Nice job dig!
Aero Precision is a local company (for me), use to build lowers for Armailte (poor spelling). I have a couple and they work great. The first I purchased was a stripped lower and built it to my only personaly built AR and IMHO is a buzz saw, come get some AR. It makes me grin every time I take it out. I bought another lower and will build a long range AR in 308 when money allows. I have a another AR bought complete, it is a good rifle just not the same as the one I built
