consideration or factor.
