I want to build an Ar15 that will shoot 9mm caliber. Whats parts do I need to do this?

I believe the different pieces you will need include the barrel, hammer, and a magazine block.

Some of the vendors have 9mm "completion" kits; I think Rifle Gear does.

Other than the things above, many of the parts are interchangeable.

You may also need a different buffer and buffer spring, but I'm not sure.

I actually have all the parts you need to complete an AR15 9mm minus lower/lower parts kit for sale. I have the Rock River 9mm complete upper, Hahn full metal magwell adapter, 9mm spring and buffer, and the 9mm hammer. Let me know if you are interested.
