Daniel Defense M4A1 upper receiver

This is a new receiver that is a "take-off" from a factory rifle or URG.  This one has the DD M4A1 logo, and is high sought after.

The receiver has an outline of a round towards the front inside of which reads 5.56, and a marking toward the rear which reads M4A1.

Note:  We also have the Daniel Defense logo upper receivers.  Both are identical in construction, just different labeling.
