got a very little fired (about a hundred rounds, just enough to break it in), DPMS Sportical Bull Barrel Upper. Heavy barrel with a recessed crown and the slick sided receiver. Complete with bolt carrier and charging handle. I bought this to use while I was waiting for my new upper to come in, but of course as soon as I bought it my new upper was ready. Asking $425, willing to travel in PDX metro. No trades please. As is, no warranties. Please email or pm for pics. This is a 16 inch heavy barrel, forgot to mention that since I am too lazy to upload pics.
