Lower was shipped to my FFL and it arrived in perfect condition and is exactly what I expected.

Exceptional quality


I'm a big fan of Aero Precision and have put together a number of AR15 builds. When it came to building a AR9 I immediately looked to Aero.
The quality is always perfect and all the parts fit perfectly.
1. Faxon barrel and Faxon BCG have performed flawlessly. The LRBHO function from the Aero EPC upper performed each time.
2. After reading a number of reviews on how to set up the buffer, I went with the KAW valley 10oz buffer and the JP enterprises 308 carbine spring. Perfect combo and soft recoil.
3. I looked at other brands for my AR9 build and for the price you cant beat the quality of Aero.
