With current ballistics from the 6.5, or 6.8, or even the 7.62x51(.308), which have flat out better ballistics than the 5.56, why is the "same ol', same ol'" 5.56 still standard military issue?
I'm not bashing the AR's, despite their initial problems as well in Vietnam, they have their place as a combat rifle, and in history, however, if evolution and technology can make a more effective combat round, we should be all over it.
Regardless of the OP email, which I read some time ago, it doesn't matter, the crap over there is the same crap. We are just better at figuring it out.
I agree the 5.56 is still a good round, but the 6.8 is better, and the .308 has been there and done that effectively.
just my .02 cents, and wanting to believe our soldiers have the best available. NOT a "cost analysis" bureaucratic decision.
