Best Billet Upper you can buy period!


Fantastic Upper Receiver. Anodizing is super thick, no machine marks anywhere, the surface of the internal bore of this receiver is actually smoother then the face of a geissele trigger. Domed cam pin takes out fiction and aids in smoothness of cycling the action, I had no need to lap any of the UAR uppers I have built as all were perfectly true, forward assist is slight moved to allow easier access to charging handle (good for lefties), these have a PAD* right under the front take down lug to take up any slop from non matching lowers, in some cases you need to take a piece of sand paper or something similar and sand it down a little if having trouble with the rear takedown pin to fit, which it is intentionally built this way, used these on a couple spikes a couple andersons dpms, POF, PSA and a noveske chainsaw lowers and all have fit beautifully. The strike industries UDC polymer dust covers do not fit this upper, all other dust covers I have tried have fit so far.
