14. The Improved M16 Rifle
The improved M16A1 rifle featured a firing chamber that was coated with chrome. That drastically cut down on the corrosion problems that had plagued the original version. The redesigned rifle also featured a forward assist, that allowed troops to manually tap the bolt forward when necessary. Between the new emphasis on training and instructing the troops on the proper cleaning and maintenance of their rifles, the cleaner firing cartridges, and the redesigned M16A1, the problems that had plagued the original M16 were largely gone by 1968.
For many front-line combat troops, the very fact that they were in Vietnam might have still sucked. However, being stuck in a war with an unreliable rifle was no longer among the reasons that made Vietnam an especially unpleasant experience. As it is, the M16 is a great rifle in the hands of professionals who are trained to maintain and get the most out of it. It is not as forgiving a weapon as the AK-47, but it is a great one for those who know how to take care of it.
