The Best Stuff!!
by Michael -
These lowers are phenomenal! Just built a 556 with a 10.5 inch barrel. It came out way better than I expected. I would love to do another one and hopefully I will do so soon!

This lower is amazing! Took me no time to build. It was my first build (thank you youtube videos...) and it works great! Looking forward to go try it at the range on my AR15 pistol, as soon as I find ammo :-). I will definitely buy again...
Phenomenal receiver with great features
by Will -
This a solid lower with a pleasing look and some great features. Starting a pistol build and having the threaded pin for the bolt catch and the set screw for the rear take-down pin make this a cinch to build. Also, having the set screw to stiffen the lock-up between the upper and lower. Aero hit it out the park with these! Definitely will be using these in future builds!

Excellent machining, fit, finish. Easy to assemble. Large mag well flare. I personally like the styling. It is much nicer than my Anderson's in nearly every way. To me its worth the extra $ for most builds.
<br>The quality upholds to Aero Precisions' high standards; as have all their products have for me so far.
I'm sold on Aero Precision
by VMS -
This was the first part I ordered for my 1st-ever AR build. I really didn't know too much about building a carbine, but I was fortunate to come across this product which happened to be in stock at the time. This turned out to be one of the best parts I purchased for my build. It's solid quality and it was a straightforward install. I have purchased additional Aero products as a result - highly recommended!
