    Suppressors Setting up a 5.45 AR Upper: Sights/Optic Question

    Is there any reason not to reuse a MATECH BUIS and an EOTech 557, other than the fact that both are set up to compensate for the drop on 62 gr 5.56 out to 600M? And if you wouldn't reuse them (I'm going to 5.45, for sure), what would you use instead?
