So the rifle went from initial acceptance, including these kinds of stupid last-minute design changes that are common in any project, to large-scale combat deployment within a year; normally, there would have been years of incremental usage to catch these bugs Large organization needs to roll out a new model on an accelerated timescale. Cost cutting and time saving decisions are made, which have disastrous synergistic effects in the field. Sounds very familiar. EDIT: In order to understand the design genius of the AR-15/M-16 rifle, hold 50 rounds of 9mm pistol ammunition in your hand, then 50 rounds of 5.56 ammo. It varies by the particular kinds of ammunition, but on average, they weigh around the same. Yet the rifle is many times more powerful. How is this so? 1) More propellant weighs a lot less than more lead. 2) Energy goes up by the square of velocity.
