It’s close. I got a chrome lined barrel and used a Rock River lower receiver.

Kit was from M&A Parts. I’d use them again.

Gas piston is an excellent choice.

I checked out M&A Parts and am intrigued.

I am going to ask a couple of dumb questions.

If I bought this upper receiver kit and this lower receiver, would I have everything I needed to assemble an AR-15?

How hard is it, once you have all the parts?
