Again and again

Again and again. My shopping experience with AR 15 is an awesome the prices keep me watching their products and their products keep me coming back for more. I had bought this upper for my first build, it worked so well, that I bought a second. I even enjoyed the peppermints they sent for Christmas, that’s right I said Christmas. Tis the season for love, peace and sweet baby Jesus. God bless everyone. Merica!

Awesome service!

All the parts that I ordered came. All in perfect condition. The buffer tube kit that I ordered had a bad castle nut. I emailed customer service and they had my replaced loaded on the truck that day. I will be back!

Well made.

Aero Precision uppers are made well. Barrels always fit tighter in an AP upper receiver, which I believe is a good place to pick up some accuracy. I also use .001 stainless to shim and normally only a 1/3rd rotation is needed with AP uppers. Others need much more up to a full revolution. Mated with an Aero Precision Gen2 lower you will also have a nice tight lockup. No slop, which I don't see as an accuracy point rather a point of pride in building a tight rifle.
