If I bought this and one of the Complete Lowers, do I have everything I need to have a functional AR? Or do I need something else. Thanks!

BEST ANSWER: You can add to it whatever suits your fancy. There are countless accessories you can add to customize to your liking. You need buffer tube to make it functional. Might come with the complete lower however.
Will you ship uppers to California?

BEST ANSWER: Yep! As long as you don't have an under barrel grip.

Great product
I bought this upper and installed it on a PSA completed lower. Fired 150 rounds through it with 0 malfunctions. I would buy again and recommend to others.

A Superior PSA Upper!
The PSA quality and this Magpul upper go hand in hand. Price is tough to beat and this is a well made, accurate upper.

Great Product and service
This upper was exactly what I was looking for and I received it within about a week of placing my order. It fit perfectly on my self built lower. So far everything has functioned very well. I have recommended PSA to others who are interested in AR builda. I'm sure I will make additional purchased through Palmetto State Armory.
