Awesome Upper

This was my first DD upper I've purchased, overall highly impressed. Great fit and finish, paired with an FN M4 lower, which mated up perfectly. Rail and fsp was straight and rigid. Rear sight was tight and lines up perfectly with the fsp. Added a microbest bcg,lbe charging handle, and a birdcage flash hider. Mine also DID come with a sling mount at the 9 o'clock position as well. In the picture it does show a DD dust cover and mine was just a standard one, which I don't care as I feel like the sling mount is much more useful. Overall 5/5 for what I can see thus far without having taking it out yet.
