Recently built a 14.5" AR-15 and a 7.5" AR pistol from 80% receivers. Turned the receivers into 100% via a CNC mill, then completed the builds with my favorite components, piston uppers, LWRC enhanced fire control group, etc. Some pics.
CNC milled the 80% receivers to 100%:

Took the second 80% receiver and built an AR pistol; pretty much the same lower build aside from the pistol buffer tube, and added a PWS Diablo 7.5" upper, which has a long stroke piston system (AK style), and a Primary Arms red dot.
Here's the AR platform family shot. The top one is a LWRC M62A configured for longer distance shooting with a 4-14x44 FFP scope.
Now getting into 1911 builds ...
