So, I have BRD.... Help me decide...

To reach out and touch someone with 5.56 at 4-500 yards, you will need decent ammo, like MK262 mod1, Hornady TAP 75gr, remington premier 77gr, GMM 77gr, or similar. Be ready to drop a dollar and up per pop. Almost the same as 308 match, give or take a quarter.

Not exactly...

You should be able to smack a 2-4 MOA target out to 500 yards with a decent 16" gun and XM/M855 ammo. I know my fiance and I have been able to do so with our Spikes Tactical carbines.
