I used the Aimpoint Acro P-1, had to find an mounting plate specific for it. I moved to the Hex Dragonfly and it fits great and Springfield Armory had the mounting plate in stock. As far as lasers, I'm running a Surefire XC2.
Hopefully this gets to you in time? I found it here, and seems they have some in stock as of this post.

@SeymourSmithers just picked mine up from my FFL, I have the same issue. The alignment is just a tad off. My FFL told me that he had another EVAC owner had the same issue, and is going to get in touch with him to see if Springfield fixed the issue.
