    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?

    .22 rimfire upper for AR15

    Who makes a decent, .22 upper for an AR15, with timely delivery? It doesn't have to shoot 1/2" at 100 yards, but, I want decent accuracy. I've tried a couple of the conversions, but, accuracy sucked. I'd really like to actually practice a little with my ARs without having the expense and noise...
