I wish you were selling this before I finally hunted down one a few months back. I have one with a CMMG upper and it works great. If you want a 9mm AR this is the lower to get. I would buy this if I did not already have one. Great price for what you get. Good luck selling it, someone please BUY THIS so I don't feel so bad. I would use this for a pistol build if I had the money right now. Everybody that sees it or shoots it thinks it's great!!!! 9mm is cheaper to shoot than .556 and you can go to pistol ranges. Plus the Colt type magazines fit perfectly.
