Nice build DD. Aero Precision is a good lower.

Ditch the "F" FSB. I'd go with a flip up sight gas block so you can scope it if you plan on shooting anything with more than a 1x magnification. I have 2 uppers with standard FSB's, an old Colt SP1 that is 2 years younger than I am, which I love, and my A2 Oly upper, which I might tear apart and make into an A3/4 upper with a flip up sight gas block.

Everything else is flip up or a railed gas block. Big fan of the BUIS.
