As advertised. Great value. Haven’t shot it yet……working on a lower for it.
Cameron Decker –
Received my items earlier than the expected delivery date! All parts seem to be well built. Will definitely order from this site again!
Mike E. –
Great products well constructed, excellent delivery time. The build itself just takes a little time, with a small drill press, assembly was a breeze. Looking forward to taking a trip to the range. Very pleased

The machining was clean. The broached magwell was smooth. The hardcoat anodizing was tough and evenly flat black.Neither the receiver nor the lower parts kit come with any form of instruction. I did a good deal of research online and found more than enough information to finish machining the receiver and assemble the lower.I have not yet purchased the upper so I cannot comment on the fit of the receiver to an upper. I also don’t know about the success or failure of my machining. I used all the parts with no leftover mystery pieces and the parts assembled and dry fired with no apparent issues. I’ll take that as a good sign.I learned a lot about the mechanics of an AR through this process. That in itself was worth the extra effort of finishing the receiver myself.I did not purchase the any jigs or templates. I used a good ol’ Bridgeport knockoff and drew my own prints from information off the internet. Again, much more work, but I have a better understanding of my new AR-15.While this 80% receiver was not the cheapest or the most expensive, the website answered any questions I would have asked about the product: All MIL-Spec, hard anodized, 7075-T6 aluminum, broached magwell, US made, and finally NO FFL REQUIRED.Good product, average price, slow turnaround, mediocre lower parts kit, but the receiver ( the only part they make ) is even better than I expected.
