Well built, as expected - OpticsPlanet Exclusive Daniel Defense Custom Upper Receiver

This complete upper showed in no time at all. Once opened, it came in a well packaged DD box, that was inside of an equally well packaged OP box. Upper came out flawless. Got it added to my lower later that day and took it to the range a few days later where it shot very nice. A little gassy, but nothing an H2 couldn't take care of. Wish it came with an adjustable gas block, but not a big deal. Since its pin and weld swapping that gas block out wont be quick fix but it is doable if some really feels like doing the work, but can also be achieved through buffer and spring adjustments.
