The only reason the SAW is considered "effective" at 800m and 1000m is because it's employed in a more stable firing position than a conventional rifle. An M16, even in a prone supported position, is still not as stable as an M249 locked in to a tripod and T&E. Even a bipod on the M249 is good enough for the role it's serving.
For anything beyond 600m, it's my opinion that type of engagement is reserved for your crew served weapons. They have both the manpower and equipment necessary to accurately and continuously reach out and touch.
