Want to convert the AR15 to 9mm

[MountainMan]

Like the title says, I'm wanting to convert one of my ARs to 9mm. I know I need the whole upper but what other parts do I need to do the conversion?

Thanks

You will need a 9mm magzine block and 9mm magazines, 9mm buffer and the right hammer(I know there's two styles and only one works with the 9mm). Mags come in 20rd and 32rd. I had the Cproducts mags and had good luck with them. They are much cheaper than Colt 9mm AR mags or modified Uzi mags.

I think that is about it.

You would be better off buying a complete rifle.

And if you are going to go 9mm, may as well make is an SBR.

Cheapest and easiest!

I believe there is a different bolt hold open in the lower also.
