Exactly what i was looking for - Aero Precision M4E1-T 12.5in 5.56 NATO Complete Upper Receiver with Flash Hider w/ S-One Handguard

I wanted a lightweight, minimalist 12.5 upper to build an AR pistol to add to my collection. This was to be my shortest, non-suppressed rifle that was going to contain an optic and a light, and maybe a grip on the list of furniture to add. Highly doubt I'll use an IR laser/illuminator, but it's nice to know there's a little rail in the front left if I need.

Fits my hand naturally, would easily see this as my new go-to.
