Setup looks awesome! It's funny, I'm building the almost SAME setup right now.
I have a DDLES Glock mag dedicated lower in 7075-AL, Vltor matching, with Vltor MUR 1 upper, Noveske 5.5" 9mm barrel and I ordered my AAC TiRant 9 a few weeks ago! Man, we must have the same taste in weapons.
Very cool! I almost waited for the glock version, but the cheap colt pattern maga turned out to be flawless for me!
