We get these factory new from Daniel Defense, and take off the receiver from the full upper receiver group. That means that we have received a DD rifle or upper, and taken it apart. The Take-offs are as good as new. Maybe some grease on the receiver threads, but you are going to want that anyway.
Daniel Defense just has a way of making great receivers. These are hard coat anodize with a superb finish. If you are used to military uppers, you will drool over this. Not the military scuffing that you see with Colt, Knights and others. All of those are some of our favorites, but for a civilain rife, it really does not get better. The finish is a uniform black anodizing. The Daniel Defense brand is located on the upper left of the left side of the receiver.
Includes all hardware, including DD branded Polymer dust cover.
