Aero Precision is working on a new AR-15 lower receiver – likely their Gen 2 Lower to go with their Gen 2 Uppers. These lowers obviously have some pretty slick aesthetics with the angular surfaces, the stylized fence around the magazine release, and what appears to be an integral skeletonized trigger guard. However, the real story here is that magazine well. Just look at it!
I like it, although I would have preferred s winter trigger guard.
