School me on 45 ACP AR Platforms

[BoilerUp]

BU, I was thinking this from the beginning, but Jerry R. said he wanted an AR platform .45, so I didn't mention it. I'd love to have a Thompson! However, with an AR, comes all of the cool and useful AR "stuff". Sights, triggers, controls, etc..etc.., to optimize it to one's own tastes and needs.

I say get both!
