I bought new last fall here on Arfcom, it has less than 200 rounds down the tube.
This is a factory upper, not a home build and it does NOT have dremeled feed ramps.
Barrel is marked "STAG ARMS 5.56 NATO 1/9"
Everything in the pics is included - ie. upper, B/C/CH, Samson HG and ARMS rear sight.
Asking $600 shipped to CONUS. Will entertain reasonable offers. Thanks for looking.
