My New Go To
Aero is an excellent option. This 18" Wylde 1/8 twist 416 SS rifle lengh gas system is an awesome and accurate upper. I use a Geissele H1 buffer and it works flawlessly. AR15DISCOUNTS is my new go to. Especially as a California resident, places like OP will not ship an upper even if it within the letter of the law. Shipping time was fast, and it was packed well. A+ experience.
USGreat upper
