The Stag 10 upper receiver assembly includes a picatinny rail on the top, dust cover and forward assist. Compatibility: Our upper receiver has the same barrel nut threads as DPMS, accepts DPMS barrels, accepts Stag, Armalite and DPMS BCGS and Charging Handles. Once matched with our custom Stag Lower, Takedown Pin, Pivot Pin and Takedown Pin Detent, this assembly can be built using standard DPMS components.
